"This was the worst experience i have ever had with a company. They came and damaged my house and kept us without AC for days. They admitted to the extensive damage and went weeks before attempting to repair it. The services were never fully completed and they were paid over 90% of the job. I disputed the last 10% and provided overwhelming evidence of their negligence. And after a year their last ditch effort was to send collections letters. Don't walk, RUN from this company. I will provide pics and my my experience to anyone who is planning on using this company. Used to be family owned and was amazing. Second they sold it went downhill fast."

"They installed a minisplit cooling system, with 3 exchanges June 2021. Since then it is not operating the way it should. In my bedroom with the door closed at night on cool at 70 degrees the humidity goes up to 80%. I wake up uncomfortable, change it from cool to dry mode. The humidity will go down into the 50% range but the temperature drops down to 62 or less! So in cool or dry mode I can't get a good nights sleep! They come and look at it and tell me everything is fine. I'm going to buy a window air conditioner tomorrow which seems insane because i spent $10,000 on this minisplit AC system!"

Heating and Air Conditioning questions, answered by experts

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

Yes, mini split systems cool equally as well as central air. While a central system circulates air throughout the entire home at the same temperature, a mini split system allows each room to be cooled or heated at different temperatures based on your own preferences. Hire a HVAC professional to determine which type of system is best for your home.

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.

Poor cooling, unusual noises, or frequent cycling are indicators that professional service is needed.

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.
