AC Repair in San Mateo, FL
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 in San Mateo, FL
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 in San Mateo, FL
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.

Southern Air is the Greatest company we've have had the pleasure of dealing with since moving to Putnam County. Our AC unit went out while I was away dealing with the passing of my mother. They were quick to respond with same day services for repair and an estimate for a new system. Jason and Jeremy were the Greatest guys ever. Southern Air should be Proud these guys were polite, courteous, and concerned for our well being with this heat. We tried another AC company, they came out once, left after speaking to me and never came back.
I love Southern Air. I'll never use any one else.
Update
April 3, 2025 and I'm still using Southern Air for all my AC needs.
Jason came out late for after hours repair and he was soo professional and Awesome. I can't praise him enough for how well he does his job. I have even bought a surge protector for my AC unit to protect it during Florida's thunder storms. I can always count on my Southern Air tech Jason to keep my AC running smoothly 👍🏽 Thank you Jason
Southern Air is a team-oriented operation w/ a deep bench of well-trained, well-motivated, wonderful technically proficient professionals, both in the field and in the office! They like what they do, they like each other, they're having fun, and it really shows!! This is a growing business that should be, if not, already, the case study focal point of college-level business operation and administration studies, locally and around the country!
07/22/25 - Today is Tuesday. This past Friday, we enjoyed our regular semi-annual check-up, and all went well; we passed the quiz!💥 Then, sometime Saturday late afternoon/early evening, things started "warming up"!
By Sunday A.M., our a/c system, a mere 2 yrs old, was failing via an oscillating blower motor on our Air Handler.
Mayday! Mayday! Mayday! Temp's are rising rapidly; we're in distress! Send Help!!
Jamar Witt, another stellar performer from Southern Air, arrived to discover our blower motor acting up, and was able to get it squared away ... sorta! About an hour later, after a full & frank discussion, it resumed it's irregular misbehavior, again. I brought Molly up to speed, another star "weekend warrior" @ Southern Air, and she relayed to Jamar who wrote the order; and we settled in for a couple toastie days, waiting for replacement parts!
Today, our parts arrived, and Jamar just departed, ~1730, having replaced our blower motor - easy-peasy! We're cooling rapidly, now, from a heat-soaked 87°!
What did we ever do before a/c? 🙄
Southern Air to our rescue, again, 24/7! 👍🇺🇲
