Our experience with Bell was excellent. From the start, our project manger, Lance, explained our options and what to expect very well. We had a new boiler installed, moved the entire leaking basement zone from the concrete pad to the walls/ceiling, and replaced radiators. Nate and Derrick worked on the project for a week. They were friendly, professional, diligent and openly communicated their plan and any decision points quickly.

We greatly appreciate how they took their time and limited the impact to our drywall as much as possible all while keeping work zones clean. We are incredibly happy with the end result, excited to have heat restored to the basement, and plan to use Bell for future services.

My rating was originally won but I have had time to deal with Bell a number of other times and I am very happy with them.

Bell Plumbing and Heating technician that showed up wanted just under $1000 to install a dishwasher. He said it was the industry standard. Old dishwasher was already gone, no issue swith existing plumbing or electrical, and it ended up being a 20 minute task with competitor company we went with.who charged around $200, a seemingly fair price for the time and skillset needed for the task. Bell still charged the callout fee though. Recommend looking elsewhere for your plumbing needs.

I recently used Bell to replace a 30 year old boiler in our house that goes to our radiant floor heating and domestic hot water supply. Nick and Josh were great. Super personable, easy to talk to, walked me through the new system (it was extremely complex in my opinion), and got everything working in the estimated time. They did a massive amount of work.

The old system was not installed to code, there was quite a bit of ductwork that needed redone and a lot of piping to make it more maintainable in the future. I would recommend Bell Plumbing and Heating and will continue to use for future work.

Like a lot of customers, I regret that I ever used their services. I needed to replace a filter for a humidifier. They ended up charging me $510 with the trip charge. It shouldn't have cost more than $120-$180. Within two weeks, the unit broke down. An electrode on the unit had burned up. My suspicion it was there shoddy work but I can't prove.

Another technician says this never happens., They said it should be warrantied under their work and offered to come out free to look at it. They came out and looked and gave me a $2,100 estimate to fix it. They charged me $265 for a trip charge. I should have kicked them out of the house. I had a reputable company come in and fix the problem for $315 plus $60 for another filter. Buyer beware.

Jay is a godsend! My water heater went out early Friday morning when I was about to take my shower. He was immediately dispatched and was here within the hour. He did a complete install of a brand new water heater, expansion tank, the works. This man cares about his work, which is nigh unheard of anymore, especially in the trades (I know this because I once was one).

The price was not cheap, but I am very happy with the work (and the hot water), the attention to detail, and above all else, the honesty! Other trades people need to take lessons from this man in the ways of the truth. Thank you so much again for helping me in my hour of need! Sincerely, Joe

The one star is for the service tech, who was efficient and polite. As for the company, they charged me more for a new garbage disposal and installation than I am going to be charged by a different company for the purchase and installation of a new dishwasher! Do not use this company. They think too much of themselves. They asked for a review after the visit. I gave them a very poor review. They didn't even bother to respond.

Gustavo got my central heating/air back up and running after some problems with a part on the furnace. He was very professional and knowledgeable, polite and on time. I feel very secure about having my heating/air unit working properly. Thank you again, for another great experience with Bell Plumbing, Heating, Air Conditioning and electrical service. Keep up the great work!

I needed a sink hookup and some other stuff done. Bell was very responsive and was available the next day. They're a good size company who have been in business for almost 100 years. I was very happy with the work that was done. I've been a landlord for over 25 years, I have used a lot of contractors and know what good work looks like. The technician, Jay H, did a solid job. I will definitely use Bell again.

Our water heater was installed by Bell 8 years ago, and is still under its 12-year warranty. Over the past year we had to turn the thermostat higher and higher to maintain a hot temperature. Finally, we had to turn it to the "Very Hot" setting and it was still just barely adequate. So we had Bell come out to see what was the matter. For a very modest charge, the technician Chris, did a 14 point inspection and replaced two defective parts: the dip tube and the expansion tank. Unfortunately, after a few days it became apparent that this had not solved the problem.

