The Problem
Small Problems Become Expensive Problems
Most HVAC breakdowns don’t happen out of nowhere. They start as minor issues — a dirty filter, a worn belt, a low refrigerant charge — that go unnoticed for months until something fails at the worst possible time.
Regular tune-ups catch these problems early. A $150 maintenance visit is a lot easier on your budget than a $1,500 emergency repair on a Saturday night.

What We Do
What's Included in a Tune-Up
Every tune-up ends with a written report on your system’s condition, any issues found, and recommendations — prioritized by urgency so you can make informed decisions.
Cooling System Tune-Up
Spring/summer service: check and adjust refrigerant levels, clean condenser and evaporator coils, inspect and tighten electrical connections, test capacitors and contactors, lubricate moving parts, check thermostat calibration, inspect condensate drain line, measure airflow and temperature differential, and replace standard air filter.
Heating System Tune-Up
Fall/winter service: inspect heat exchanger for cracks or corrosion, test ignition system and safety controls, check gas pressure and burner operation, inspect flue and venting for proper draft, test carbon monoxide levels, lubricate blower motor and bearings, check thermostat operation, inspect electrical connections, and replace standard air filter.

Maintenance & Tune-Ups — Common Questions
What homeowners ask about keeping their HVAC system running efficiently year-round.
How often should I have my HVAC system serviced?
At minimum, once a year. Ideally, twice — once for cooling (spring) and once for heating (fall). This catches seasonal wear before you’re relying on the system daily.
How much does an HVAC tune-up cost?
What's the difference between a tune-up and a service agreement?
Will a tune-up lower my energy bills?
Usually, yes. Dirty coils, low refrigerant, and clogged filters all force your system to work harder. Correcting these issues typically improves efficiency by 5–15%, which shows up on your monthly bills.
My system seems fine — do I still need a tune-up?
Do you service all brands?
Yes. We service every major residential HVAC brand — Carrier, Lennox, Trane, Rheem, Goodman, Daikin, Mitsubishi, and more. Regardless of who installed it, we can maintain it.
