What our Lake Mary customers are saying

Lake Mary homeowners trust us for precise, thorough HVAC service. Read what they have to say, or explore our full AC service.

“Moved into a newer home near International Parkway and the thermostat wasn’t set up properly. The system was short-cycling and our electric bill was way too high. Premier Frost recalibrated the system, set up the Ecobee properly, and explained exactly what was wrong. Bill dropped significantly the next month.”

Jennifer K.
International Parkway
Job completed
A Lake Mary homeowner near International Parkway reported high energy bills and a system that cycled on and off frequently after a recent move-in. We identified incorrect thermostat configuration causing short-cycling, recalibrated the system, and set the smart thermostat to an efficient schedule. Energy use dropped noticeably within the first billing cycle.

“Had Premier Frost come out for an annual AC checkup before summer. They found a capacitor starting to fail and replaced it on the spot. Prevented what would have been a breakdown call in August. Worth every penny of the maintenance fee.”

Lake Mary Boulevard
Job completed
A Lake Mary homeowner booked a pre-summer AC maintenance visit on Lake Mary Boulevard. Our technician identified a weakening run capacitor during testing and replaced it on the spot. The homeowner avoided a summer breakdown and the system ran without issue through the season.

“Upgraded from a traditional tank to a tankless water heater. The team was thorough, explained the installation requirements clearly, and finished in half a day. The Heathrow HOA had specific requirements about exterior work and they handled everything without any issues.”

Complete AC services for Lake Mary homes

Newer Lake Mary homes often have higher-efficiency systems, but efficiency drops when maintenance is skipped and calibration drifts. An annual seasonal AC checkup keeps the system running at its rated efficiency and catches developing faults before they cause a breakdown in peak summer heat.

AC repair in Lake Mary

Same-day diagnosis and repair for all AC faults. For Lake Mary homes where the system is 12 or more years old, we’ll assess whether repair or full AC replacement is the better investment. View our AC repair service.

AC maintenance

Annual AC maintenance keeps newer systems running at rated efficiency. We clean coils, check refrigerant, calibrate controls, and test the full system. Starts from $99.

Mini split AC

Mini splits are a clean solution for Lake Mary home offices, bonus rooms, and three-season Florida rooms where extending existing ductwork isn’t practical. Most installations are completed in a single day.

AC installation

When it’s time to replace, we size the new system correctly for your home’s layout and insulation level. Oversizing is a common mistake in Lake Mary installs that leads to short-cycling and humidity issues. Free estimates on every replacement job. View our AC installation service.

Furnace, heat pump, and thermostat services in Lake Mary

Many Lake Mary homeowners have moved to heat pump systems as their primary heating and cooling solution, taking advantage of Florida’s mild winters to run a single efficient unit year-round. Smart thermostat integration maximises this efficiency further.

Furnace installation and repair in Lake Mary

Installation and repair for all furnace makes and models. If you’re weighing a furnace against a heat pump, we’ll give you an honest comparison based on your home’s existing setup and your usage patterns. View our furnace service.

Heat pump installation and service

Heat pumps suit Lake Mary’s climate well: efficient cooling in summer and reliable heating in winter without the operating cost of resistance heating. Pairing with a smart thermostat improves efficiency further. View our heat pump service.

Smart thermostat installation

Lake Mary’s tech-forward households frequently upgrade to Nest or Ecobee smart thermostats for remote control and energy scheduling. We install, configure, and integrate with all major smart home platforms. View our thermostat installation service.

Water heater installation and repair

Lake Mary’s newer homes often have tankless water heaters already installed, but many properties in the Heathrow and older Lake Mary neighbourhoods are still running traditional tank units well past their recommended service life. We handle both tank replacement and tankless water heater installation across the Lake Mary area.

Tank water heater services in Lake Mary

Repair, inspection, and same-day replacement for traditional tank water heaters. We work with all major brands and provide free estimates on every replacement job. View our tank water heater service.

Tankless water heater installation

Tankless units deliver hot water on demand, use less energy than tank models, and suit the larger, higher-occupancy homes common in Lake Mary’s residential communities. View our tankless water heater installation service.

Air duct cleaning and indoor air quality

Even newer ductwork in Lake Mary homes accumulates construction dust, pollen, and debris over time. For households with allergies or young children, an annual duct inspection alongside your regular AC maintenance visit is the most efficient way to keep both the equipment and the air quality in check.

Air duct cleaning

Professional cleaning of your full duct system removes accumulated pollen, dust, and debris. We inspect seals and connections on the same visit to ensure no conditioned air is escaping into wall cavities. View our duct cleaning service.

Indoor air quality

UV germicidal lamps, HEPA media filters, and air scrubbers installed inside your air handler treat every room simultaneously. Effective for Lake Mary households where allergies, pets, or young children make air quality a priority. View our indoor air quality service.

From Carrier and Trane to Lennox and Daikin, we repair, maintain, and install all major heating and cooling brands across Lake Mary and Seminole County.

Frequently asked questions about HVAC services in Lake Mary

How quickly can you get to me in Lake Mary?
For most service calls across Lake Mary and Heathrow, we can reach you the same day. For urgent AC failures during summer, we prioritise the call and aim to arrive within two to three hours. Call (689) 326-7373 to confirm availability for your address.
Do you work with HOA requirements in Lake Mary and Heathrow?
Yes. We’re familiar with the HOA guidelines common in Lake Mary and Heathrow communities, particularly around outdoor unit placement, equipment screening, and exterior modifications. We can advise on compliant installations before any work starts.
My newer AC system is running but the house isn’t reaching temperature. What could cause that?
Common causes in newer Lake Mary homes include incorrect thermostat configuration, refrigerant charge that has drifted from the factory spec, dirty evaporator coils, or duct leaks into unconditioned spaces. An annual maintenance visit typically catches all of these. If the system is short-cycling or the bill is unusually high, a calibration visit is often enough to resolve it without replacing any components.

About Lake Mary, Florida

Lake Mary sits in northern Seminole County along the I-4 corridor between Sanford and Longwood, and has grown since the 1990s into one of the most desirable suburban communities in Central Florida. The International Parkway corporate park corridor draws a significant professional population, and the residential neighbourhoods that developed alongside it, including Heathrow and the communities along Lake Mary Boulevard, tend to have newer, better-insulated homes than much of the surrounding area. Lake Mary’s development largely took place after Florida’s building codes were upgraded in the late 1980s, meaning HVAC systems here are generally more efficient than those in older Seminole County cities.

That newer construction, however, brings its own HVAC considerations. Systems that were correctly sized for a home’s original layout can drift out of calibration after years of use, causing short-cycling, humidity issues, and higher energy bills. The inland location spares Lake Mary from the salt-air corrosion seen on the Volusia County coast, but Florida’s summer heat and humidity are consistent, and a well-maintained system is the difference between a comfortable home and a $300 monthly electric bill. Heathrow’s gated communities and the HOA-managed neighbourhoods throughout Lake Mary also add considerations around outdoor unit placement and equipment modifications.

If you’re looking for a heating and air conditioning company near you in Lake Mary or Heathrow, Premier Frost covers all of Lake Mary and Seminole County. Call us at (689) 326-7373 for same-day service and free estimates on all installations.
