Air Conditioning Repair, Installation, and Replacement

From Killearn Estates to Southwood, when a Tallahassee home stops cooling, Sterling Service starts air conditioning repair by finding the cause: a failed capacitor or fan motor, a refrigerant leak, a frozen coil, or a system that has simply run its course. Your technician explains what they found and the repair and replacement options before any work begins.

Tallahassee recorded its first 100-degree day since September 2024 on July 29, 2026, and a tired system tends to give out when the heat peaks. Wherever your home sits in the city, the best time to weigh repair against replacement is before a heat wave, not in the middle of one.

Heat Pump Repair, Installation, and Maintenance

A heat pump cools in summer and heats in winter, so it works almost year-round. At Sterling Service, we repair, replace, and maintain heat pump systems, and a routine maintenance visit is how small problems get caught before they become a no-cooling or no-heat call.

If you live in Midtown or anywhere else in the city and wonder whether one heat pump could replace both your air conditioner and your furnace, we answer that for your house and your utility service, not in the abstract.

Furnace Repair, Replacement, and Installation

Tallahassee winters are short, so a gas furnace can sit idle for months and the first cold morning is when a problem shows up. We repair and replace gas furnaces, checking the ignition, flame sensor, blower, and heat exchanger, and we can tell you whether a repair makes sense or whether a new furnace or heat pump is the better move.

Ductless Mini-Split Systems

A ductless mini-split fits places the existing ductwork serves poorly: an addition, a converted garage, a sunroom, or a bonus room that never stays comfortable. We install and service ductless mini-split systems, and a technician can map out which rooms should be zoned during a visit.

Air Duct Repair, Sealing, and Duct Cleaning

Ductwork carries the air your system makes into every room, so leaks, crushed runs, and dirty ducts can undercut a good system. We test, seal, and repair ducts and handle duct cleaning when cleaning is warranted. From Betton Hills to Ox Bottom, we look at the whole duct system before recommending a fix.

Indoor Air Quality and Humidity Control

Comfort depends on more than temperature, so our technicians treat indoor air quality as part of the whole system, looking at filtration, ventilation, and humidity, then recommending upgrades that fit how the home is built and lived in.

Utility Rebates and Loans for a New HVAC System

If your electric service comes from City of Tallahassee Utilities, the City pays rebates on qualifying central air conditioners and air-source heat pumps: $100 at the Bronze efficiency level and $350 at Gold. A split-system air conditioner needs a 15.2 SEER2 rating for Bronze and 17.0 SEER2 for Gold. The rebate requires a permitted installation, a passed final inspection, and a matched system with an AHRI reference number, and the application is due within 90 days of the final inspection. The City notes that rebates can change without notice, and its program page was last updated October 20, 2026.

For the larger cost of a replacement, City Utilities also offers energy-efficiency loans from $500 to $15,000 at a 5% fixed rate, with terms up to seven years and no income requirement. Qualifying work includes air conditioners, heat pumps, gas furnaces, and duct testing, sealing, and replacement. The order matters: the loan must be approved before any work begins, every owner on the deed must be on the utility account and sign the note, and the City pays the contractor directly after the work passes inspection. Our Tallahassee utility loans page walks through the steps.

Confirm your eligibility with City Utilities at 850-891-4968 before you sign a proposal. If another provider serves your home, these City programs do not apply, and we can go over other options, including Breeze lease-to-own financing.

Why Tallahassee Homeowners Choose Sterling Service

Founder Roger Hays brings more than 40 years of HVAC experience to a veteran-owned, family-operated company that holds a Florida Class A air conditioning contractor license. Reviews from Tallahassee customers keep returning to the same point: technicians explain the problem and name the cheaper fix when one exists. One customer wrote that Roger helped them avoid new ductwork another company had proposed. If you are weighing a big job, we are glad to give you a second opinion before you commit.

Answers to Common Heating and Cooling Questions

Can I get a City of Tallahassee rebate if my electric service isn’t through the City?

For an existing home, no. The City’s HVAC rebates are available only to City of Tallahassee residential electric customers, and the equipment must be installed under a permit and pass final inspection. If your electric bill comes from another provider, ask that provider about its own programs, and ask us about financing options that do not depend on your utility.

Should I repair or replace my AC in my Tallahassee home?

A common rule of thumb multiplies the repair quote by the unit’s age in years; if the result is above $5,000, replacement usually makes more sense. Central systems typically last 15 to 20 years, so an older unit with a costly repair is a replacement candidate, while a younger unit with one failed part usually is not. We give you the repair price and the replacement price side by side so the comparison is yours to make.

Why is my AC running but not cooling my Tallahassee house?

Start with the basics: a clogged filter, a blocked outdoor unit, or a thermostat set wrong. If those check out, the likely culprits are a frozen coil, a weak capacitor or fan motor, or a refrigerant leak. Ice on the indoor unit means shut the system off and let it thaw before it runs again. Low refrigerant always points to a leak, which a licensed technician has to locate and fix.

Why does my Tallahassee home feel humid even when the AC is running?

A system that cools quickly and shuts off can leave moisture behind, and leaky ducts, poor airflow, or a fan setting left on continuously can add to it. A technician checks run times, airflow, and the duct system to see which applies, and in some homes added humidity control is part of the answer.

Should a Tallahassee home use a heat pump or an AC with a gas furnace?

A heat pump handles both cooling and heating from one system, while an AC paired with a gas furnace relies on gas service for heat. The right choice depends on whether the home has gas, how the ducts are laid out, and the cost of each fuel. Rebate and loan programs also differ for gas equipment, so we compare the options for your address before you decide.

When is the best time of year to replace an HVAC system in Tallahassee?

Plan it before the cooling season peaks. A replacement scheduled in spring or fall gives you time to compare quotes, line up a loan approval before work begins, and pass the final inspection within the City’s rebate window, all without a no-cooling emergency forcing the timeline.
