Just like a car, your HVAC system needs regular maintenance. Here are a few must-do items for keeping it running efficiently:
- Change air filters every 1–3 months. Dirty filters restrict airflow and force your system to work harder.
- Schedule annual maintenance. A licensed HVAC professional should inspect and service the system every year—cleaning coils, checking refrigerant levels, and calibrating the thermostat.
- Keep outdoor units clear. Remove leaves, weeds, and debris around the exterior unit to allow for proper airflow.
- Check the condensation line. Especially in humid climates like Florida, clogged lines can lead to water damage inside the home.
The Lifespan of HVAC Units in Florida
On average, HVAC units in Florida last 10 to 15 years, though some well-maintained units can go longer. If you’re a buyer, be cautious of units over 12 years old—especially if there’s no clear maintenance history.
If you’re a seller, you may want to consider getting the system serviced or inspected prior to listing the home. Buyers are much more confident when they see a clean inspection report or recent service receipt.
Refrigerant Standards: R-22, R-410A, and Now R-454B?
One major factor when dealing with older HVAC units is the refrigerant they use.
- R-22 (Freon) was banned from production in the U.S. as of January 1, 2020. While still legal to use, R-22 is expensive and increasingly scarce. Most units that use R-22 are now over 15 years old.
- R-410A (Puron) replaced R-22 as the standard refrigerant for the past two decades. While much safer for the environment, it is now being phased out starting in 2025, due to its global warming potential.
- R-454B and other low-GWP refrigerants are the next generation. These refrigerants are more environmentally friendly but require new HVAC equipment designed to handle them.
🔧 What This Means for Buyers and Sellers:
- If the unit uses R-22: Expect higher service costs. If the unit fails, it may not be cost-effective to repair.
- If it uses R-410A: Parts and refrigerant are still available, but HVAC professionals may start pushing for upgrades after 2025 as newer refrigerants come to market.
- If buying a new unit: Ask your contractor what refrigerant it uses and how future-proof it is.
Red Flags and Smart Questions to Ask
If you’re evaluating a home with an older HVAC system, consider these tips:
Buyers:
- Ask for the age and service history of the HVAC unit.
- Find out what refrigerant it uses.
- Consider negotiating a home warranty or credit for future replacement.
Sellers:
- If your system is older but working, get a service inspection and document it.
- Consider offering a one-year home warranty covering HVAC to ease buyer concerns.
- Be upfront. A unit that’s 15+ years old may not add value but disclosing its condition can prevent surprises during inspection.
Final Thoughts
The HVAC system plays a crucial role in both the comfort and cost of homeownership—especially in a climate like Florida’s. With new refrigerant standards on the horizon and many older systems still in use, it’s more important than ever to be informed.
Whether you’re buying or selling, understanding the age, condition, and refrigerant type of your HVAC unit can help you make smarter decisions—and avoid costly surprises.
