Jacksonville & Duval County

HVAC Services in Jacksonville, FL

One crew, ten services, and the same promise on every one of them: you get the number before we start.

Everything we do

Heating, Cooling and Air Quality for Jacksonville Homes

Ten things, done by the same small crew, across Jacksonville and Duval County. If you are not sure which one you need, call and describe what the system is doing — most of the time we can tell you on the phone.

AC Repair

Something is broken and you want it fixed, not replaced. We find what actually failed, and you get the number before we touch it.

Emergency AC Repair

No cooling now, and someone in the house who cannot simply wait it out. We triage on the phone before anybody drives out.

See the page →
AC Replacement & Installation

For when a system is genuinely finished. Sized from a load calculation for your house rather than matched to the label on the old one.

See the page →
Heating & Furnace Repair

Heat pumps, electric strip heat and gas furnaces, for the handful of Jacksonville nights that actually ask for them.

See the page →
HVAC Maintenance & Tune-Ups

Measured, not a clipboard exercise. This is the visit that finds the weak capacitor in March instead of July.

See the page →
Heat Pump Repair & Service

The system most Jacksonville houses are actually running, working in both directions, most of the year.

See the page →
Ductless Mini-Splits

Garages, bonus rooms, Florida rooms and additions — the spaces the existing ductwork was never going to reach.

See the page →
Air Duct Cleaning & Duct Work

We put a camera in first. Often the honest answer is that your ducts do not need cleaning, and we will say so.

See the page →
Indoor Air Quality

In this climate that is mostly a humidity problem wearing a different hat. We measure before recommending anything.

Commercial HVAC

Rooftop units, split systems and light commercial work for Jacksonville businesses and property managers.

Not sure which one you need?

Tell us what the system is doing — the noise, the smell, the room that never cools — and we will tell you which of these it is. Or that it is none of them.

The same four things, whichever one you called about

1
You get the number before we start

The full price, what it buys, and why. Nothing is opened up, replaced or billed before that conversation happens.

2
We show you the failed part

The dead capacitor comes out and goes in your hand. You should never have to take our word for what was wrong.

3
We tell you when not to buy

If a repair will get you through, we will say so — even when the replacement is the bigger ticket.

4
We test it and clean up

We confirm it is actually cooling before we leave, check the drain, and take our mess with us.
