What Hernando County Homeowners Ask About Heating and Cooling

After years of working on homes in Spring Hill, Brooksville, Weeki Wachee and Hernando Beach, a handful of questions come up again and again. Here are the ones we hear most, with answers that reflect how air conditioning behaves in a hot, humid, salt-touched part of Florida.

How long should an air conditioner last here?

Ten to fifteen years is the common range, and Florida's long cooling season tends to put systems at the shorter end. Regular maintenance, a clean coil and correct sizing add years. Homes near the coast, where salt air corrodes outdoor coils and fittings, may need to watch the outdoor unit more closely.

Why does my house feel sticky even when the air conditioner is running?

Humidity, not temperature, is usually the cause. A system that is too large reaches the thermostat setting quickly and shuts off before it has removed much moisture. A system that is dirty or low on refrigerant dehumidifies poorly as well. Look at sizing, coil cleanliness and airflow before you simply lower the thermostat.

Is a bigger system better?

No. An oversized unit cycles on and off frequently, wastes energy, wears out sooner and leaves the air damp. The right size comes from a load calculation of your house, not from the size of the old unit.

How often should I change the filter?

Every one to three months in most homes, and monthly in summer or if you have pets or allergies. A clogged filter restricts airflow, makes the system work harder and is behind many service calls.

Do I really need maintenance if it is working?

Yes, for the same reason a car needs oil changes before it stops. A tune-up cleans the coils, checks refrigerant and electrical connections, and tests the capacitor, so a small, inexpensive problem is caught before it causes a breakdown on a hot day.

What does salt air do to an air conditioner?

Salt accelerates corrosion on coils, fasteners and electrical connections, particularly on homes near the Gulf. Rinsing the outdoor unit with plain water on a regular basis, as your technician advises, and keeping it clear of vegetation helps, and a coil with a protective coating can last longer.

When should I replace instead of repair?

Consider replacement when the system is past about twelve years old and a major part has failed, when repairs keep recurring, or when the cost of a repair approaches a large portion of a new system's price. A good technician will put the choices side by side in writing.

What should I do before a hurricane?

Switch the system off at the breaker before the storm arrives so a surge or power flicker cannot damage the compressor, and make sure the outdoor unit is clear of loose items. After the storm, have the unit inspected before running it, particularly if there was flooding.

What efficiency rating should I look for?

Higher SEER2 ratings use less electricity, and in a state where the air conditioner runs most of the year the savings accumulate. The right balance depends on your budget and how long you plan to stay in the house.
