AC Installation & Replacement

St. Petersburg’s heat and salt air are brutal on HVAC equipment. Most systems in our area last 10–15 years before they need replacement — shorter than the national average due to near year-round operation. When it’s time for a new system, Hales AC performs a detailed Manual J load calculation to size your unit correctly for your home. An oversized system short-cycles and fails to dehumidify. An undersized system runs constantly and can’t keep up in July. We get it right.

We install high-efficiency systems from Carrier, Lennox, Trane, Rheem, and other leading manufacturers, and we offer financing options to make a new system affordable.

Preventive Maintenance

Florida’s climate pushes AC systems harder than almost anywhere in the country. Skipping maintenance in St. Petersburg is a recipe for breakdowns at the worst possible time. Regular tune-ups catch small problems before they become expensive emergencies, improve energy efficiency, and extend your system’s lifespan.

Indoor Air Quality

St. Petersburg’s humidity creates ideal conditions for mold, mildew, and allergens inside your ductwork. Hales AC offers air purification systems, UV germicidal lights, dehumidifiers, and duct cleaning to improve the air your family breathes every day.

Duct Repair & Sealing

Leaky ductwork wastes up to 30% of your conditioned air — and in a St. Petersburg attic that reaches 150°F in summer, that lost air costs you real money. We test, seal, and repair ductwork to make sure every dollar you spend on cooling actually reaches your living spaces.

Frequently Asked Questions About HVAC Service in St. Petersburg

How often should I service my AC in St. Petersburg’s climate?

In St. Petersburg, we recommend servicing your air conditioning system at least twice per year — once in early spring before cooling season begins and once in fall. Because AC systems in Florida run nearly year-round, they accumulate wear faster than systems in northern climates. Twice-yearly maintenance catches refrigerant leaks, electrical issues, and drainage problems before they lead to costly breakdowns. Hales AC’s Comfort Club includes both tune-ups at a discounted annual rate.

How long do AC systems last in Florida?

The average air conditioning system in St. Petersburg lasts 10–15 years with proper maintenance. That’s shorter than the 15–20 year national average because Florida systems run 2,500–3,000+ hours per year compared to 1,000–1,500 hours in moderate climates. Coastal St. Petersburg homes face additional stress from salt air corrosion on outdoor condensing units. Regular maintenance, keeping the area around your outdoor unit clear, and rinsing salt residue from condenser coils can help maximize your system’s lifespan.

What size AC system do I need for my St. Petersburg home?

Proper sizing requires a Manual J load calculation that accounts for your home’s square footage, insulation, window count and orientation, ductwork condition, ceiling height, and roof type. As a rough guideline, most St. Petersburg homes need 1 ton of cooling per 500–600 square feet, but this varies significantly. A 2,000-square-foot home might need a 3.5 to 4-ton system. Hales AC performs load calculations on every installation to ensure correct sizing — an oversized unit short-cycles, wastes energy, and fails to control Florida’s humidity.

Why is my AC running but not cooling my house?

Several common issues cause an AC to run without cooling effectively in St. Petersburg. Low refrigerant from a leak is the most frequent cause — your system can’t cool without adequate refrigerant charge. A dirty or frozen evaporator coil restricts airflow and reduces cooling capacity. A failing compressor may run without actually compressing refrigerant. A clogged air filter — especially common during high-pollen seasons in the Tampa Bay area — reduces airflow across the evaporator coil. If your AC is running but your home isn’t cooling, call Hales AC at (727) 398-5515 for a diagnostic before the problem worsens.

Is it worth repairing my old AC or should I replace it?

We use a straightforward guideline: if your system is over 10 years old and the repair costs more than 50% of a new system, replacement is usually the better investment. Newer systems are significantly more efficient — upgrading from a 10 SEER unit (common in older St. Petersburg homes) to a 16+ SEER system can reduce your cooling costs by 30–40%. With FPL rates continuing to rise, that efficiency gain pays for itself. Additionally, newer systems use R-410A refrigerant instead of the phased-out R-22, which has become extremely expensive to recharge. Hales AC will always give you an honest assessment — we never push replacement when a repair makes more sense.
