"I had some backup into the basement, they came to rod it out and told me I needed to check the line going to the street and they could come back for a video check. Well they said they came back and took the video and I needed some expensive work to clear the line. I called to ask them for the video, they said that they'd have someone call me back. They called me back and said that there was no video, their worker didn't put in a USB drive and besides they said I didn't ask for one. What did they expect I was asking for??? I said I expected and wanted a video, how do I know they even really performed the work. They said they would call me back. THEY DIDN'T. I called them back, they again said they'd call me. Again no call. The last time they told me, the owner was on another call but would definitely call me back. One week later NO CALLBACK. I firmly believe they didn't do a video, charged me for one and took me for a sucker. I will NEVER use this company again. I think they are crooks. P.S. Ever since they rodded the drain one of my toilets started have trouble flushing. I won't doubt they messed it up so they could come back again for more money. DO NOT USE. P.P.S. I wonder if they will contact me on this posting, I doubt it."

"Thermatech was the very first company to respond when I reached out on Angie's List I booked them to come out and give me an estimate when the tech arrived about 2 hours later he found that the control board had caught fire and some parts needed to be replaced initially the estimate I thought was a little on the high side so I was going to get another quote how about 30 minutes later I got a call from the office stating that they found the parts cheaper and gave me a another quote which I found to be very reasonable and I booked them to do the job the very next day they were there in the afternoon and fixed my furnace I am very happy with their service and their pricing was very reasonable I would recommend them the tech Jeremy was very efficient and very nice"

Heating and Air Conditioning questions, answered by experts

The first sign you're not getting enough return air is if some parts of your home feel hotter or colder than others. If nothing else is causing that, leaky air ducts are your next clue. If the air pressure feels different in every room, this is also usually a sign of insufficient return air.

Though it may seem redundant, you can absolutely have a central AC unit and a window AC in your home. In fact, if you place a window AC unit near your central air, it can help move the cooler air throughout your home. But doubling up on your AC methods can get pricey, so factor in cost accordingly.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.

If you have the luxury of waiting a bit to replace your unit, they can drop in price depending on the time of year. Air conditioning units often go on sale in the fall after they’re not as in demand when the temps drop outside. Same with furnaces—prices drop in the spring when it starts getting warmer.

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.
