HVAC questions, answered for Port Richey, FL.

In west Pasco, a central air conditioner or heat pump commonly lasts around 10 to 15 years. Florida systems run far more hours than systems up north, and coastal salt air shortens the life of outdoor units.

Regular maintenance, clean coils and a clear drain line help a system reach the longer end of that range.

Replacement usually makes sense when the system is past about 12 to 15 years old and needs a major repair such as a compressor or a coil, when it runs on R-22 and has a significant leak, or when it breaks down repeatedly.

Small, inexpensive repairs like a capacitor, contactor or drain clearing are usually worth doing even on an older system. Ask for both prices and decide with real numbers.

Common causes are a failed capacitor or contactor at the outdoor unit, a tripped breaker, a frozen indoor coil, a low refrigerant charge from a leak, or a safety switch shut off by a clogged drain.

Check that the thermostat is set to cool and that the filter isn’t clogged. If the outdoor fan isn’t spinning or the indoor coil is iced over, turn the system off and call. Running it can damage the compressor.

Ice on the indoor coil or the copper lines usually means too little airflow or too little refrigerant. A dirty filter, closed vents, a dirty coil or a failing blower are the airflow causes; a leak is the refrigerant cause.

Turn the system to off (leave the fan on to help it thaw), replace the filter if it’s dirty, and call if it freezes again. Don’t chip at the ice.

The right size comes from a load calculation (Manual J) that accounts for square footage, windows, insulation, orientation, ductwork and the people living there, not from square footage alone.

Oversizing is a common Florida mistake. A system that’s too big cools fast, shuts off and leaves the house cool but clammy.

Yes. Their website says they have flexible financing options to make an upgrade more affordable.

Ask for the details when you get a replacement quote.

Indoors, aim for roughly 40 to 60 percent relative humidity, and lower in that range is better for preventing mold and dust mites. EPA guidance suggests keeping it under 60 percent.

If your house feels cool but sticky, or you see condensation on vents or windows, your system may not be removing enough moisture.

Usually the system cools the air but doesn’t run long enough to remove moisture. Oversized equipment, a fan left in the On position, high airflow settings and duct leaks that pull in humid attic air are the common causes.

Try setting the fan to Auto first. If it’s still clammy, have a tech check sizing, airflow and duct leakage.

The most common cause in Florida is a condensate drain line clogged with algae and sludge, which overflows the drain pan. A rusted pan or a frozen coil thawing are the next most likely causes.

Turn the system off at the thermostat, keep clear of any water near electrical parts, and call for service.

Have the drain flushed and the float switch tested at every maintenance visit. Between visits, many homeowners pour about a cup of plain white vinegar into the drain’s access port every month or two to slow algae growth.

Turn the system off first, use only the access port (not the air handler cabinet), and never mix vinegar with bleach or other cleaners. If water is backing up, call.

A float switch is a small safety device that shuts the air conditioner off when water rises in the drain pan or line, before it overflows into the ceiling or floor.

In Florida, where drains clog often, a working float switch is cheap insurance. If your system shuts off on a hot day and the pan is full, the switch probably did its job.

Yes. Better filtration, air purification and ventilation, together with good humidity control, can reduce dust, pollen and musty odors. Cowpoke Cooling offers indoor air quality solutions that include filtration, purification and ventilation.

A persistent musty smell can also mean moisture in the ducts, a dirty coil or a clogged drain, so have the system checked before adding equipment.

For many homes, a correctly sized and maintained air conditioner controls humidity well on its own. A dedicated dehumidifier helps in homes that stay humid anyway: tight new construction, homes with low cooling loads in spring and fall, or houses near the water.

Measure first. A simple hygrometer reading over a few weeks tells you whether you have a problem worth solving.

Clear and secure loose items around the outdoor unit. If you’re evacuating or expect flooding, turn the system off at the thermostat and at the outdoor disconnect or breaker.

Don’t wrap the unit in plastic or tarp it tightly while it can still run, and follow official evacuation orders before worrying about equipment.

Only if the equipment wasn’t flooded or damaged. Walk around the outdoor unit first. If it was underwater, is tipped or dented, has debris inside or the wiring looks damaged, leave the power off and call for an inspection.

If it looks fine, wait until power is stable, then turn the breaker and disconnect back on and start the system at the thermostat.

Not always, but it must be inspected before it runs again. Salt water is especially hard on electrical parts, controls and coils, and floodwater can contaminate ductwork and the air handler.

Never restart flooded equipment yourself. Take photos for your insurance claim and have a licensed contractor evaluate it.

It’s worth considering. Lightning and the power surges that come when the grid comes back after a storm can damage the control boards and compressors in modern equipment.

Surge protection for HVAC equipment should be installed by a qualified professional; ask about it during maintenance or replacement.

Some window units and small mini-splits can run on a large portable generator, but a central air conditioner usually needs more power than a portable generator can deliver, and it must be connected through a proper transfer switch or interlock installed by a licensed electrician.

Never back-feed a generator into the house through an outlet, and never run a generator indoors, in a garage or near windows. Carbon monoxide kills.

The Atlantic hurricane season runs from June 1 to November 30, with the peak usually from mid-August through October.

Spring, before the heat and the storms arrive, is the best time for a maintenance visit or a planned replacement.

At least twice a year, before summer and before winter. That’s what Cowpoke Cooling recommends.

