Frequently Asked Questions
Answers to the most common questions we hear from homeowners.
Yes. For calls received before 2:00 PM, we dispatch a licensed technician to Du Bois the same day. For after-hours and overnight emergencies, our 24/7 dispatch line is (855) 938-6364. Our average on-site arrival time in the Du Bois area is under 2 hours.
Yes. HVAC Master Pros offers financing options for qualifying customers in Du Bois on new system installations. We work with several lending partners to offer low monthly payments — ask your technician or dispatcher about current terms and approval requirements when you call.
First, check that your thermostat is set to Heat and the temperature setpoint is above the current room temperature. Replace the air filter if it's dirty — a clogged filter causes many furnace shutdowns. Check that the furnace power switch and circuit breaker are on. If the unit still won't run, call HVAC Master Pros at (855) 938-6364 — our Du Bois area technicians respond to heating emergencies 24/7.
AC repair costs in Du Bois typically range from $150–$600 depending on the failed component. A capacitor replacement runs $150–$250, a blower motor is $300–$500, and a refrigerant recharge starts at $250+. HVAC Master Pros provides a flat-rate written quote before any work begins — no surprise charges.
Yes. Our EPA 608-certified technicians in Du Bois use electronic leak detectors and UV dye tests to locate refrigerant leaks with pinpoint accuracy. We braze and seal the leak, pull a deep vacuum on the refrigerant circuit to remove moisture, then recharge to the exact factory specification by weight. We never simply "top off" refrigerant without locating and fixing the source of the leak.
Quick Self-CheckTry These 3 Things
Try These 3 Things
Before You Call
About 1 in 3 service calls in Du Bois can be resolved in minutes with these free checks. Save yourself a visit — or confirm you genuinely need a tech.
1
Check & Clean the Filter
A clogged air filter is the #1 cause of poor cooling. Pull it out, rinse under warm water, let it dry, and reinstall. Takes 5 minutes and fixes ~30% of calls.
2
Check the Circuit Breaker
AC units draw high current. Check your breaker panel for a tripped breaker. Flip it fully off then back on. If it trips again immediately — stop and call us.
3
Check the Thermostat Setting
Make sure the unit is set to COOL (not FAN only) and the temperature is set lower than the current room temp. Sounds obvious — but it's a common one.
Still Not Working?
If none of the above fixes it, there's an internal issue — refrigerant leak, failed capacitor, or burned motor. Our techs diagnose it fast and give you a flat-rate quote before touching anything.
