FAQs

My AC in Gaithersburg keeps turning on and off quickly (short cycling). Can you fix this?

Absolutely. Short cycling is a common issue here, often caused by a dirty evaporator coil, low refrigerant, or an oversized unit. Our repair service includes a full system inspection to pinpoint the exact cause. We'll clean the coils, check refrigerant levels, and ensure all electrical components in your HVAC system are functioning correctly to restore normal, efficient operation and prevent wear and tear.

Could an electrical problem be causing my HVAC system to malfunction?

Yes, frequently. Faulty wiring, a tripping circuit breaker, or an outdated electrical panel can prevent your HVAC system from receiving consistent power, leading to issues like short cycling or failure to start. Our electricians can perform a comprehensive electrical inspection, repair your panel or breakers, and ensure your home's wiring safely supports your heating and cooling equipment.

How does regular HVAC maintenance help with Gaithersburg's common coil and efficiency issues?

Our preventative maintenance service is specifically designed to combat local problems. We thoroughly clean the evaporator and condenser coils, which are prime culprits for reduced efficiency and short cycling. This service also includes checking electrical connections, calibrating thermostats, and inspecting the entire system. Regular maintenance keeps your unit running smoothly, improves indoor air quality, and helps avoid costly emergency repairs down the line.
