Is Lightning Fast A/C & Heating licensed and insured?

Yes, we are a licensed and insured Florida air conditioning contractor. We're also locally owned and family operated, so the people answering the phone and the people in your driveway are the same team.

Does Lightning Fast A/C & Heating offer financing?

Yes. We offer flexible financing options with fast approval on repairs and new system installations, so a failed AC doesn't have to mean draining your savings. Ask about financing when you call (813) 743-2353.

Do you charge extra for nights, weekends or holidays?

We keep after-hours pricing fair and always tell you the price before work begins. One of our Google reviewers called us out on a holiday weekend, 4th of July, and still described our pricing as great.

Will you try to sell me a new AC system when mine can be repaired?

No, the opposite is our reputation. Our Google reviews repeatedly say we're 'extremely honest and did not try to upsell.' If a repair makes sense, we repair. If replacement genuinely makes sense, we'll show you the math and offer financing.

What brands of AC equipment do you service?

All major brands: Trane, Carrier, Goodman, Rheem, Ruud, Lennox, York, Daikin, Amana, TopTech, Bryant and more. Our trucks stock the common failure parts, capacitors, contactors, motors, so most repairs finish in one visit.

How often should I have my AC serviced in Florida?

At least once a year, Florida systems run 9+ months a year in extreme humidity, the hardest duty cycle in the country. A spring tune-up prevents the most common summer breakdowns and keeps energy bills down.

Why is my AC running but not cooling the house?

The most common causes in Florida are a dirty condenser coil, low refrigerant from a leak, a failing capacitor, or a frozen evaporator coil. Turn the system off so any ice can thaw, then call us, diagnosis is fast and we quote the fix before touching anything.

How long does an AC system last in Florida?

Typically 10-15 years here, versus 15-20 up north, heat, humidity and near-year-round runtime take their toll, and salt air shortens that further near the bay. Annual maintenance is the single biggest factor in reaching the long end of that range.

Is Lightning Fast A/C & Heating family owned?

Yes, we're a locally owned, family-operated company based in Lithia, FL. When you call, you're talking to the people whose name is on the van, not a national call center.

Do you install smart thermostats?

Yes, Nest, ecobee, Honeywell and more, wired correctly for heat pumps and auxiliary heat (the part DIY installs most often get wrong), and configured with Florida-appropriate schedules and humidity settings.

What should I set my thermostat to in Florida summer?

78°F when home is the efficiency sweet spot; each degree cooler adds roughly 6-8% to cooling costs. If 78 feels sticky, the real problem is usually humidity, something a properly sized, well-maintained system fixes.

Do you handle both heating and air conditioning?

Yes, it's in our name. We repair, maintain and install air conditioning, heat pumps, electric heat and furnaces. Stay cool in July, stay warm on those few frosty January mornings, one local company for both.

Do you do commercial HVAC work?

Yes, restaurants, offices, retail, gyms, churches and warehouses across Hillsborough County. Packaged rooftop units (RTUs), split systems, commercial ductwork and preventive maintenance agreements with priority dispatch, scheduled around your business hours.

How much does AC repair cost?

It depends entirely on the problem, from around $150 for a capacitor to a few hundred for a coil cleaning or drain clearing, and more for a refrigerant leak repair. We diagnose the real cause first and give you an exact price in writing before any work starts, so there are no surprises.

How much does a new AC system cost in Hillsborough County?

Roughly $6,000 to $9,000 for a standard-efficiency system and $9,000 to $14,000 or more for high-efficiency or larger systems, including the permit and installation. Exact pricing depends on tonnage, efficiency and your ductwork, and financing is available either way.

Should I repair or replace my air conditioner?

A useful rule is to multiply the repair cost by the system's age in years; over about $5,000, start pricing replacement. Age, R-22 refrigerant, rising bills and repeat repairs all push toward replacement. We show you the honest math both ways and never pressure a sale.

Why is my AC leaking water inside?

Almost always a clogged condensate drain line. Your AC pulls gallons of water from humid Florida air daily, and when algae clogs the drain, water backs up and leaks or trips the safety float switch. Turn the system off and call us; it's a common, usually inexpensive fix.

Why is my electric bill so high in the summer?

In Florida, air conditioning is usually half or more of the summer bill because it runs most of the day for nine months. An aging, dirty, low-charge or leaky-duct system quietly pushes that cost higher, and a tune-up often restores lost efficiency quickly.

Do you offer free estimates on new systems?

Yes. We provide free, no-pressure estimates on new system installations and replacements, with the price in writing and honest sizing based on a real load calculation for your home, not a guess off square footage. Call (813) 743-2353 to schedule one.

What is the best AC temperature to save money in Florida?

About 78°F when you're home and a few degrees higher when you're away, with the fan set to AUTO so it isn't re-humidifying the house. Each degree cooler adds roughly 6 to 8 percent to cooling costs, and a smart thermostat automates the savings.

Can you help if my AC quit on a holiday or weekend?

Yes. We answer seven days a week, including nights and holidays, because Florida heat doesn't take a day off. One of our five-star reviews came from a family we rescued over the Fourth of July weekend, same-day, at a fair price.

How do I prevent my AC drain line from clogging?

Pour a cup of distilled white vinegar into the condensate drain access tee near your air handler every one to two months during cooling season. It breaks down the algae that causes most Florida drain clogs, the number one cause of AC water damage and shutoffs.

Why does my house feel humid even when the AC is running?

Usually the fan is set to ON instead of AUTO, which re-evaporates moisture back into the air, or the system is oversized and shuts off before dehumidifying. A dirty coil or low refrigerant charge also hurts moisture removal. Aim for 45 to 55 percent indoor humidity.

Do you install mini-split systems for garages and additions?

Yes. Ductless mini-splits are perfect for garages, enclosed lanais, workshops, additions and that one room the central system can't keep comfortable. They need no ductwork, install cleanly, heat and cool, and are very efficient. We size and install single-zone and multi-zone systems.
