"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!"

"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."

"I asked them to check my dryer vent/hose hookup for connection. They cleaned the lines and connected the hose to the back of dryer. They also hung and readjusted the bi-fold doors to my laundry room. They both were very knowledgeable and professional in their work. I plan on having them to come back and do some more projects soon. I highly recommend this business without hesitation."

Heating and Air Conditioning FAQs, answered by experts

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

Yes, the furnace and AC use the same blower. The blower is located in the base of the furnace and pushes hot air out of the furnace and into the ducts. It also pushes cool air through the home when the air conditioning is on. Even though the furnace and air conditioning work independently of one another, the blower is an essential component for both systems.

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.

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.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.
