Initially I was pleased however after the first scheduled routine service, by a rival company with whom I already had a service contract, I was much less than pleased. They did no service just an overall inspection of the work Stewart's had performed. They wrote up pages of issues and took 28 photos to back up their evidence. I sent both to Stewart's in email and made an appointment, which then got cancelled due to covid isolation. Stewart's has made NO MOVE or EFFORT to make another appointment to correct the issues outlined in the report. I have sent off another email today but if no reply is forthcoming I will need to take it to the next level.

Right off the bat I wasn't thrilled because I needed two appointments. One for hvac and one for plumbing. Ok, fine... During the furnace inspection Bart found a gas leak in the flex line to the furnace. He fixed it best he could and let me know. He said he didn't have the part and he would let the office know that when the plumbing people come out the next day they can fix it. Super. Day 2 and Jason shows up and I let him know whats going on with the toilet, but no one had let him know about the gas leak. So I called the office and let the lady know what was going on and that there was apparently a miscommunication. She called Bart, who called Jason and explained what was going on. During all this back and forth Jason identified that the toilet needed to be repaired or replaced. They want $201 to repair if they even can, $553 to install a new toilet if we buy it elsewhere and $801 to buy it from them and have them install. All of the above are higher than any other quote we got from any other place we called. Unfortunately, Jason doesn't have a ladder, so he can't look at the leak. I call the office again and they can send someone back out again the next day to repair. I ask if they are going to charge me the base fee for coming back out again and she says no, but then quotes me $199 plus parts to replace the flex line. I call Sexton Heating and Air and they quote me $150 plus parts and he says that includes the base service fee. Needless to say, Sexton is coming out tomorrow. I've been using Stewart for our annual AC and furnace inspections and for all of our plumbing needs that have popped up over the last few years and after this they have lost a customer. At the very least, they lost my trust.

Response from Stewart Heating Air & Plumbing Inc
Hi [Member Name Removed], Sorry to hear about the communication issues with our Service Technician and Plumber. Unfortunately the Service Techs paperwork was turned in the next morning and not relayed to the Plumber. Normally we quote $199 per repair plus the part, before we attempt any kind of repair, I will communicate that with the Service Technician since he is still new and learning. Thank you for communicating where we need to improve. I am sorry to lose your business since we have been maintaining your furnace and AC since 2015. How can we make it up to you? Respectfully, Kathy McGlothin General Manager Stewart Heating, Air & Plumbing

Don was prompt and quick at evaluating the solution to the problem. He had the needed part on hand. Verified with me, prior to replacing the part, that I wanted to put the money towards the repair or towards a new unit since my unit was old. This occurred over the Labor Day weekend (Saturday) and I called at least 6 other companies to find someone who was available. Stewart was the only one available and provided service on Monday for a reasonable "holiday" fee.

Turns out they could have replaced the system but it wasn't cost-effective for my budget. They were super professional and punctual; even called to confirm my appointment for the quote. Sad to not use them yet, but would definitely go with them in the future.

So very professional and knowledgeable. I was given 3 price/material options and the materials and process were thoroughly explained before I committed. Can't say enough great things about the estimator (Jamie) who came out and followed the project to completion. Installers were polite and cleaned up very thoroughly. I felt safe while they were in my home. I will use Stewart for any future HVAC needs!
Description of Work: My ductwork was thoroughly inspected for leaks as air was escaping through the vents into the house. My very old ductwork was a total damaged mess. I was shown severl photos from under my house. All ductwork was replaced, vents sealed.

They did a super job. All I need is someone to come out and change the filter and check it because I have a warranty for any repairs that need to be done on my heater. I will probably go back to them to do the yearly.

That's the same people that put it in 40 years ago. He's been excellent. They handle everything they're perfect. For everything that needed to be done they do it and there's never a problem and whenever there's an outage they come right out and work until it's fixed that's why I'm on a contract with them. They're on time, they do the work and if a part breaks they're not responsible for the manufacturer of the part comes out and change it right away.

Our air conditioner broke down and I called Stewart Heating. I got their name and number off of Angie's List. The technician came to the house the next day and examined our air conditioner to see what the issue was. He advised that he could temporarily fix the unit but it was 28 years old and the item that needed fixing is not made any more and it would cost to have a part made for it. He told us about a program that allows homeowners to replace old items with energy efficient items (Hero) and asked if we would be interested in getting more details about it. In the mean time he temporarily fixed the air conditioner. Within a few days, Mr Bill Stewart came over to the house and talked to us about the program. We decided that day to go with it and Mr Stewart helped fill in the required paperwork to get everything moving. Within a week we had a date set up for the work to start. All the workers from Stewart Heating Air and Plumbing were very professional. They cleaned up after themselves every day and also took the time to explain to us what was being done. After finishing everything, took about 3 days from start to finish, they walked me through everything and how it works. They installed a new computer panel on the wall that controls the heat and air and showed me how to program everything. Since everything was installed, they have called to see how everything was working and to see if I had any questions. They have also been out just recently to check on the new systems and also to change the filter in the Air/Heater unite. After having everything replaced, the house has been much cooler in the summer and warmer in the winter. The new tankless water heater needed to have the temperature turned down a little as it got hot a lot faster than the old and a lot hotter set on the same setting as the old.
Description of Work: Replaced a 28 year old Heater/furnace with a more state of the art and energy efficient unit Replaced a 28 year old Water Heater with a tankless water heater Replaced a 28 year old Air Conditioner with a more state of the art and energy efficient unit Replace all the duct work that was old and not properly installed Added insulation in the attic as it had very little

