General HVAC Questions

Why is my air conditioner or heater not working properly?

There are several reasons why your AC or heating system may not be working efficiently, including:

  • Clogged air filters restricting airflow
  • Low refrigerant levels in AC units
  • Thermostat malfunctions
  • Blocked vents or duct leaks
  • Worn-out or faulty components

If you notice uneven cooling/heating, weak airflow, strange noises, or an unexplained increase in energy bills, it’s time to schedule a professional HVAC inspection. Our Aurora HVAC technicians can quickly diagnose and fix the issue to restore comfort to your home.

How often should I have my HVAC system serviced?

For optimal performance, your heating and cooling system should be professionally maintained:

  • Air Conditioners – Once per year (preferably in the spring)
  • Furnaces – Once per year (preferably in the fall)
  • Heat Pumps – Twice per year (spring and fall)

Regular maintenance extends the lifespan of your HVAC system, improves energy efficiency, and helps prevent costly breakdowns.

How long do HVAC systems last?

  • Air Conditioners – 10 to 15 years
  • Furnaces – 15 to 20 years
  • Heat Pumps – 10 to 15 years
  • Water Heaters – 10 to 15 years

If your unit is nearing the end of its lifespan or frequently requires repairs, it may be time to consider a replacement. Our team can help you choose an energy-efficient HVAC system that fits your home and budget.


Air Conditioning FAQs

Why is my AC blowing warm air?

If your air conditioner is blowing warm air, the issue could be due to:

  • Low refrigerant levels
  • Dirty or clogged air filters
  • Thermostat settings issues
  • Frozen evaporator coils
  • Electrical or compressor problems

We offer 24/7 emergency AC repair services in Aurora, Denver, and Castle Rock, so if your AC is malfunctioning, call (720) 772-5081 for fast service.

You should consider replacing your air conditioner if:

  • Your unit is 10+ years old
  • Repairs are becoming frequent and costly
  • Your energy bills have increased significantly
  • The system struggles to cool your home evenly

Heating & Furnace FAQs

Why does my furnace smell like burning?

A burning smell from your furnace can indicate:

  • Dust burning off if the furnace hasn’t been used in a while
  • Overheating components due to restricted airflow
  • Electrical issues or wiring problems
  • Gas leaks (if you smell rotten eggs, evacuate immediately and call a professional)

If the smell persists, contact us for furnace repair services in Aurora to ensure your safety.

Why is my furnace making loud noises?

Unusual furnace noises may be caused by:

  • Banging or popping – Expansion of air ducts

Ignoring these sounds can lead to major system failures. Our Denver furnace repair specialists can diagnose and fix the problem quickly.
