FAQ
Frequently Asked Questions
Answers to the most common questions we hear from homeowners.
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 Sierra Madre area technicians respond to heating emergencies 24/7.
The best time to replace your AC in Sierra Madre is during the shoulder seasons — late fall or early spring — before the peak summer demand hits. During peak summer, equipment lead times are longer and installation crews are heavily booked. Replacing in the off-season often means faster scheduling, no emergency premiums, and more time for the installation team to work without rushing.
Yes. Our EPA 608-certified technicians in Sierra Madre 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.
In most climates like Sierra Madre's, we recommend one AC maintenance visit each spring before peak cooling season and one heating system visit each fall before cold weather arrives. Areas with high humidity or heavy pollen may benefit from twice-yearly coil cleanings to maintain peak efficiency and prevent mold growth inside the air handler.
Yes. For calls received before 2:00 PM, we dispatch a licensed technician to Sierra Madre 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 Sierra Madre area is under 2 hours.
Quick Self-CheckTry These 3 Things
Try These 3 Things
Before You Call
About 1 in 3 service calls in Sierra Madre 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.
