"After being ghosted by several AC companies we were thrilled to have Behold answer their phones, make and keep appointments, and show up for the install. Our 1970s house is blazing hot upstairs in the summer, and after considering several options we settled on a mini split. It was installed today and our bedroom is delightfully cool. Both guys on the job were professional and courteous. They kept us appraised of what they were doing and showed us how everything worked at the end of the day. They have also promised to file all applicable rebates."

"I recently had Comfair Heat and AC install a new furnace, and I couldn’t be happier with the experience. From start to finish, the team was timely, professional, and incredibly friendly. They showed up exactly when they said they would, walked me through the process, and completed the installation efficiently without cutting any corners. Their pricing was very fair compared to other quotes I received, and the quality of their work truly stands out. The new furnace runs perfectly, and the difference in comfort is noticeable already. Overall, Comfair delivered fantastic service, and I highly recommend them to anyone needing heating or AC work. I’ll definitely be using them again in the future."

"Tony was very easy to work with and accommodating. I had narrowed my choice to 3 firms. Elevation was not the cheapest nor the most expensive but I felt most comfortable with Tony and believe he offered the most value. My air conditioner was installed today, I hope this will be the start of a great (and cool) relationship."

The system has worked amazingly well and has been reliable ever since. We had a great experience with the installation and would definitely recommend 1st Action to anyone looking for quality HVAC work and a company they can trust!"

Air Conditioning questions, answered by experts

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

There are plenty of different not-so-great sounds to hear from your air conditioning unit, like squealing, grinding, water running, excessive gurgling, banging, and clanking. Each of these sounds can indicate a different malfunction with your unit, so it’s important to have a professional assess the problem before it gets worse.

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.
