Common HVAC Problems We Fix

Thermostat Issues

Thermostat problems are among the most common HVAC issues. We diagnose and repair faulty thermostats, incorrect wiring, calibration problems, and compatibility issues. We also install and program smart thermostats for better comfort and efficiency.

Airflow Problems

Poor airflow can result from dirty filters, blocked ducts, faulty blower motors, or closed dampers. We inspect your entire system to identify and resolve airflow issues, ensuring even heating and cooling throughout your home.

Electrical Problems

HVAC systems rely on complex electrical components. We safely diagnose and repair electrical issues including faulty wiring, tripped breakers, blown fuses, capacitor failures, and control board malfunctions.

Refrigerant Leaks

Refrigerant leaks reduce cooling efficiency and can damage your compressor. Our EPA-certified technicians locate leaks, make repairs, and properly recharge your system with the correct refrigerant type and amount.

Ignition and Flame Problems

Furnaces and boilers can experience ignition failures, pilot light issues, or flame sensor problems. We diagnose and repair all types of ignition systems including standing pilots, hot surface igniters, and electronic ignition.
