Prime ac was the only company that showed up on time, performed a full evaluation and had the quotes ready same day. Install was done the next day and everything went great.

"Not only is David highly skilled in resolving HVAC issues, but he was a pleasure to work with and taught me a lot! He was punctual, communicative and patient, taking the time to explain what the issues were (in plain English), and in the end solved my A/C problems much faster AND cheaper than the so called “best in town” HVAC company I was working with. Highly recommend, and will be calling him back again!"

"Metro Air did an excellent job! I highly recommend this company, especially Ron, my technician. At first I thought i just needed Freon , then thought it was a bad capacitor, come to find out I needed a whole new outside unit. The price was on the higher end of the spectrum when I googled comparable pricing, however the customer service I received was excellent. All care was kept in keeping my home, inside and outside, clean and tidy. Ron was prompt and pleasant to work with. They work on Sundays, and came out immediately when I called with my air troubles. Great company! Thank you Metro Air!"

"Strongly recommend getting an energy audit completed on your home, especially when it's complimentary, thank you, Paul! There were quite a few items that needed attention in our home. The technicians Justin and Fernando were solid. They arrived on time, did a great job, were polite, and were very clean. They took before and after pictures, which shows how much I needed the work done. We went with the insulation to ensure it was at least 18 inches, the duct sealing of the junction boxes and HVAC unit, and we had to reroute the bathroom vent. We even did the optional UV-C light, which makes us feel much safer and takes a load off, especially in this current environment of being conscious of germs and all. Great technicians, great company, and solid work. Highly recommend Justin and Fernando :) The email and text reminder game is on point."

Heating and Air Conditioning FAQs, answered by experts

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.

Yes. Getting a whole-house dehumidifier can help you save money on energy bills. How? Your home automatically feels cooler when there’s less humidity in the air (“It’s the humidity that gets ya!” is such a true statement). This means that you won’t need to run your AC as much as you would if you had all that extra humidity in your home.

You can air condition your Arizona room by extending your home’s existing HVAC system or adding a ductless mini-split system. Arizona rooms that have full windows rather than screens only are a better choice for air conditioning—screens will let the cold air out as fast as the air conditioner can make it. 

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.
