The life expectancy of a heating and air conditioning system varies depending on type, manufacturer and usage. As a general rule, if you have a unit that is older than 15 years, you should start looking at replacement options. Sure, there are units that we see on occasion that last 40 or more years - but they are (a) the exception and (b) typically inefficient when compared to today's equipment.
Gas furnaces are the most common type of heating system we service and install in the Philadelphia area. If your furnace is making odd sounds or struggling to keep you warm this winter, contact us to set up an appointment with one of our service technicians. Our HVAC service company in Philadelphia works on all makes and models of gas furnaces.

Used WF Smith years ago with my house to install ductwork throughout and a new Lennox. Had a problem last year with my AC not communicating with the thermostat and then this year with the refrigerant leaking. Called a couple local company but all wanting to just make a buck instead of going through my warranty. WF went through the warranty process for me, responsive and diagnosied the problem, always followed up and technicians always arrived on time and respectful. Will be using them in the future for all my AC problems.

W.F.Smith delivers! From the original sales process to final installation the team was exceptionally professional and detailed in their work. The sales process was very transparent without any over selling - they provided choices with pro's and con's and supported my choices. The install team was very knowledgeable and answered my numerous questions.
The were personally invested in the finished product function and look - you can see the detail in even the simplest of things. They stand behind the product and the installation without a doubt. It's a quality oriented organization.

I called this company out after my Lennox system being down for 10 days. The company that I normally use had misdiagnosed the problem not once but twice and after two technicians, many hours, freezing temperatures in my home and a quote for a $20,000 new system in a last ditch effort I called WF for a second opinion. WF sent out Jon - who within 45 minutes, diagnosed the issue, grabbed the part, gave me the price and installed in.
After less than 2 hours my heat was pumping again and my house was warm. I was blown away. Not only that but the VP followed up - can you say customer service? They have a new customer for life. Thank you WF SMITH! Look no further than this company.

W.F. Smith had maintained our 25 year old heating & a/c system for all these many years. We finally decided to install a complete new system which they just completed for us last week. They did an excellent job & the 2 service reps who installed the system were polite professional & timely. We had several contractors bid on the job and W.F. Smith was very competitive with the other bids.
But after over 20 years now with them it was an easy choice to stay with W.F. Smith who we knew & trusted for so many years. We are quite pleased with their company & the newly installed equipment.

I did a complete HVAC replacement of my heat and AC systems adding an electronic ultra violet air purifier and germicidal UV as well. Also, a steam humidifier was added to my system. W.F. Smith is a first class operation providing state of the art equipment, installation and maintenance. Their work not only met, but exceeded my expectations. Their two man crew, Bill & Will, were prompt, courteous, competent and highly professional.
I've worked in mechanical engineering situations most of my life and can honestly say that W.F. Smith is one of the finest HVAC contractors that I have ever had the pleasure to deal with. Steve Kozik, Lambertville NJ

We are very happy with the sales and installation experience we had with W.F. Smith. Dave Smith was very good in explaining the different options available to us. He was very professional and did not try to upsell or push us into anything. In his written proposal, he provided us with good options to custom fit the system to our needs and budget. We were very happy with our installation.
Bill and Will were very professional and polite. We could not have asked for a better team to install our new furnace and air conditioner. They did a great job and cleaned up everything as they finished the work. They took us around and explained everything and patiently answered all our questions. We would recommend W.F. Smith, Inc, Dave Smith, and both Bill and Will to anyone. It was a pleasure doing business with this team. As a positive side note, we cannot believe how quiet the new Lennox furnace is compared to our old one. We are very happy.

W.F. Smith installed the HVAC system for our house that we had built in 2013. We had to get a part replaced on our AC unit a few years ago and WF Smith sent Dave out. We see him usually twice year now for our maintenance checks that are part of a plan that we purchased. We also had him move the location of a thermostat for us last year as well. Dave's the best, and I've been meaning to write a review about him for the last few years.
He's friendly, on time, trustworthy and provides excellent customer service. He takes the time to explain to customers what he's doing and why, and will give you his honest opinion if something you ask him is necessary to get done and spend money on. It would be nice if more companies had employees like Dave.

