"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

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance

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.

To lower humidity quickly, run a dehumidifier or your home's air conditioner or turn on exhaust fans to extract moisture. These methods can quickly and effectively bring your home's humidity levels to a comfortable condition. However, you should consistently practice humidity-reducing tasks to maintain proper indoor humidity levels.
