AC Repair

Your AC works hard to keep you comfortable so make sure it gets the care it needs. If you notice any of the following problems, give our HVAC experts a call to schedule AC repair. 

  • No air or low airflow
  • Only hot air
  • Bad smells from vents
  • Leaking unit
  • Burning smell
  • Overcycling
  • Random shutdowns

AC problems might seem like a minor inconvenience but even a small problem can significantly raise your cooling bills and lead to further damage. It’s in your best interest to call a professional as soon as you notice a problem. 

AC Replacement

Eventually, your air conditioning will wear down and will require replacement. When that time comes make sure you work with the experts at Southern Air. We can help you find energy-efficient replacements that fit your needs and budget. 

Old HVAC equipment becomes less efficient and suffers breakdowns more frequently, and repairing an older system starts to have diminishing returns. After a certain point, it makes more sense to replace your old HVAC rather than pay for frequent repairs. 

As a general rule of thumb, it’s worth replacing your AC if repair costs are at least 50% of the cost of replacement. In that case, buying a new AC will probably be the most financially efficient in the long term. 

Furnace Repair & Replacement

Your furnace is the other half of your HVAC system and works to keep you and your family warm during the cold months. Just like your air conditioner, your furnace needs regular maintenance and care. Common signs you need furnace replacement include:

  • No hot air
  • Uneven heating
  • Burning or gas smell
  • Yellow pilot light flame
  • Random shutdowns
  • Excess soot or dust

We also offer comprehensive furnace and heater replacement. We work with the top brands in the industry to source high-quality products and we will handle every aspect of the installation, from removing the old heater to performing final inspections and testing. You can count on us for fast and reliable work!

HVAC Service FAQ

Below are some of the most common questions we receive about our HVAC services in San Mateo, FL. 

How Often Should I Get HVAC Maintenance?

You should get professional HVAC at least once every 12 years—preferably once every six months. The more frequently you get maintenance, the lower the risk of breakdowns and the less you’ll spend on HVAC repair. 

What Does HVAC Maintenance Involve?

Your checklist might differ, but the typical HVAC maintenance appointment will involve the following tasks:

  • Changing HVAC filters
  • Testing electrical components
  • Cleaning AC coils
  • Flushing drain lines
  • Calibrating thermostats
  • Testing system pressure
  • Cleaning ductwork
  • Checking refrigerant levels

What Is the Typical AC and Furnace Lifespan?

The typical lifespan of a residential air conditioner and furnace is about 15 and 20 years, respectively. Your HVAC systems will last longer if you get regular maintenance. 

What’s the Best Temperature for My HVAC?

The best temperatures for your HVAC are 78 degrees in the summer and 68 degrees in the winter. It is also better to keep your HVAC on during the day while at home rather than switching it on and off when you need it.

We have been consistently happy with knowledge and service from Southern Air. We appreciate you, Robert!
Response from the owner: Thank you so much for your 5 Star review patricia!
WOW..this company is top notch. Unfortunately I Had to have new AC installed because mine was giving up it's ghost. Two professional looking men showed up and went to work right away . AC works excellent ! And they cleaned everything up when they were done...Highly recommend you call if you need any work done....Thank you
Response from the owner: Thank you so much for taking the time to leave us a positive review - it’s greatly appreciated!
Jason was pleasant, professional and very straightforward. He showed us the very rusty and corroding coils and said we could keep repairing the 22 year old AC but it would be a waste of money and an ongoing and potentially hazardous decision. We are proceeding with a new AC based on his recommendation.
Response from the owner: Thank you for taking the time to share your review with us!
