Littleton Heating and Air Conditioning

Excellent company to do business with. They took the time to thoroughly check out our old HVAC system before making any recommendations. Derek and crew were very personable and detailed oriented. We also had a mechanical room that needed some updating, which they also handled along with installing a new furnace, air conditioner and humidifier while keeping us in the loop as work was finished. They left the area clean and neat. I would certainly recommend this Littleton based company to anyone needing work. You will not be sorry that you did.

After talking to several A/C contractors, I decided to choose Littleton Heating & Air Conditioning. Their price was really good and they did a very professional job. They were also very careful not to get dirt on my carpet as they were working. I am very glad that I choose them to install the A/C system for me. Services: A/C system maintenance, Install AC, Install thermostat, Installation, Thermostat installation, Heating system installation

Littleton Heating and Air Conditioning has been a terrific company for us over the many years we have used them. Excellent service, Professional work. Very knowledgable. Good response time and friendly service, in office and in the field. Derek installed a new Daiken Fit furnace and air conditioner unit for us in April of 2019. We have been nothing but pleased with the new system.

I set it on automatic with a 10 degree gap, and rarely ever have to touch the thermostat. There is circulating air from time to time and then when the furnace or air conditioner turns on, we rarely notice it, as the transition is quiet and smooth. We have lived here for 68 years and this system is the best we have ever had.

Littleton Heating and Air went above and beyond our expectations! We decided to upgrade our 13 year old furnace and A/C for our two story home as we were finding the upstairs was hard to make comfortable. Derek recommended we go with a Daikin heat pump to manage our complaints and have a furnace as backup heat for the really cold winter days. We scheduled our install and we had our full system up in two days!

Everyone on the job was really professional, knowledgeable, and helpful throughout the whole process. We were kept informed of everything going on and provided with all the information we'd need for our system. Along with the new system, they adjusted our airflow to be better balanced. Derek's recommendation did not disappoint and our home has been the most comfortable it has ever been. The system constantly moves the air around at a very low speed and helps remove all of the cold spots we used to have upstairs. Highly recommend anyone to go with them!

Derek was awesome. Wonderful service performed on a timely manner. Didn't have the part but went out of their way to get it. Many thanks! Will always recommend Littleton Heating and Air. Service: Install thermostat

Littleton Heating & Air Conditioning sold me what we needed not over selling. They are very knowledgeable and care to do the right thing not just put in like kind. They take time to get the install in the best way. They also took the time to solve some of my air handling problems. Very trustworthy and helpful company & people Services: Install AC, Heating system installation

I have used them several times over the course of 40 years and have always been extremely satisfied with their work and work ethic. After moving from my house to a new condo my ac unit at the new condo was not working right and it was under warranty the company that installed the ac unit sent out 3 different teams at 3 different times to fix the ac unit, they did not succeed, when they told me they would no longer try to fix it i called littleton heating and they fixed it in one attempt

We recently bought a new home and the A/C Unit went out. Derek came out and provided a review of all our options, without being pushy at all. He was professional, knowledgeable and courteous. We decided to replace our entire HVAC system with new duct work and vents. The team did a great job and were incredibly efficient and respectful along the way. Would highly recommend to use again!

Review from my mother Susan Hiett: This company installed by heater two years ago and Derek was extremely helpful, knowledgeable, and professional. He has since been back every year to check that the heater is running efficiently and has always been helpful and friendly. I have recommended this company to several of my friends and family.

The folks at Littleton Heating & Air Conditioning were awesome. I was dreading having to deal with an HVAC contractor to replace our 40+ year furnace and do an AC install but instead I was pleasantly surprised. We were treated like family instead of being treated like just another job. I got two other quotes that were cheaper, but we made the right choice by going with Littleton H&AC. Attention to detail, and customer service that was on point. They made suggestions during their quote that the three other estimators never brought up.

I did a lot of research and was convinced by Littleton Heating in order to maximize performance I needed to go with a smaller ton, more efficient unit for my duct work/sq footage. The guys came in and created custom duct work and gas line solutions. It can not be underestimated how valuable catching all your cool/hot air right away with angled/flawless new duct work. This is what they delivered. I'm pleased with my new system, huge upgrade. 5 stars.

I contacted multiple companies but ended up choosing Littleton Heating and Air Conditioning to install my new furnace. Not only did they give me a great deal, but they were very quick to both obtain and install the new furnace! I asked them to do the work and it was done within two days of my request! Derek performed my install and seemed very knowledgeable.

He did a great job and was even able to stop by on short notice two weeks after the install to help me troubleshoot (successfully!) some thermostat settings I had issues with. I plan to give my business to this company again and will be contacting them soon for additional work cleaning my ducts! Thank you Littleton Heating and Air Conditioning!

I have allergies and asthma. I recently bought my house and when colder weather came in and we had to start using the furnace I started waking up everyday with asthma. I contacted a few companies about replacing the HVAC system and when Darek came out he suggested that I install a Reme Halo whole house air purification system in the mean time while I figure out the HVAC thing.

He also has been understanding about the fact that I just bought a house and explained to me how to DIY install it to save me some money. Two days after I installed it my asthma went away! Still in talks with Darek about upgrading the HVAC in my house but so far the support and consideration for my needs that I've received from these guys has been outstanding.

Diagnosed the problem quickly and fixed it right away. We had burned up contacts in our ac unit and he also did a great tune up. Derek was very professional and was a pleasure to have around for the short time he was here.

Dan was very informative and helpful in servicing my furnace. He encouraged me to ask questions and I learned some easy but important maintenance tips to ensure my heating and cooling systems will be efficient and reliable!

After having several companies come quote me for a new A/C and furnace, I settled on Littleton Heating and Air Conditioning based on their ability to explain to me what my house needed. It's hard to find companies that won't take advantage of someone with no knowledge of their industry and they answered every question with courtesy and took the time to explain it to me. When they were in my house and after they finished they were very courteous, clean and helpful. I would recommend them to everyone I know.

What a relief to have real professionals who don't just hand you a quote, but explain what things mean and why. They took the time to make sure I knew not only how everything worked, but why it works that way. Courteous, polite, organized AND efficient...and that's saying something because our situation was a mess due to fault of the previous company. You can't go wrong with Littleton!

Steven and Rob made the installation experience very pleasant and went above expectations to ensure the installation went well. The installers were very good about answering any questions and ensured that everything was installed correctly. The wrong furnace model was ordered and Steven and Rob went and picked up the correct model. They were very apologetic about the mix-up.

There was also an error with the original order in that a new line set was not part of the original estimate. The company was very good about making everything right with the project. I would highly recommend this company for your heating and cooling needs.
