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.

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.

Commercial HVAC

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.

These guys are phenomenal! They took the old system my house came with, explained how old it was and why it needed to be updated. Yeah, not a cheap repair, but necessary in Florida! What was remarkable was our old AC died on a friday afternoon, these guys came out at 8:00 pm on Friday and worked for hours to help diagnose the issues! I highly recommend this company and David was amazing to work with! The Daikin Fit they sold me is so amazing! Thanks guys!

Where do I start. First, I want to compliment the professionalism exuded by the staff of Mid Fl I have encountered along the way. Very good company to do business with. Second, Kosha and Jacob were very efficient they worked as a team and got the job done. They were tasked with removing my 11 yo system and replacing that system with a newer and more efficient one. Upon their arrival they were ready to start and got down to business. With little hesitation they were able to install my system and answered questions I had about the process. And they were very friendly. Jacob worked efficiently without interruption. He handled his part of the assignment with ease. While Kosha attended to the other part. I must say they are well oiled machine. I am so happy with the service I received and look forward to working with you guys again. So my 5 star rating is what I think of my service I received today. Thank you so much. If you need your system repaired, replaced, or maintenance you won't go wrong.

UPDATE: October 1, 2020

Today was my six month maintenance for my system. Robert was my technician and he was thorough with the process. He informed each time he thought it was necessary. Courteous and professional. I am very satisfied with my service I received today.
