Heating Maintenance

In Jacksonville, heaters sit dormant for 10 months. This inactivity leads to dust accumulation, seized valves, and electrical corrosion. We provide specialized maintenance to ensure your system is safe, efficient, and ready when the temperature drops.

Featured Project: The 'Frozen' Heat Pump Rescue

A Mandarin homeowner found their unit encased in a thick block of ice. We identified a failed defrost board and corroded sensors. By de-icing the unit and calibrating the defrost timing, we restored vent temps from 68°F to a toasty 98°F and prevented a massive JEA bill spike.

The Pro’s Advice

“Expert tips to avoid a 'First Freeze' emergency.”

01

The October Test: Turn your heat on for 20 mins in October with windows open to burn off dust before it gets cold.

02

EM Heat Warning: Use 'Emergency Heat' ONLY if the pump is broken. It's 3-4x more expensive than standard heating.

03

The 2-Foot Rule: Keep fallen leaves and winter weeds 2 feet away from your outdoor unit so it doesn't ice over.

04

Listen for the Buzz: A persistent buzz can mean a failing contactor or a struggling reversing valve. Catch it now.

Questions?

“Everything you need to know about keeping your home comfortable.”

Dust settles on the 'heat strips' during 10 months of idleness. It usually burns off in 20-30 minutes. If it persists, turn it off and call us.

Light frost is normal. Your system has a 'Defrost Mode' to melt it. However, if it's a thick block of ice that won't melt, your defrost board has failed.

Heat pumps blow air at 85-95°F. Since your body is 98.6°F, it can feel cool, but it's still heating. If it's the same temp as the room, the reversing valve is likely stuck.

Yes. Florida's salty air corrodes connections while they sit idle. Maintenance prevents electrical fires and 'sticker shock' utility bills.

We clean the heat strips, test the defrost cycle, tighten high-amperage electrical connections, and calibrate your thermostat for heat pump efficiency.
