for furnaces, heat pumps and electric heat, so your home is ready when temperatures dip. We install and service

heat pumps, ductless systems, and more

for homes of every age and layout, along with indoor air quality solutions and duct cleaning.

Why Largo Homeowners Choose a Local Air Conditioning Company

A local air conditioning company means shorter drive times and quicker help when your system quits on a July afternoon. We provide

fast response across Largo neighborhoods

from homes near Largo Central Park to communities along Ulmerton Road, East Bay Drive and Seminole Boulevard. Our team is made up of

technicians who know Florida’s climate

and understand how constant heat, humidity and nearby salt air wear on outdoor equipment.

Air Conditioning Repair and Installation in Largo, FL

Your air conditioner works harder in Pinellas County than almost anywhere in the country, so repairs and replacements need to be done right the first time.

AC Repair in Largo

If your AC is blowing warm air, short cycling, leaking water or making grinding noises, our technicians find the cause and explain your options before any work begins. We provide AC repair on all major makes and models, and our stocked trucks let us finish many repairs in a single visit.

AC Installation and Replacement in Largo

When your system is aging or can’t keep up, we size a new air conditioner to your home’s actual cooling needs instead of simply matching the old unit. As a Trane Comfort Specialist, we handle every step of your AC installation, from equipment selection to startup. We can also walk you through financing options and any manufacturer rebates currently available.

HVAC Maintenance in Largo, FL

Routine maintenance helps your system run efficiently through Largo’s long cooling season and catches small problems before they turn into breakdowns.

AC Maintenance and Tune-Ups

Our AC maintenance follows a detailed checklist, so you know exactly

what’s included in an HVAC maintenance visit

before we arrive. We check refrigerant levels, temperatures and pressures, clean the coil and condensate drain line, inspect electrical connections and test airflow at the supply and return. A common question is

how much does AC maintenance cost in Largo, FL?

Pricing depends on your system and whether you join a maintenance plan, and new customers can currently book a $69 seasonal tune-up. If you’re unsure

how often you should service your AC in Florida

, plan on twice a year, since ENERGY STAR recommends a cooling checkup each spring and a heating checkup each fall, and Florida systems run for most of the year.

Furnace Tune-Ups Before the Cooler Months

Largo’s winters are mild, but heating equipment can sit unused for months while dust settles on heat strips and burners. A fall tune-up lets us test safety controls, check the electric heat and confirm your thermostat calls for heat correctly before the first cold front arrives.

Heat Pump Services in Largo, FL

A heat pump cools your home in summer and heats it in winter from one system, which makes it a popular choice across Pinellas County.

Home Heat Pump Installation

Before we recommend new equipment, we help you answer one question:

Is a heat pump right for your Largo home?

For many homes that already use electric heat, the answer is yes, because a heat pump moves heat rather than creating it, and the U.S. Department of Energy notes it can cut heating electricity use by roughly 50% compared with electric resistance heat. That advantage drives

heat pump efficiency in a mild Florida winter

, when outdoor temperatures rarely drop low enough to lean heavily on backup heat strips. Our heating installation team sizes the system to your home and can help you look for available heat pump rebates.

Heat Pump Repair

Because a heat pump runs nearly year round in Florida, small problems show up quickly. Common

signs your heat pump needs repair

include warm air in cooling mode, cool air in heating mode, ice that stays on the outdoor coil, nonstop running and a sudden jump in your power bill. Our heating repair technicians check the reversing valve, defrost controls, refrigerant charge and compressor to pinpoint the cause.

Heating and Furnace Repair in Largo, FL

Whatever type of heat your home has, our team can diagnose and repair it.

Heater and Furnace Repair

We handle

gas furnace repair

for ignition, flame sensor and blower problems, along with

electric heat strip and air handler repair

for the many Largo homes that rely on electric backup heat. Some of the most

common heating problems in Largo homes

include a burning smell that lingers after the first startup of the season, breakers that trip when the heat strips engage, a blower that runs without producing warm air and a thermostat that calls for heat with no response. If you ever smell gas, leave your home and contact your gas utility before calling us for furnace repair.

Furnace Replacement in Largo

When a furnace or heating system reaches the end of its life, we size and install a replacement heating system that fits your home and budget. If you’re facing the question of

repair or replace, and how to decide

, start with age and repair cost. As a general guideline, a system older than about 10 years that needs a repair costing more than half the price of a new unit is usually a better candidate for replacement, and repairs up to $750 can count toward a new system if you upgrade within 90 days.

Ductless Mini Split Installation in Largo, FL

Ductless mini splits deliver cooling and heating to individual rooms through a compact indoor unit connected to an outdoor unit, with no ductwork required.

Where Ductless Systems Work Best

A ductless mini split is a strong fit for

additions, garages, and sunrooms

where extending existing ducts would be costly or the main system can’t keep up with the extra space. It also works well in

homes without existing ductwork

, since each zone gets its own thermostat and there are no duct runs to lose energy. According to the U.S. Department of Energy, duct losses can account for more than 30% of the energy used for space conditioning, especially when ducts run through a hot attic.