See recap above. Avoid this contractor. Really terrible.
Description of Work: Do not use this provider. I purchased a coupon to get my furnace checked. The service person declared it dangerous and shut off the gas/electric because of an alleged cracked heat exchanger and carbon monoxide poisoning risk. He then quoted a new furnace for $3500 plus dollars. I paid for a second inspection after doing some on-line research about how you diagnose a cracked heat exchanger. It did not mesh with what I discovered. The second provider (Atlas Heating and Air) said it was not a cracked heat exchanger problem but a damper problem. The damper problem was fixed for $215.00. Hard to know if this provider is incompetent or trying to sell new furnaces. Obviously, these inspection deals are a way of providers' getting work, but misdiagnosing problems and shutting of furnaces in order to sell a new one is really problematic

Overall, Stewart's did a decent job; enough that I give them an A for the work that they did. I might consider them for further work, but only if they were in the same price range as others, after I did thorough research. The air conditioner of my central heating system stopped working just as the heat was starting to increase for the year. I used this service call to figure out what was wrong with the system. I specifically told the company that my unit was on the second floor. But I think they misunderstood; it was on the 2nd floor of an overhead crawl space, and required a ladder to access. For that reason they had to come again to actually do the check. I can say they did an accurate job of diagnosing the specific problem because I got a second opinion. I was not thrilled by the solution on they proposed, which was 1) get a repair at $300+ and/or 2) replace the furnace (~$4000). Remember the repair was for the air conditioner. They said the check revealed that the system was old (knew that), that it was rusted out, and needed replacing immediately (not quite true). Any repair would only put a bandage on a more severe problem. But then, I realized I had paid for a system check by a service company whose job it is to sell air conditioners and furnaces. I should have expected that. To end this repair story, the part they told me broke, I did have replaced, by another company for nearly half the price. The other company verified that was indeed the problem, and sure, I could get a new furnace, but I probably had at least another season with the current one. Plus the part that broke was not due to an inefficient furnace, thought it didn't help matters.
Description of Work: Provider came to dwelling (twice) to check out air conditioner. I was only charged once.

Our heater died on 1/16/16. My husband called and got an appointment for Sunday afternoon at 3pm. The technician called and said he could be early if that was convenient, which was great. He performed the diagnostic (for $89). His conclusion: "found bad board ($1,092) and spark igniter ($558). Due to age and condition of unit recommend replacing unit ($3,767)." We were also told that the price of the diagnostic could go towards the cost of service if ordered within 48 hours. My husband did some research online and discovered that the cost of a new motherboard was less than 1/5th of what we were quoted. Based on this, we decided to get a 2nd opinion. After another 30 minutes to test/diagnose, the only issue discovered was the spark igniter, which cost $97 and took about 15 minutes to replace. We were also told that our furnace was in good condition. Overall impression is that scare tactics were used to pressure us into purchasing a new unit.
Description of Work: 20 minute diagnostic.

They came out right around the purchase time. There were no extra charges. The thing that stood out about them was the individual who came was seemingly qualified for the job. It was really clear and he did make a statement that plumbing is new for Stewart Heating and Air and it's something that they recently added. Therefor he wasn't equipped to necessarily handle anything and everything plumbing related but he was professional and absolutely kind. He quickly recognized that Extra Hands, the previous person that tried to repair a fixture, a bathroom tub fixture, broke it and completely damaged it. He did recognize it and I will give it to him he did know what he was doing and did his best to repair. They were unable to fix it but it was most certainly not his fault. I would give them a B just for effort. They were courteous, great at trouble shooting, gave some suggestions as to other places we may be able to find a fixture, and honest, he just laid out the facts for me. I would use their services in the future but not for plumbing.

Our Guest Suite has an independent Heating/Cooling system. It suddenly stopped working one day. Our Home Insurance company said that this was a commercial grade unit so won't be covered under warranty. I looked up on Angie's List and contacted Stewart Heating. They sent a technician over; he was very knowledgeble and professional. It turned out that the unit was not broken and was going in defrost mode. He educated me on the unit and changed the filter that has been changed in a long time. He spent a lot of time making sure there was nothing wrong with the unit and went though all the major components of the unit. I am very happy with their service and will use them again.
