Common Questions About HVAC & AC Service
The questions homeowners ask most when searching for a local HVAC company.
How fast can you get to me?
We offer same-day service on most calls and emergency dispatch for urgent situations. For priority calls in our service area, we typically arrive within 2–4 hours.
What’s included in the $100 AC tune-up?
Condenser coil cleaning, refrigerant level check, electrical component inspection, thermostat calibration, drain line flush, and a full system test. Normally $199 — limited time offer for new customers.
Should I repair or replace my AC?
If your system is under 10 years old and the repair is reasonable, fixing it usually makes sense. For systems 12–15+ years old with major failures, replacement often pays for itself in energy savings. We give honest advice — no pushy upsells.
Do you service boilers and radiant heat?
Yes — boiler service is one of our specialties. We repair and install hot water boilers, steam boilers, and radiant systems of all types, including older cast iron systems.
Do you offer emergency HVAC service?
Yes. HVAC emergencies don’t wait for business hours. We dispatch fast for urgent situations — complete system failures, no heat in winter, no AC in summer heat waves.
Are you licensed and insured in Colorado?
Absolutely. Blue Collar Heating and Air is fully licensed, bonded, and insured in Colorado. All technicians are certified and we pull permits for any work that requires them.
