HVAC Maintenance & Tune-Ups in Marietta, GA

Seasonal tune-ups that prevent breakdowns, lower energy bills, and extend the life of your system — for homeowners across Marietta and Metro Atlanta.

The cheapest HVAC repair is the one you never need. Regular maintenance from Ultimate Home Services Plus keeps your heating and cooling running efficiently, catches small problems before they become expensive ones, and helps your equipment last as long as it should.

In our climate, systems run hard — long, humid cooling seasons and the occasional hard winter freeze. That wear adds up. A tuned system uses less energy, cools and heats more evenly, and is far less likely to quit on the worst day of the year. It also helps keep your manufacturer's warranty valid, since most require proof of routine maintenance.

Why Regular Maintenance Pays Off

Fewer breakdowns — we catch worn parts before they fail.
Lower energy bills from a clean, properly charged, efficient system.
Longer equipment life, protecting your investment.
Better comfort with more even heating and cooling.
Warranty protection — many warranties require documented maintenance.
Healthier air from clean coils and fresh filters.

What's Included in a Tune-Up

Our maintenance visits are thorough, not a quick glance. Depending on the season, we cover:

Cooling tune-up

Check refrigerant levels and inspect for leaks
Clean condenser and evaporator coils
Test capacitors, contactors, and electrical connections
Clear the condensate drain line
Calibrate the thermostat and check airflow

Heating tune-up

Inspect burners, igniter, and flame sensor
Check the heat exchanger for safety (carbon-monoxide risk)
Test blower motor and amp draw
Verify safety controls and thermostat operation
Replace or check filters and inspect airflow

When to Schedule

We recommend two visits a year: a cooling tune-up in spring before the heat arrives, and a heating tune-up in fall before the first cold snap. Getting ahead of each season is the best way to avoid an emergency call when you need the system most. Already noticing a problem? Start with AC repair or furnace repair instead.

Maintenance FAQs

Twice a year is ideal — cooling in spring and heating in fall. At minimum, service the system you're about to rely on before each season begins.

Yes. A tune-up typically costs a fraction of a major repair and helps prevent the breakdowns, high energy bills, and shortened equipment life that come from a neglected system.

Often, yes. Many manufacturers require proof of regular professional maintenance to honor warranty claims, so documented tune-ups protect your coverage.

It can. Clean coils, correct refrigerant charge, and good airflow let your system reach the set temperature with less runtime, which shows up on your bill.