So Chris came out again. Since the gas pressure and flame were fine and the tank and all its parts seemed fine, Chris figured the only remaining cause could be with the thermal sensor in the gas valve and thermostat part. Sure enough, when he removed that part, it turned out the sensor was covered with mineralization, which was preventing the thermostat from working correctly. Chris replaced the part - all at no additional charge for either the part (under warranty) or his labor for the second visit. Since then, the water heater has been working fine.

Found water in our crawl space that we identified as coming from our humidifier. Found Bell via Google and luckily they were able to send a tech out within a couple of hours. Nate was extremely professional, wore a mask and shoe covers, was extremely knowledgeable and friendly and handled all of our issues in a timely manner. I found services to be reasonably priced and signed up for a yearly membership which covers a lot of the in incidental costs. Highly recommend Nate and Bell for any of your HVAC needs.

They left a hole under sidewalk and never responded. So I hired someone to fill since they ignored my request. They replaced a water line from the house for $6,000.00. I do not recommend

We have had multiple inspections done on our property by this company recently. Aaron took care of our furnace inspection and told us what we could do to make our air quality even better. He was very friendly and has a great sense of humor. Austin helped us with a complete electrical inspection. He was polite courteous and explained everything clearly. I feel confident that I know what electrical issues I have on my property now and what work needs to be done to fix them. Thanks!

Bell is the best! We've used them for a while now. Our furnace started doing some weird things this week, so I called at about 4:45pm to set up an appointment, and spoke with Heather, who was a delight. She scheduled me an appointment for the same day! I was NOT expecting that, especially so late in the day, and wow - what a nice surprise! Chris came, and he was awesome.

Super honest about what was going on, inspected everything and was straightforward about what I could and could not wait on. It's always a little nerve wracking when you have a service technician in your home, because it's a big unknown - how much am I going to spend today? I feel so much more at ease now, I wasn't out hundreds (or thousands) of dollars, and it looks like our furnace is going to get us through the winter with no big problems. Thanks, Chris, Heather, and the whole team at Bell!

A friend recommended Bell Plumbing and Heating when my furnace wouldn't turn on this fall. The issue was anything but straightforward and ultimately required coordination with the gas company for the furnace to function properly. I am grateful to all of the professionals at Bell who trouble-shot and ruled out potential issues one at a time, but I'm sending an extra special thank you to Nate for his tenacity in not only identifying the problem, but also ensuring that the furnace was up and running after the gas company had to replace the meter.

Been using Bell for years and recently had them come out and look at a part on my furnace that was making some noise. By itself this part is $250.keep that in mind. So the guy proceeds to look at the functioning--but noisy--part and says he can replace it for $1,200 but that will just result in a cascade of other failures. What I really need is a new furnace for about $5,000. Oh, my A/C condenser also has a few years on it so I need to replace that as well. So, a whole new system for $10-$15k.when would I like to have Bell's engineer out to design it?

All this for a $250 part that is making a little noise. This is one 10 year customer who has now deleted Bell from my address book. Oh, forgot to add that I got another quote to replace the $250 part, which was $600. They also said the part might keep working for a long time and the sound did not necessarily mean failure was imminent.

We've now used Bell 3 times over the past 3 months. Each time we've been lucky to have Jay H. as our technician. He is always able to quickly diagnose the issue and make recommendations for how to repair. Jay continues to be great to work with. He communicates well and is always friendly and professional. He builds trust with his customer from the very first visit. Frankly, we continue to use Bell **because of** Jay and highly recommend him. We also continue to be pleased with Bell's office staff, both scheduling and billing: everyone is always helpful and knowledgeable.

I had furnace issue. Shaun Reynolds from Bell Plumbing Had shown up for the work to be done. Shaun was very friendly and very knowledgeable. Went straight to work. Explained everything that needed attention. The bill was absolutely fair. Also I should point out that Bell Plumbing has a first rate customer service. This company keeps you in the loop as to ETA of Bell's employee to why they may be late which makes me feel valued as a customer. Grade for all around service and professionalism.(+A) Keep up the great work Bell Plumbing.

