What's included in your HVAC maintenance service?

Our maintenance service covers everything your system needs to run efficiently and reliably. We clean and inspect all components, check refrigerant levels, test electrical connections, replace filters, and calibrate your thermostat. We also look for potential problems before they become expensive repairs. You’ll get a detailed report of what we found and any recommendations for keeping your system in top shape.

How do I know if my HVAC system needs repair or replacement?

Several signs indicate your system needs attention. If your energy bills have increased significantly, some rooms are too hot or cold, or you hear unusual noises, it’s time for a professional evaluation. Systems over 10-15 years old that need frequent repairs might be better replaced. We’ll give you honest advice about whether repair or replacement makes more financial sense. Our diagnostic process identifies the root cause of problems so you can make an informed decision about your system’s future.

What should I do if my heating system stops working completely?

First, check your thermostat settings and make sure your circuit breaker hasn’t tripped. If those aren’t the issue, call us for emergency service. Don’t attempt to repair heating equipment yourself, as this can be dangerous and might void warranties. While waiting for our technician, you can close off unused rooms to conserve heat and ensure your family stays warm. We carry diagnostic equipment and common repair parts to resolve most heating emergencies quickly, getting your system back up and running as soon as possible.