Critical: Quality WF smith did a great job installing my furnish and AC unit. My AC unit went out in 2 years with minimum usage. I was expecting Lennox unit to last at least 5 years. Even though parts are covered, labor is going to kill me. Lennox and contractors are point figures at each other and I am with AC for a week with 80+ degrees.

I highly recommend W.F. Smith. We had several HVAC providers in to analyze our needs and provide proposals. W.F. Smith was the only one who truly listened to our issues and came up with the right solution for our needs. They were on-time, thorough and professional. We are extremely pleased with the new system they installed for us. It has kept us comfortable through the winter's cold and this summer's heatwaves while lowering our utility bills. I'd say W.F. Smith is best in the Philadelphia area for HVAC services.

I was in the need for a new ductless air conditioner due to a medical emergency. I found WF Smith on line and saw they were in the neighborhood. A representative, Dave Smith called me promptly and set up an appointment. Mr. Smith arrived on time and presented great options in replacing my current unit. The estimate was reasonable and he was able to replace our present unit within a few days.
This was great as a upcoming heat spell was in the forecast. The installers arrived on time and were neat in appearance and courteous. They were efficient in their installation and were so quiet I almost forgot they were working. I am very happy with the unit. The appointment, estimate, consideration, installation, and customer service was exemplary to any other heating and cooling company I've ever dealt with. I highly recommend them.

Lovely company. Used them for the first time in an emergency situation, they are reliable, fair, and extremely knowledgeable. They were able to get out to two different properties experiencing two separate HVAC issues over the coldest weekend of the year. When one fix didn't work, they supplied a plan b to ease mine and my tenant's mind that the issue was being handled. Office staff is lovely. I think her name is Donna? Super sweet. Offers small business type service you can barely find these days. Highly recommend.

Bizarre experience with a service call for preventative maintenance on an air conditioner that is working fine both before and after he came. He (Dave) told us the starter switch is broken ($300 repair) and the compressor would not come on (it comes on fine; Its 91 degrees outside, 72 in my home, and 54 degree air coming out of the vent). I called to speak to one of the 5 owners.
I was told that one of them would call me back. Apparently they weren't all that interested in this bizarre event, as they never got back to me. The secretaries (2 of them) are very nice. My prior experience with them on a major repair went great also. So I am still shocked by this bizarre event and lack of response by ownership. I wanted to give them another chance but they have made it very difficult.

A1, gold star! After getting ripped off by several small AC/heating companies we decided to try a slightly larger company. Still appears to be a small business, which we like, but they have fantastic dispatch, clearly stay up to date on new technologies and practices, do detailed invoicing, etc. (We have 10 year old electric heat pump units that don't seem to have been maintained well by the previous owners, so we've had a number of issues that were hard to identify.) We've always had Justin out to work on our units and he gets top marks for being consistently honest, professional, knowledgeable, and overall great.
He always explains the problem in a way that makes sense (as the female half of the household, I've several times been disappointed by other companies talking to my husband about home services as if I wasn't in the room, even if I've been the primary point of contact - Justin always treats me with as much respect as he does my husband, and I've been very impressed by that).
He lays out a couple of options for how to solve the different problems we've had with our units so we can decide what solution makes most sense for us. TL;DR: Highly, highly recommended - homeowners should thank their stars for finding him, and WF Smith should know they're lucky to have him as an employee!

This is a preliminary review! They were recommended by the maker of my A/C unit that's on the house that I just purchased. I had called the company that had initially installed and was given the run around. When I finally talked to one of the technicians, he was incredibly rude and kind of an ass. I finally called the manufacturer and was told MF was the best in my area.
I talked to a lovely woman immediately and was told that I was on the list. I figured it would be a couple of weeks. I got the phone call this morning and they were there in under 20 minutes. The technician was polite and let me know what was needed and that the unit was still under warranty. Great service! Highly recommended.
