If your system is over 10 years old, needs frequent repairs, or struggles to keep your home comfortable, replacement may be more cost-effective. We would be more than happy to provide our expert opinion if this sounds like your system. Call or schedule your appointment today.

Absolutely. We respond quickly, often within the hour. We have technicians local to Gainesville, Lady Lake, Ocala and Melbourne ready to solve your needs.

Air Conditioning

Possible causes include refrigerant leaks, dirty filters, or coil issues. Have your system inspected by a professional.

Replace the air filter, clean coils, unclog the condensate drain, and clear debris around the outdoor unit.

Turn off the breaker, press and hold the reset button for five seconds, then restore power.

If repair costs exceed half the cost of a new unit or your system is over 15 years old, replacement is often the better choice.

Maintain your AC, use fans, improve insulation, and adjust the thermostat when away from home.

A new AC provides improved comfort, lower energy bills, quieter operation, and enhanced indoor air quality.

Heating

High bills, uneven heating, odd smells, noises, or constantly adjusting your thermostat indicate it’s time for service.

Most experts recommend maintenance at least once per year — ideally before the cooling and heating seasons begin. Regular tune-ups improve efficiency, prevent costly repairs, and extend your system’s lifespan. At Mid-Florida Heating & Air, we have an affordable Club Maintenance plan that can ensure your HVAC system gets the proper checks it needs.

Uneven heating, strange noises, high energy bills, or frequent cycling are all warning signs that your heating system needs professional service.

If your furnace is 15+ years old, inefficient, or frequently breaking down, replacement is recommended.

Gas furnaces heat quickly and cost less to operate, while electric furnaces are easier to install and maintain.

R-22 (Freon) was phased out due to environmental regulations, making remaining supplies costly.

AFUE (Annual Fuel Utilization Efficiency) measures furnace efficiency. The higher the AFUE rating, the more energy you save.

Air Duct & Indoor Air Quality

Signs include visible dust, mold, weak airflow, or worsening allergy symptoms.

Definitely. It not only improves indoor air quality but also helps prevent fires caused by debris buildup inside ducts.

Yes. It reduces allergens, improves efficiency, lowers utility costs, and helps your HVAC system last longer.

Every 3–5 years, or more often if you have pets or allergies.

A system connected to your air handler that removes biological and chemical pollutants from your indoor air.

Yes. When installed inside your HVAC, UV-C lights kill mold and bacteria without harming people or pets.

Common symptoms include sneezing, headaches, fatigue, and musty odors.

Dust, pet dander, smoke, mold spores, VOCs, and carbon monoxide.

Yes. They remove contaminants, reduce allergies, and help your HVAC system work more efficiently.

Aeroseal is a high-performance duct sealing technology that improves airflow, reduces leaks, and enhances system efficiency.

Commercial HVAC

Yes. Mid-Florida Heating & Air designs and installs high-efficiency systems for new buildings and retrofits older ones to meet modern standards.

Poor airflow, inconsistent temperatures, and energy waste are most common. Our technicians can quickly diagnose and correct these issues.

Electrical

Common options include ambient, task, accent, and layered recessed lighting.

Many companies offer free estimates for standard electrical jobs.

A surge protector installed in your electrical panel protects appliances from voltage spikes.

A brief dim is normal, but persistent dimming indicates possible electrical issues.

Home Energy Audit

It’s a professional inspection that identifies where your home is losing energy and provides solutions to improve comfort and reduce costs.

Make sure we can access attics, crawl spaces, and HVAC systems. Keep utility bills handy for review.

Yes. We handle everything from insulation and duct sealing to HVAC upgrades for improved efficiency.

Generator

It detects power loss and automatically switches your home to generator power.

Have a professional evaluate your power needs to match the correct size unit.

Typically increases property value by 3–5% and offers added peace of mind during outages.

Plumbing & Water Heaters

It depends on household size and hot water demand. A professional can calculate the correct capacity.

Age (8–12 years for tank, up to 20 for tankless), rust, or inconsistent temperatures indicate replacement is near.

It provides on-demand hot water, saves energy, and saves space.

Avoid putting hard or fibrous foods down the drain, and flush regularly with cold water.

Typically 8–12 years. Regular maintenance, flushing, and water quality all impact lifespan.

Tankless systems are energy-efficient and provide endless hot water, making them a great choice for many Florida homes.

I recently renewed my annual service plan with Mid-Florida Heating & Air, towards the end of the life of my AC unit. When it finally failed, everyone from Ryan Oakley, my repair tech, to the great team of Derek and J'Den, my installation technicians, made the choice and process of upgrading to a new unit, a smooth and efficient process.
Response from the owner:We're delighted you had a great experience with us. Thanks for the 5-star review!

Troy Dilks is not only a very skilled master of his trade, he is also very attentive to the the needs of elderly customers. I am 93, living alone. Troy was quick to volunteer help. He noticed some problems in the attic that I can no longer tined to, and he corrected them. He noticed my bird feeders needed attention and volunteered to fill them. I told him that my grandson could take care of that, and thanked him for the offer. I hope he comes out for the next service, and highly recommend him to everyone.
Response from the owner:Thank you for the perfect rating! We're pleased to know you had a great experience.
