Keep Your Home Comfortable All Year Whether You’re in Sun City or Not

Air Shield understands that there are many snowbirds in addition to our all year citizens here in Sun City Center. We understand the varying needs of someone who is in their home all the time and the person who leaves their home vacant for half the year.

We offer HVAC maintenance programs that help protect your home from mildew and mold and keep the system running strong even when you’re out of state. Since it’s hot for most of the year here in Sun City, having a running AC with a dehumidistat system is important to keep humidity in check while you’re away.

What a Dehumidistat Does for Sun City Center Homes

A dehumidistat is a device that controls the humidity levels in your home by communicating with the thermostat to change the temperature. It is perfect for Florida snowbirds that leave their Florida home for long periods.

Heat Pump Repair in Sun City Center

Many Sun City Center villas and homes heat and cool with a heat pump paired with an air handler in a hall closet. The outdoor unit does most of the work. Electric heat strips in the air handler step in on the coldest mornings.

Our technicians repair heat pumps across Sun City Center, from the original village to Kings Point. Calls we handle include:

• Short cycling: A heat pump that starts and stops every few minutes may have a failing contactor or a low refrigerant charge.
• Cool air on a heating call: A stuck reversing valve keeps the system in cooling mode.
• Water around the air handler: A clogged condensate line can overflow the drain pan inside the closet. These tips on preventing AC drain line clogs apply to heat pumps too.
• Musty smell after time away: Moisture builds in the coil and drain pan while a home sits closed.
• Noisy outdoor fan: Worn motor bearings or a cracked fan blade are the usual causes.

Our guide on when to call for AC repair in Sun City Center covers the cooling-side warning signs in more detail.

Our technicians also service heat pumps in nearby Ruskin and Apollo Beach. Homes east of US 301 in Wimauma get the same coverage.

Heat Pump Startup Checks for Seasonal Sun City Center Homes

A heat pump that ran on a dehumidistat schedule for six months needs a quick check before it carries a full load again. We recommend a startup visit within a few weeks of your return.

• Replace the air filter, which collects dust even while the house is closed
• Flush the condensate drain line and check the drain pan
• Clean the outdoor coil and clear leaves and grass clippings from around the unit
• Test the heat pump in both heating and cooling modes
• Reset the dehumidistat and thermostat for full-time living

Frequently Asked Questions About Air Conditioning in Sun City Center

What temperature should I keep my thermostat set at?

To save the most on energy costs and wear and tear on your machine, 78 degrees or higher is recommended. Some people are not comfortable at this temperature but do your best to keep it there for as much time as possible during the day.

For most people, the temperature is more important at night, so, keep your system at 78 during the heat of the day and turn down the AC in the evening so it won’t have to work so hard to maintain it.

Every degree below 78 will cost you more in energy cost though, so that’s something to consider.

When I go out of town, or away for the summer, what should I set the thermostat at?

Some people might be tempted to turn the system off, but this would be a big mistake. You definitely want to keep the system running.

It should be set on 82 for the majority of the day but have the system either on a dehumidistat or timer to have it run at 72 degrees for at least two hours a day.

This will help keep the humidity levels of your home at the correct levels and cut down on mold and mildew production. It will also keep your AC operating costs low.

What’s the difference between a timer and a dehumidistat?

A timer runs at a specific time of the day. The dehumidistat will turn on anytime the relative humidity goes above the setting you’ve programmed. A relative humidity setting of 65% is a good level to keep it at.

If I close my vents in rooms I’m not using, will that save money?

It’s not recommended to close the vents. The cost savings are negligible and the air balance throughout the home will be imbalanced which will raise the relative humidity and can cause mold problems.

Keep all the vents open and clean for your system to run at its highest efficiency.

Should I leave my heat pump on heat or cool while I’m away for the summer?

Leave it on cool. A Sun City Center summer brings heat and humidity every day. A heat pump left on heat or switched off cannot pull moisture from the house. Pair the cool setting with a dehumidistat so the system runs whenever indoor humidity climbs.

What should I check on my heat pump when I return in the fall?

Start with a fresh air filter and a look at the drain pan under the air handler. Then switch the system to cool and to heat, and confirm air changes temperature in each mode. Book a startup visit if you notice a musty smell, standing water, or weak airflow.

Why does my heat pump make a whooshing sound and release steam in winter?

That is the defrost cycle, and it is normal. On cool, damp mornings, frost forms on the outdoor coil. The heat pump briefly reverses to melt it, which makes a whoosh and a cloud of steam. Call for service if the coil stays coated in ice for more than an hour.

Heat Pump Repair Results From Sun City Center, FL Homes

Musty Air After a Summer Away

A Kings Point snowbird returned in October to musty air and a heat pump holding the house at 80 degrees. Our technician found a clogged drain line and a dirty indoor coil. We cleared both. The system cooled normally.

Heat Strips Carrying the Whole Load

An original-village homeowner opened a December electric bill far higher than usual. Our technician found the outdoor unit idle on a failed contactor, leaving the heat strips to run alone. We replaced the contactor and restored normal heat pump heating.

Control Board Lost After a Summer Storm

A Renaissance homeowner came home to a silent heat pump after a July thunderstorm. Our technician traced it to a control board damaged by a power surge. We replaced the board, tested both modes, and suggested a whole-home surge protector.
