Hero Background

Air Conditioning Service in Longmont, CO

Keeping your home or light commercial space comfortable year-round in Longmont requires HVAC service tuned to local weather and building conditions. With hot, dry summers, significant temperature swings between day and night, and occasional high-pollen seasons, timely air conditioning installation, repair, and maintenance is critical to reliable cooling, efficient operation, and healthy indoor air.

Air Conditioning Service in Longmont, CO

Common air conditioning issues in Longmont homes and light commercial spaces

Longmont’s climate and elevation can exacerbate several AC problems. Typical issues we diagnose and fix include:

  • Poor or weak cooling: often caused by low refrigerant, restricted airflow, clogged coils, or incorrect system sizing.
  • Short cycling: frequent on/off cycles that reduce comfort and increase wear, commonly due to oversized equipment, thermostat faults, or refrigerant issues.
  • Frozen evaporator coil: usually a sign of airflow restrictions or low refrigerant and more likely during dusty, dry conditions.
  • High energy bills: dirty filters, failing components, or aging systems lose efficiency and drive up utility costs in summer.
  • Noisy or vibrating equipment: loose panels, failing bearings, or unbalanced fans create disruptive noise and indicate mechanical wear.
  • Uneven cooling and hot spots: duct leaks, poor insulation, or improper zoning can leave rooms uncomfortable.
  • Thermostat and control failures: calibration, wiring, or smart control integration problems affect system response.
  • Refrigerant leaks and environmental compliance: requires qualified handling and EPA-compliant recovery.

  2. Instrumented diagnostics: measure airflow, static pressure, refrigerant pressures, electrical loads, and thermostat operation.
  3. Problem prioritization: safety issues and damage-limiting needs are addressed first; less urgent items are scheduled with options.
  4. Transparent options: technicians explain repair choices, efficiency trade-offs, and replacement considerations so you can decide with confidence.

Testimonials

Neighbors trust Quality Heating & Air for honest work and fair pricing.

Fred was great! He was friendly and informative, answered all of our questions and even got along with our cat (also named Fred). Would highly recommend!
Sadie P.
Really happy with my overall experience. They worked neatly, quickly, and taught me MUCH along the way. Gave great advice, helped me with a side concern, that was holding me up; and finished in time for my Dentist visit. I would highly recommend this business, and the price was a pure blessing. GREAT local company and I wasn't bribed for my review 🙃 thx guys!
Bonnie B.
Fred was very knowledgeable, he repaired an old rusted iron pipe that was part of the original house build. I thought the repair would be more costly than what Fred qouted me including parts and labor. Fred made the repair after 5pm, after getting the necessary parts and he was very clean because he put down a cloth on the bathroom floor while working. I would highly recommend Fred for service in the future and I will use Quality's services again in the future.

Great service, Fred was able to show up the same day we had a problem and get everything fixed. Very knowledgeable and did not pressure us to spend money we didn’t need to spend. I would recommend to a friend without question.

Fred Gottschalk performed a miracle with the furnace. He is by far the most knowledgeable HVAC professional I know to date. He knew everything about my furnace and replaced an old blower. The blower is far superior over the OEM one. I did the right thing choosing Fred!
Marty P.
I had an amazing experience with Fred Gottschalk! From the moment he came in to the moment he left he was very personable and made me feel good about my decision to call this company for assistance. I love the fact that they prioritize a personal touch making sure whoever comes to your door will remain your tech every time you call in. One thing he told me that gained my trust is that he will take care of my furnace the way he would want someone to take care of his granny’s. Thank you Quality heating and air, and thank you Fred!
