FAQ
Frequently Asked Questions
Answers to the most common questions we hear from homeowners.
Yes. Our EPA 608-certified technicians in Horizon City 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.
We service all major HVAC brands in Horizon City, including Carrier, Trane, Lennox, Goodman, Rheem, Daikin, York, American Standard, Bryant, and Heil. Our technicians carry the most common parts for these brands on their service vehicles for same-day repairs.
Our Horizon City maintenance visits include: chemical condenser coil cleaning, refrigerant pressure measurement, electrical connection tightening, blower wheel inspection, condensate drain flushing, thermostat calibration, and a full written report. We do not just swap the filter and leave — every point on our 21-item checklist is completed on every visit.
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 Horizon City area technicians respond to heating emergencies 24/7.
Yes. HVAC Master Pros offers financing options for qualifying customers in Horizon City 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.
Quick Self-CheckTry These 3 Things
Try These 3 Things
Before You Call
About 1 in 3 service calls in Horizon City 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.
