Maintenance

Your HVAC system is an investment. Like a car, it needs regular attention to run longer, run better and stay out of the shop.

A maintenance plan does not make failure impossible. It makes it far less likely, and a good technician catches the small problem before it becomes a dead system on the hottest day of the year.

Book a tune-up

Gold industrial blower motor inside an air handler with a flexible conduit running to it — Belts, lubrication and alignment on a big blower motor, done to the maker's schedule.

Orange manifold gauge set with blue low side and red high side dials hanging on an outdoor condenser — Pressures on the line.

Yellow Fieldpiece clamp meter measuring a blower circuit inside a furnace cabinet — Amp draw at the motor.

System diagnostics

Before anything gets replaced, it gets measured. Pressures, temperatures, amp draw, airflow. The numbers say what is wrong.

You get the answer in plain English, with the readings to back it up, so you are deciding with facts instead of a sales pitch.

Repairs

Plenty of systems can give you more good seasons if the right part gets fixed. Too often that option never gets put on the table.

Jimmy is as comfortable repairing a unit as replacing one, and he will tell you honestly which one makes more sense for your house.