They wanted $1400.00 to replace a valve in my shower and they were using my parts not there's. What a rip off. This is straight up the definition of GOUGING! Shame on any company that takes advantage of people like that. Tom, I completely understand that you would deny what actually happened. It was $1400 minus a veterans 15% discount down to $1200.

Then when I said absolutely no to the proposal, he dropped it to $1000. This only included replacement of the valve. Nothing else! I just hired a certified, licensed, bonded, and insured company with fully stocked trucks and 24 years of experience that will not only replace my valve, but complete the entire project I started for 1/2 the price you were going to charge. Seriously, look at the majority of your reviews, almost all of them are, you're company overcharges for the work.

It tells a lot about a company that starts the proposal at $1400 and then lowers it to $1000 after the customer says no. Especially when your proposal was still $600 more than one of your competitors. Treat people fair and do quality work and you'll keep them as a customer forever. Treat them as I was treated, well, you've lost me as a customer FOREVER. Stop defending your actions and just bid your projects fairly.

Great job experience! Nick came within a half an hour of my call. He was friendly and knowledgeable, and showed me all the options and prices. Best of all, he fixed my plumbing problem! Thanks, Nick! Oh, and Heather was very nice and professional in getting me an appointment right away! Thank you, Heather!

If you want to be ripped off, by all means call these folks! BE CAREFUL OF THESE CROOKS. They tried quoting me $1,800 to do basic cleaning on my tankless water heaters. THEY CHARGE YOU FOR THE TRIP TO QUOTE YOU. The customer service tried to say it is industry standard to charge a trip fee. Yes, it is industry standard to charge a trip fee for. diagnosis or repair, BUT NOT FOR ROUTINE MAINTENANCE for something in which you should already know the cost of.

Normal costs for this routing maintenance are around $150 per water heater not $900. At their cost you are better getting a new tankless water heater every couple of years. On top of that their heating people had a "team lead" who tried.

Just had bell come out on Monday to replace a motor which was at least $1000 dollars and supposedly they fixed the motor which was making the noise. Well I don't see any difference from today than yesterday. When they were here is was quieter than it is today. So now coming back not for another three days. Not happy. Bell used to be good not anymore.

I have a five year old furnace that was really noisy(oil canning) and running hot because of air flow problems. Ive had at least 4 other HVAC companies check it. Diagnosing didn't fix it! Ryan told me HVAC is licensed, but many technicians don't know about high efficiency furnaces and air flow rpoblems (there a ton of complaints on this on internet) Anyway, he figured out what was wrong, my furnace is running smoothly!

In the past I have had good service from Bell Plumbing and Heating. My air conditioning unit was not working, so I called them in September to make an appointment. The earliest appointment they had was October 8th. In the meantime, we have had above average temperatures and have just been miserable in our home. October 8th comes and I have had no confirmation of my appointment, so I decided to call in case there was a problem.

It turns out there WAS a problem. My appointment was scheduled between 10 a.m. to 12 p.m. Low and behold, I am not even on their schedule! OK, mistakes happen. I asked when they would be able to reschedule, thinking the error was on their end so they would schedule me ASAP. Nope. They couldn't schedule me until November. Their error and you want me to wait until November? Really poor customer service. Needless to say, I called another company.

$3000, 4 in person visits, 1 no show visit and my AC still does not work. Unbelievable. Now I can't get anyone to call me back to take care of this mess they created. To say I am dissatisfied and disappointed would be an understatement. Beware, you have been warned.

Our experience with Bell plumbing, heating and air conditioning has always been good. Yes, they cost more, but there expertise is tops and also the quality of their parts. We just had our air condition serviced under warranty for a refrigerant leak by one of their service technicians who’s expertise and communications skills are tops. We plan on asking for Roke the next time we need someone to service our air conditioning.

