Keyko - Dover Foxcroft's Professional HVAC Repair

Yes, gas-powered water heaters and furnaces can be sources of carbon monoxide (CO) if they are not properly vented or maintained. A common sign is soot around the appliance or a yellow burner flame instead of blue. Keyko's installation and repair services ensure your water heater is correctly vented and operating safely. We also recommend regular inspections, especially before the heating season, to check for cracks or blockages in the venting system that could allow CO into your home.

In our climate, pipes in unheated spaces like crawl spaces are prone to freezing. A recirculation pump keeps hot water moving through your pipes, significantly reducing the risk of freezing and the potential for costly bursts and water damage. For Dover Foxcroft homeowners, it also means instant hot water at the tap, saving water and increasing comfort. Keyko specializes in installing and repairing these efficient systems, helping you protect your plumbing through the winter.

First, turn the system to 'off' at the thermostat to prevent damage. Ice buildup often indicates an airflow problem (like a dirty filter) or a refrigerant issue. Do not chip away at the ice, as this can damage the delicate fins. The safest step is to call Keyko. Our HVAC professionals can safely thaw the unit, diagnose the root cause—whether it's a blocked drain line or a mechanical fault—and perform the necessary repair to get your heat running safely and efficiently again.
