Air Conditioner Repair in Denver

You rely on your air conditioner (AC) to provide cool air during the Denver summers, and when the unit starts acting up, you need reliable services. At One Hour Heating & Air Conditioning®, we will treat your property like it's our own. We provide quality air conditioner repair services in Denver and the surrounding areas, prioritizing your comfort by recommending durable solutions. 

Signs that You Need AC Repair?

Learning to recognize when your unit is struggling can help you keep your AC operating smoothly. Take a look at some common signs you need AC repair for your Denver property.

  • Unusual Sounds or Smells: Screeching, grinding, banging, or any unusual sound can mean something's wrong. Motor failure, loose components, or stuck objects are usually to blame. Foul odors also indicate a problem. Mold could be forming in the system, or the motor is overheating. Any smell compromises your indoor air quality (IAQ) and should be checked by a professional as soon as possible. 
  • Poor Airflow: Compressor issues or blocked ductwork can cause poor airflow. If your home isn't cooling properly or you're not feeling enough airflow, the unit likely needs a repair.
  • High Humidity Levels: Besides pumping in cool air, your AC should also reduce humidity levels. If you see condensation on your windows, have clammy skin, or notice a musty smell, the system isn't decreasing humidity in the air and needs expert attention. 
  • Increased Energy Costs: Dirty coils and filters, poor airflow, and refrigerant leaks can cause AC inefficiency and a spike in your energy bill. If your electricity use has remained the same, but you see a sudden rise in energy costs, ask a licensed technician to look at your unit.
  • Warm Air From the Vents: An air conditioner is supposed to pull warm air from your property, cool it, and push the cool air back in. During this process, it also expels heat from the air to the outside. When warm air comes from the vents, your ductwork may be faulty, pushing in warm air from your attic or outside. The AC could also have low refrigerant levels, and in both cases, you'll need an AC technician.

“David Brown performed our annual A/C system maintenance and did a fantastic job. He was very thorough, respectful of the property and answered any questions I had. He went above and beyond, and I asked him for his business card so I can request him for future service visits through One Hour Heating and Air Conditioning.”

“Faster appointments than the other guys, even the original installer. OneHour technician diagnosed the issue, and rather than just making a potentially expensive repair, he recommended working with the original installer under warranty to save me money. I appreciate OneHour’s prompt appointments and honesty. The other company is scheduling 4 days out, but at least we’ll have a second opinion and potential savings.”
