"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

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.

Look up your model number online to find additional information. Usually, you can just take a look at the old filter and find the brand name and dimensions to order a new one. When replacing the filter, always check that it’s pointed the right way to match the direction of your airflow. Many filters have arrows on them to help with this step.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.