In Florida, where cooling runs most of the year, the spring visit matters most: clean coils, a flushed drain and checked electrical parts going into the hottest months.

Check it monthly. Basic 1-inch filters usually need changing every 1 to 3 months here, and more often with pets, construction dust or heavy use. Thicker media filters can last longer; follow the maker’s guidance.

A clogged filter cuts airflow, freezes coils and raises your bill. Make sure the airflow arrow points toward the air handler.

A good tune-up includes cleaning or checking the indoor and outdoor coils, flushing the condensate drain and testing the float switch, checking capacitors, contactors and wiring, checking refrigerant performance, and verifying airflow and thermostat operation.

For commercial customers it also covers belts, motors and economizers on rooftop units.

You can keep the area around it clear: trim plants back at least 2 feet and remove leaves and debris. With the power off at the disconnect, a gentle rinse with a garden hose from the inside out is fine.

Don’t use a pressure washer, don’t bend the fins, and leave anything inside the cabinet, including electrical parts and refrigerant lines, to a technician.

Signs include rooms that never get cool, high bills, dusty rooms, and a hot, humid attic smell at the vents. In most west Pasco homes the ducts run through the attic, so a leak pulls in some of the hottest, wettest air in the house.

A tech can inspect accessible ductwork and measure airflow. Cowpoke Cooling installs, repairs and replaces duct and vent systems.

Not on a fixed schedule. Duct cleaning makes sense when there’s visible mold growth, after construction or renovation dust, after pests, or when the ducts are clogged with debris.

Fix moisture and filter problems first; otherwise clean ducts get dirty again.

Yes, for most homes. West Pasco’s winters are mild, so a heat pump heats efficiently nearly all season and cools like a standard air conditioner the rest of the year. Most systems include electric backup heat for the occasional cold snap.

In a cold snap the backup heat may come on more often, which is normal; a burning smell the first time it runs each winter is usually dust burning off.

SEER2 is the cooling efficiency rating used on new equipment since 2023; higher numbers use less electricity. Florida is in the Department of Energy’s Southeast region, where new split central air conditioners must be at least 14.3 SEER2 (under 45,000 Btu/h) or 13.8 SEER2 (larger systems).

Heat pumps must meet 14.3 SEER2 and 7.5 HSPF2 nationwide. In a climate with this many cooling hours, going higher can pay off, but sizing and installation matter as much as the rating.

R-22 (often called Freon) was phased out: US production and import ended on January 1, 2020. Existing systems can still be serviced with recovered or stockpiled R-22, but it is scarce and expensive.

If an R-22 system develops a significant leak, replacement is usually the better value.

They are the lower global-warming-potential refrigerants replacing R-410A in new residential air conditioners and heat pumps under EPA rules that took effect in 2025. A2L means they are mildly flammable, so equipment and installation follow updated safety standards.

Your existing R-410A system can still be repaired and serviced. Refrigerant work of any kind requires an EPA-certified technician; it’s not a DIY job.

Often, yes, for additions, converted garages, sunrooms, workshops and rooms the central system can’t keep comfortable. They are efficient, need no ductwork and can be zoned room by room.

Their drain lines and filters need regular attention, just like a central system.

It can be, if it’s compatible with your system and set up correctly. Scheduling, remote control and humidity readings are useful in Florida.

A poorly matched thermostat can cause short cycling or confuse a heat pump’s backup heat, so have it checked against your equipment. Cowpoke Cooling’s AC repair work includes thermostat problems.

Yes. Cowpoke Cooling’s refrigeration services include restaurant freezer repairs and walk-in cooler maintenance.

If a walk-in is warming up, keep the door closed, move critical product to working storage if you can, and call (727) 225-4368.

Common causes are a door that doesn’t seal or is left open, a failed defrost heater, timer or control, a blocked evaporator drain, or a fan problem. Humid Florida air makes a bad door seal worse fast.

Check the door gasket and that the door closes fully, then call for service before the ice blocks airflow completely.

Look the license up on the Florida Department of Business and Professional Regulation (DBPR) website, myfloridalicense.com. Air conditioning contractors are licensed through the Construction Industry Licensing Board.

Cowpoke Cooling’s license number, CAC182269, is shown on their website. A license number that starts with CAC is a state-certified air conditioning contractor license.

Generally, yes. Replacing a central air conditioner or heat pump in Florida requires a mechanical permit, issued by Pasco County in unincorporated areas or by your city if you live inside city limits.

The contractor normally pulls the permit and arranges the inspection. Ask whether it’s included in your quote.

Ask for the license number and verify it, ask whether they carry insurance, get a written quote that names the equipment and its efficiency rating, and ask whether the permit is included.

Be cautious with anyone who quotes a replacement over the phone without seeing the house, or who won’t put the price in writing.

Leave the house right away. Don’t flip light switches, use the phone inside, or start a car in the garage. From outside, call your gas utility or 911.

Don’t go back in until the utility or fire department says it’s safe.

Get everyone, including pets, out into fresh air immediately and call 911 from outside.

Don’t go back in until responders say it’s safe. Then have every fuel-burning appliance inspected before it’s used again.

Check the thermostat setting and batteries and the breaker for the air handler, then call for service. Dress in layers and use safe, approved electric space heaters kept well away from anything that can burn.

Never use an oven, stove, grill or generator indoors for heat. They can start fires or produce deadly carbon monoxide.
