Signs You Need HVAC or Thermostat Repair
Your thermostat and HVAC system work together to keep your home at a comfortable temperature. A problem with your thermostat may cause your heating or cooling system to run constantly, short cycle, or not turn on when you need it. Our NATE-certified HVAC technicians have decades of experience identifying and diagnosing problems with HVACs, heat pumps, boilers, furnaces, thermostats, and more. We can work on all make and models and find answers fast. Here are some of the most common signs you need to repair AC, heating, or thermostat systems in your home:
- No airflow from your vents or very weak airflow
- Air that isn’t cooled or heated properly
- Hot or cold spots throughout the house
- Increases in your heating or cooling costs
- Increased humidity or condensation in the home

- Strange new noises from your system

Importance of Preventive Maintenance and Timely Repairs
Scheduling regular inspections and preventive maintenance allows you to identify problems before they get bigger. When our technicians perform a seasonal tune-up on your system, we will inspect each component for signs of damage, wear and tear, and problems. We will cycle through all settings to make sure they are functioning properly. We will clean and lubricate parts, replace refrigerant, and replace filters. If we catch a problem, it can often be repaired faster, easier, and for less money than if it were ignored for months.
Timely repairs are also crucial to preserving the lifespan, safety, and efficiency of your system. If you ignore a problem, it will only get worse. We can identify and fix it promptly so that you don’t have to worry about an HVAC breakdown or premature HVAC replacement.
