"Mike and Jared are very professional and knowledgeable about cleaning the HVAC. Our old house had lots of coal dust from years ago and they were able to blast it out in just a few hours. Air quality improved 100%. Would highly recommend them and hire them again without a doubt."

"Mr. JONES came to our home and helped us with options on Mini Split HVAC unit for a room addition. We could not have happier with the customer service and the installation crew. He also looked at our unit for the house and gave us some future options, no high pressure sales tactics. Going to call him next year about our master bathroom remodel when we have the extra money. We are glad we found him. Give him a call you won't be disappointed."

"We recently had the pleasure of working with Mountain Comfort Heating & Air and I can confidently say this was one of the best service experiences I’ve ever had. Owner Josh Jenkins is the definition of professionalism, knowledge, and integrity in the HVAC industry. From the moment he arrived, it was obvious he truly understands his craft at an expert level. Josh took the time to thoroughly diagnose the issue instead of rushing to a quick fix like many companies do. He explained everything clearly, answered every question with patience, and made us feel completely confident in the work being performed. His attention to detail, workmanship, and pride in what he does are absolutely exceptional. What really sets Josh apart is not just his technical ability, but the way he treats people. He genuinely cares about his customers, their comfort, and doing the job the right way the first time Thank you Josh!"

Heating and Air Conditioning questions, answered by experts

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

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.

If there’s a freon leak in your home’s AC unit, it will cause the system to work overtime to cool the house. That issue will result in higher energy bills and it will take much longer for cool air to disperse throughout the home. If your system has a freon leak during the summer, it can make hot days miserable. That’s why it’s important to hire an HVAC professional to resolve a freon leak as quickly as possible.

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

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.
