To keep your heating and cooling system running efficiently, we recommend servicing your HVAC unit at least once a year—ideally before summer for AC and before winter for heating. Regular maintenance helps prevent costly breakdowns, improves efficiency, and extends the lifespan of your system.

Frequently asked questions
Why is my HVAC system running but not heating or cooling properly?
If your system is running but not keeping your home comfortable, it could be due to a dirty air filter, refrigerant leak, thermostat issue, or blocked vents. Try checking and replacing the air filter first. If the problem persists, it’s best to schedule a professional inspection to diagnose and fix the issue.
How do I know if I need a new HVAC system?
If your system is over 15 years old, frequently needs repairs, struggles to maintain temperature, or causes high energy bills, it may be time for a replacement. A new, energy-efficient system can lower your utility costs and keep your home more comfortable year-round. Our team can assess your system and recommend the best option for your needs.
