Frequently Asked Questions
My AC just stopped working on the hottest day of the year. What should I do, and how fast can Lopez HVAC get here?
First, check your thermostat settings and circuit breaker. If those are fine, give us a call immediately. We prioritize emergency AC repairs in Sherman, especially during heatwaves, and will do our best to dispatch a technician to you the same day to restore your cooling as quickly as possible.
Could a faulty thermostat be why my HVAC system in Sherman is acting erratically?
Absolutely. Wiring problems in older thermostats are a common issue in our area and can cause short cycling, failure to turn on, or inconsistent temperatures. During a maintenance visit or repair call, our technicians will inspect your thermostat's wiring and calibration to ensure it's communicating properly with your HVAC system.
How can regular maintenance from a local company like Lopez HVAC prevent a major AC failure?
Our Sherman-specific maintenance service includes cleaning coils, checking refrigerant levels, inspecting electrical components, and tightening connections. This proactive care identifies small issues—like a weakening capacitor or a minor refrigerant leak—before they lead to a complete system failure during a critical heatwave, saving you from emergency repairs and discomfort.