I would give no stars if possible. I called Bell Plumbing about fixing my garbage disposal and they said that they could come in ten days, on June 11th. I agreed to this appointment. Bell Plumbing then left me a message on June 10th at 4 p.m. saying that they were cancelling the appointment because they were too busy with other customers and that I should call to reschedule the appointment.

I did indeed call Bell Plumbing and told them that I would be rescheduling the appointment with another plumber. Cancelling appointments is NOT ACCEPTABLE, particularly for no legitimate reason on short notice. I had rearranged my schedule for the week so I could be home on June 11th for the plumber. I refuse to accept such inconsiderate, abysmal customer service.

I booked an appointment in early April to have my HVAC serviced and the day before Bell Plumbing and Heating called to reschedule the service because it needed to be a certain temperature outside before they could test the system properly. Not a problem for me and I immediately put it on my Google calendar that they were to return on May 4th. I called the company late in the afternoon on the 4th to let them know that they had not shown up for my scheduled appointment, they informed me that I was not on their schedule.

I live by my calendar, I am a busy person and my time is important, not my mistake. They rescheduled me for the next day because of their mistake and called me to say they have a technician available and could I work them in earlier than what was agreed upon. I said yes. The technician then calls me and says there is no parking and told me that they don't service my address because of the parking issues.

Nobody in their main office at any time ever mentioned this to me. He said he would call his office and call me right back. Twenty minutes later and no call back from him so I had to call their office again whereby I was informed that they were canceling the appointment. I am in the service industry and have been for more than 30 years, this is wrong in so many ways.

You can judge every service experience by two words, MAGIC or TRAGIC, this easily falls into the TRAGIC category. Thanks for wasting my valuable time Bell Plumbing and Heating, I'll make sure to dissuade anyone from using your company to service their needs.

Bell's longevity in Denver has made them cocky. DO NOT use them. Recently I got a kitchen faucet replaced for $250 from another plumber - Bell had installed the same one 8 years earlier for nearly $500. When it needed to be replaced, they wouldn't even look at it if we didn't pay nearly $300 and then they were quoting nearly $900 on top of that for the same new faucet.

They installed a furnace for us years ago (now I know how over priced it was) and the electrical outlet they were required to install per code has NEVER worked and they refuse to fix it. DO NOT use them; we have many smaller, independant plumbers in town who deserve our business.

Bell heating and plumbing are a bunch of crooks! They charged me $407 dollars to come and diagnose our HVAC unit. After the tech was up on the roof for over an hour he came down and told us we needed a new motor and it would be almost $5000 dollars to fix. mind you we are a church so we have a lean budget and this unit is not even 5 years old. so, We went elsewhere and got a second opinion.

The unit only needed a belt and a pulley, and ended up only costing us $125 parts and labor! Do be fooled but the trucks and uniforms they a liars and crooks! I will be pursuing our 400 dollars, and reporting them to the state of Colorado for deceptive business practices!

I very highly recommend Bell Plumbing! We had a very big job that came out of the blue, and they went above and beyond to help. I was visiting my elderly father on a Tuesday and noticed a gas leak outside. Xcel came and immediately shut off the gas due to the leak outside and also one inside. This was in February, and temps were predicted in the teens, so not having natural gas was a big problem.

Bell got Brad out the next day to make an estimate, and sent two technicians on Thursday to rework the outside piping. At that time they tested the whole system and realized all of his interior pipes were leaking and had to be replaced, in order to get the job done Adam came on Sunday and worked all day. They didn't even charge us overtime because my Dad is almost 90 and it was going to be so cold.

We were really fortunate to have called Bell for this job--they had the ability to give the resources needed to address what turned out to be a major issue. Brad and Adam (and one other tech whose name I didn't get) were so professional, hard working, and really nice people. Even though it was unfortunate to have this issue, especially in winter, Bell took care of the problem in the best way I could imagine.

