"Patrick Andrews did an excellent job. He was friendly and very professional. He explained everything as he went. Took pictures so he could compare if it is needed next check up time. We have used Extreme heating and air for years and wouldn't use anyone else. Thank you Pat for making sure our heating unit is what it should be."

"It was such a relief to be able to fix our AC the same day without hassle. ECO tech Michael came around 8 pm after a long day. He was professional, not in a hurry to finish and leave. Took the time to explain what the problem was and the recommendation to fix the problem. Thank you for a job well done."

"I would definitely recommend Advanced the cleaning services because they are fantastic. Well worth the money which was not expensive it goes by how big your home is. But I got to see for myself the pictures of how bad my air ducts were so dirty. The owners before me never clean their air ducts, so I was breathing in all that dirt and dust, and all that stuff was nasty. After it was cleaned, he showed me the pictures of it, and I was amazed of the Difference, well worth the money definitely recommend them they were on time and the fact they were early and it was great and I am on the schedule to be done in another year because I have animals that live in the home. It smells so much better they put a sanitizer which also keeps mold, mildew down you would want to have clean air in your home."

"Riley did a great job on a new gas furnace and air conditioner install. I was very impressed from start to finish. He was on time, professional and answered every one of my questions. My system was about 15 years old and I have had to put some money into over the years. I used several other companies during that time and none of them, I mean absolutely none of them, compared to the process I just went through with TrueTemp Heating and Cooling. Everything from the service call, to the consultation process and the installation of my new HVAC equipment was top notch. Can?t recommend this experience enough! Thanks TrueTemp!"

"It was good. I told them that the air conditioning unit was making noise but I don't think that was addressed. They just did the tune-up. They were on time."

"This company is fantastic. I had a mess in a home we bought to rehab. These folks cleaned the ducts, but saved me $4,000+ dollars on various things they found that were serious issues, that were not related to the ducts. Even found a place where a previous installer for my water heater set me up for a fire. These folks are fantastic. $700 cleaning, $3300 saved!!!!"

Air Conditioning questions, answered by experts

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork. 

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

No, you should not attempt to replace an AC evaporator coil yourself. This is a complex task that must be performed by a licensed HVAC technician. The process involves handling hazardous and flammable refrigerants, which poses significant safety risks. Attempting a DIY replacement can also cause further damage to your HVAC system and will likely void its warranty. It is necessary to hire a local AC repair professional for this job.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.
