How Often Should I Service My HVAC System?

It’s recommended to service your HVAC system at least twice a year—ideally in the spring and fall. Regular servicing helps identify potential issues early, ensuring your system runs smoothly and efficiently. During these check-ups, our technicians at Donmar Heating, Cooling & Plumbing ensure everything from the thermostat to the filters is in optimal condition. This routine maintenance not only extends the life of your system but also enhances its energy efficiency, which can significantly lower your utility bills.

Common signs that your HVAC system may need repair include unusual noises, inconsistent temperatures, and higher energy bills. If you notice spikes in your energy costs without any added usage, it might be an indication your system isn’t running efficiently.