This is NOT the same Bell Plumbing you've seen all your life. Very unreliable, after wondering if they were going to show up I called to verify the appointment at which time I was told "oh sorry we have to change that we were just getting ready to call you". Believe all these low ratings. I could have saved myself a lot of time if I would have.

Absolute scam! I agreed to the $49 service charge. Literally, "Paul" opened up the panel of my A/C unit, and within 3 seconds said "It's broken. It will be $305 to diagnose why, which does not include parts or labor." Are you kidding me?? I thought that's what the service charge was for, to diagnose it! I paid the $49 but will NEVER call upon Bell again, and I encourage you to look elsewhere!

I went to the retail store today to look at kitchen sinks and found the retail/parts store is permanently closed. There is a sign on the door that says they couldn't compete with big box competitors or online sales. Yes, I guess that is right when you are charging 2.5 to 3X the price you can buy the same parts for anywhere else. Never have I gone to Bell and found anything priced competitively.

They even had a stupid return policy. Unfortunately the buying public voted with their dollars and put this legacy retail establishment out of its misery. They simply refused to adapt to the market. (Why did I go? They did have a nice showroom and the staff was knowlegdable). The sign went on to say they now schedule design consultants and still do repairs. Read those reviews. Looks like the ridic prices moved from the floor to the field. Dead ringer.

Absolute joke of a company. This company has been out to my condo 3 times to install a thermostat, and my problem has only gotten worse. Before contacting this company, I had an older thermostat that I wanted updated. The thermostat worked fine, but I'd wanted a newer model. Trip one, they sent a box truck, and then stated that they could not find anywhere to park it (I live downtown), so they would have to reschedule for the next week.

Trip two, they sent a smaller vehicle, with someone who was not certified to work on my type of unit (which was clearly stated in the notes) so they had to reschedule. Trip 3 someone finally came out and installed the thermostat and I was happy, until the next day when I realized that my apartments air conditioning did not work, despite being triggered by the thermostat.

I called to have someone come figure this out, and they informed me that there is a $46 fee for that. This is absolutely unacceptable. If they do not fix the issue this time I will end up spending my own money elsewhere to fix their mistake.

I have bought a part I needed for my furnace before - $75 or so for an igniter. I believe it was a Sunday and they were the only ones available/open. Great service. Called them out this morning as my furnace was out - the igniter I installed melted. Not sure why - the technician was not sure why either. Could have been the gas outage we recently had where we had no gas for days. $49 for the service call - no problem I thought. But, to replace the igniter and have a technician install it was $471.

Time was about 1-1/2 hours. Maybe two hours when you count the drive? So, roughly $200/hr is my guess. You do the math, you can get lawyers for $250/hr. I get they use union technicians, there's training, gas etc., but really? For a part that retails $75? Wholesale on it is less than $30. I could not wait and did not have time to call another technician out and play that game.

Their pricing is national average as they were selling it to me. Guess common sense is not used here and I know they have a business to run. The technician was great, very nice etc. No issues there. Do yourself a favor, if you can wait, use a local well reputable small hvac that is not going to charge "National Average".

Should have read the reviews prior to scheduling them! I used them only because they had serviced our new home for the prior owners. I had them come out to look at our humidifier and make sure it was operating at full capacity. They charged me $165 at that time. Later that day we noticed the "needs service" light on. Called the company back out and explained that the light was now on.

The sent the same technician back out a week later to see what was going on and he wanted to charge us an additional $670 to service it! I told him he could respectively leave! Can't prove that he did anything to it; but total rip off! Incidentally, I looked up the cost of our humidifier; we could get s brand new one for $20 more!

This company is really criminal. Our furnace wouldn't start and the problem turned out to be a blown fuse. The service guy told us the fuse was hard wired to the SSU unit and he would have to replace the entire SSU which would cost almost $900 (see attached invoice.) I ended up calling our electrician and replaced the fuse myself for $4.00. These guys will take advantage of someone who is without heat and doesn't have any home repair knowledge. Beware they have no problem charging $900 for a 4 dollar fuse.
