AC Maintenance in Oldsmar, FL: Tune-Ups Timed for Humidity and Storms

Oldsmar sits on the north shore of Tampa Bay, at the far eastern edge of Pinellas County.

ENERGY STAR recommends an annual pre-season check-up by a contractor. It suggests checking the cooling system in the spring, because contractors get busy once summer comes. An easy reminder is the spring time change.

For what belongs to you and what belongs to a technician through the year, see our AC maintenance checklist for Florida homes.

The National Weather Service defines the dew point as the temperature at which water vapor turns into liquid droplets. The higher the dew point, the more moisture is in the air and the muggier it feels.

What the Tampa records show

The Weather Service's Tampa office analyzed hourly dew point readings at Tampa going back to 1948. The highest it found was 86°F, on August 6, 2000. Its longest run of days with dew points at 75°F or higher was seven, from August 5 to 11, 2024.

ENERGY STAR lists checking the condensate drain as part of a typical maintenance check-up. It says a plugged drain can cause water damage in the house and affect indoor humidity levels.

If your house feels clammy even when the thermostat reads normal, our guide to a house that stays humid with the AC running explains the usual causes. For a drain that backs up, see AC drain line clogged.

ENERGY STAR lists what a typical maintenance check-up should include. On a central air conditioner, that means:

• Thermostat settings, so the system keeps you comfortable at home and saves energy while you are out.
• Electrical connections, tightened, with voltage and current measured on the motors. ENERGY STAR says faulty connections can cause unsafe operation and shorten the life of major parts.
• Moving parts, lubricated.
• The condensate drain, checked and inspected while the system is in cooling mode.
• The starting cycle, to confirm the system starts, runs and shuts off properly.
• Both coils, the indoor evaporator and the outdoor condenser, cleaned. Dirty coils reduce cooling and make the system run longer.
• Refrigerant level, checked and adjusted if needed.
• Blower components, cleaned and adjusted for proper airflow.

Blume sizes equipment by ACCA Manual J load calculation rather than rule of thumb. New equipment is commissioned with measured static pressure, airflow and refrigerant charge, and the results are documented. Refrigerant work is done by EPA Section 608 certified technicians.

If your outdoor unit is close to the bay, ask about coil care as part of the visit. Our guide to coastal coil protection covers it.

The City of Oldsmar publishes a storm checklist for residents. Several items touch the air conditioner directly, even though the list is about the whole property.

• Loose items. The city asks residents to take all yard items inside and to pick up or secure loose debris.
• Trees and palms. The city says pruning can reduce wind damage. For palms, it says to remove brown, broken and dead fronds and leave the green ones.
• Drainage. Before a storm, the city asks residents to clear gutters and storm drains of leaves and items that could block drainage.
• Power. If you leave, the city says to shut off power before you go.

Know where your property sits

The city points residents to Forerunner, a platform with flood-risk information by address. A search shows the property's flood zone and its Base Flood Elevation, among other details. If an Elevation Certificate is on file for the property, you can find it through the searchable Elevation Certificate page.

The city says that once you have determined your house lies in a flood zone, an Elevation Certificate can tell you how high your house was built in relation to that flood zone. That is useful context when you and your technician talk about a ground-level condenser.

Oldsmar also has three evacuation zones: Mobile Homes, Zone A and Zone B. The city reminds residents that an evacuation zone is not the same as a FEMA flood zone. Pinellas County says residents of mobile homes, manufactured homes and recreational vehicles must always evacuate, no matter what area of the county they live in. It says residents who are dependent on electricity must always evacuate due to winds for all category hurricanes.

Storm surge, the city says, impacts coastal areas first, such as Oldsmar. If water or wind damage reached your home, the city's advice comes before any maintenance visit.

• Look first. Before going in, the city says to look outside for damaged power lines, gas lines and other exterior damage.
• Power off until it is safe. The city says to keep the main electrical power off until you or a professional can confirm it is safe. Never switch power on or off while standing in water.
• Air the house out. If the house was closed for more than 48 hours, the city says to let the air out before staying inside for long.
• Generators. The city says not to connect a portable generator to a home's electrical system. If you are thinking of buying one, it says to get advice from a professional, such as an electrician.

Permits after a storm

The city's post-storm guide says permits are required for electrical reconnections and meter resets, and for flood damage restoration. It also says permitting rules after a flood differ from routine permitting. All work in flood zones needs a permit before it begins.

For storm recovery permitting, the city asks residents to email building@OldsmarFL.gov or call Planning & Redevelopment at (813) 749-1142. If your system will not run after a storm, see our page on AC repair in Oldsmar.

Pinellas County's economic development office lists Tampa Electric as the utility serving Oldsmar. If your bill comes from Tampa Electric, two of its programs sit close to a maintenance visit.

The first is its Energy Audit. Tampa Electric offers a free Energy Audit, and you can schedule a free in-home audit with one of its energy experts.

The second is its Ductwork program. Tampa Electric says a pre-approval inspection by one of its energy analysts is required. The analyst inspects your duct system for accessibility and repair needs.

A few checks need no tools and no open panels.

• Filter. ENERGY STAR says to inspect, clean or change the filter once a month. It warns that a dirty filter can damage equipment and lead to early failure. Your contractor can show you how.
• Thermostat. Confirm the mode and set temperature before assuming the system has a fault.
• Outdoor unit. With the system off, clear leaves, fronds and storm debris away from the cabinet by hand.
• Drain line. Look at where the condensate line ends outside, and call a contractor if water is pooling around the indoor unit instead.

Leave refrigerant, wiring, capacitors and anything behind a panel to a licensed contractor.
