HVAC Repair Charleston ME | Call Northern Temp

Some frost is normal during a defrost cycle, but heavy ice buildup often signals an issue common in our climate, like low refrigerant or a faulty defrost control. It's time to call if the ice doesn't clear periodically or covers the entire unit. We can diagnose the specific cause—often related to our cold, damp winters—and perform the necessary repair to restore efficiency and prevent damage to your system.

Our comprehensive building energy audit is a detailed assessment of your home's efficiency. We inspect insulation, air leaks, windows, and, crucially, your HVAC system's performance. Using tools like blower door tests, we pinpoint where you're losing conditioned air and money. The result is a clear, prioritized report with recommendations—from sealing drafts to system upgrades or geothermal options—to improve comfort and reduce your energy bills year-round.

We recommend professional maintenance twice a year: in the fall for your heating system and in the spring for cooling. This seasonal tune-up is vital in our climate. It ensures safe operation, catches small issues before they become major repairs (like those causing short cycling or ice buildup), and maintains peak efficiency. Regular maintenance extends your system's lifespan and helps keep your energy costs predictable.
