I had both plumbing and electrical people come out and the plumbing person had told me that the he…read morecould not do the service so he just charged a small fee for coming. However he did say that if there was services actually performed it would have been around $600 flat fee for basic service. I thought that was a little high for replacing a outdoor faucet and parts and so on. But he was very helpful. The electrician came out and he did a wonderful job figuring out where the problem was but for the electricians they're charging a flat fee of over $400 and to assess the problem and do basic repairs. Now he assessed the problem but he could not repair it without additional costs which he estimated to be about $1500. So I still got charged but no repairs.

Caused my working furnace to fail, the house froze, leaking pipes…read moreand they refused to make the repairs that they caused. On October 22 2025 I had Master Services perform an annual service on my Carrier furnace. The furnace was working well with no issues but I wanted to do the annual service as recommended. Morgan the technician poked around but I did not see any of the standard procedures done like I am used to seeing from other providers. There was a tremendous sales pitch pressure from the tech spending more time on how I can purchase a new furnace from their company, even though our furnace served us well and was in excellent condition. I paid the bill and he left. Oct 24 2026 just two days after service The furnace failed to start and we were in cold weather for several hours. So I called the company back asking why the furnace is having this problem right after the tech worked on it. Morgan came back and blamed it on a blown 3A purple fuse which never happened before. He said he did not have a fuse in his truck, luckily I had 3 of those in my fuse kit in my truck so I gave him my fuses, he started switching wires around burning 2 more of my fuses and finally he got the wiring right and the 3rd and last fuse worked and the furnace started to work. He did not seem sure of what is happening or what else to check for. We had to make a trip out of state to visit family but we always leave the heat on in cold weather just to be safe and we turn the main water valve off and drain the pipes. Jan 28 2026 We returned to the house to find there was no heat in the house and the toilet tank and bowl had blocks of ice in them. The bathroom sink trap was cracked from ice and the shower valve was busted along with the kitchen sink not draining. A pipe also sprung a leak in the basement. There was also a strong natural gas odor in the house. We called again and they sent another tech Mitch who showed up with three space heaters to thaw the house plumbing out but could not get furnace started he also confirmed the gas smell to be present he said the gas coupling inside the furnace was not tightened enough from when they did the first service. He did not bother to check the ignitor but did after I asked him to check it. He said the ignitor is bad and he will call me back the next day with a price as he claimed did not have a replacement ignitor in his truck and he estimated the price would be around $600 a part that cost under $30 He left us with no heat and a gas leak while I slept in the house in the extreme cold snap in January I could have died from both the cold and the gas leak. Jan 29 2026 Mitch never called back to come replace the ignitor. I gave up and had to call ANOTHER company to get our heat working. They came over and figured the problem in 5 minutes replaced the ignitor and tightened the gas coupling which was left loose by two technicians from Master Services. My bill was $357.44 and our furnace is working well since till the writing of this review March 23 2026. Jan 30 2026 Plumber Eric from Master services came over replaced the frozen sink trap that they caused to fail from freezing and charged me $154.83 He also gave an estimate of $1700 to replace the leaky pipe that they caused to freeze up due to low quality work. I refused to do this and feel they must take responsibility and fix what they broke. I had to replace the shower valve myself and get the kitchen sink flowing again. Several phone conversation with manager Juan did not help as he insisted they have to charge me for pipe repairs that would have never happened if they did not cause the freeze. My pipe is still dripping and they totally ignored the problem. I see that a Mr. Kyle Burroughs listed as general manager on the better business bureau website so Mr. Burroughs if you are reading this Please intervene to rectify this problem. You can get my contact information from your service department records. All I need now is you send a plumber to replace the pipe section that is leaking so we can put this nightmare behind us.

I called Shane early in the morning and he was able to come out the same day. He was extremely…read moreclean, super thorough, and explained everything as he went. It's one thing to be a homeowner and have people come into your home to do service, it's another thing entirely when they explain why they are doing them and help you prevent it in the future. If all you are looking for is value, I can assure you that won't be sad to have Shane come out. Super affordable and professional, you won't go wrong here. Our sewer drain was clogged and it backed up into the basement. Shane came in and explained how he was going to diagnose where the clog was, then explained how he was going to clear it. As he was clearing the clog, he explained how we can prevent the tree roots from coming back after we took the tree down. He ran the pipe in forward and reverse to make sure he cleaned out all the roots. Within 45 minutes he had the whole service done and explained the entire process as he went. You cannot ask for a better person to come in and help you when you're not sure how bad the problem is.

John was the second contractor I called, expecting a quote for repair or replacement for a problem…read moreI had already attempted to have serviced with another provider. John accomodated my availability, arrived exactly when expected, assessed the situation, made the repair, and was out the door within 30 minutes. Rather than scam my ignorance for new parts or push me to a new furnace, he simply adjusted what the previous provider had neglected address. And, the quote he provided, when the part is needed, was $1,000 less. I am officially a loyal customer who will be recommending him at every opportunity!

It took them a day to fix the problem and all the problems the other contractors had created by not understanding how old furnaces work. Comfort Air was very professional, called when they said they would, delivered estimates well within reason and market value, and delivered on their promises on time the first time. If you have an old furnace, call these guys. As a testament to how well they did fixing my old furnace, when I upgrade to a brand-new system with duct work (which my house currently doesn't have), I'll be using Comfort Air.

Nothing special per say but friendly, reasonable and while I was skeptical about the service agreement, It turned out to be a God send. Since that day, I have had multiple problems and every time they send somebody out the same day and always get it fixed. If you have the service agreement, you save a ton of money and trust me, if you live in the area, you will not find a better company. They don't make the prices up, they have listings of what things cost so it's the same price for everyone. This is my HVAC company for as long as I own my house and live in Wonder Lake.

A crew arrived at 7 A.M. and the work was completed by 6:00 P.M. We had some moldy plywood sheathing that was discovered upon removal of the shingles and they replaced them with HUD UM-40 APA 24/16 rated sheathing that exceeds code requirements for residential construction. The Atlas shingles that were installed look absolutely fantastic. Upon completion of the work, all debris was removed. We feel the work was exceptionally good and a supervisor shared images of the complete process undertaken that required 13 hours of labor. We have nothing but praise for what we experienced and for what we see as our new roof. The view from the street it's testimonial to work well done !
