One of the most common questions we hear from homeowners in Gwinnett County is some version of: "How often do I actually need to get my HVAC serviced?" It's a fair question. Maintenance visits cost money, and it can be tempting to skip them when the system seems to be running fine. But in Georgia's climate — with long, hot summers and mild but real winters — your HVAC system works hard almost year-round. Regular maintenance isn't just a nice-to-have here. It's what keeps your system running efficiently, extends its lifespan, and prevents the kind of breakdowns that always seem to happen at the worst possible time.
The Short Answer: Twice a Year
For most homes in Georgia, HVAC maintenance should be scheduled twice a year — once in the spring before cooling season, and once in the fall before heating season. This two-visit schedule gives your technician the opportunity to inspect, clean, and tune up each major component of your system before it faces peak demand. Spring maintenance focuses on your air conditioning and cooling system. Fall maintenance focuses on your heat pump or furnace.
If you're on a maintenance plan with Henson Heating Air and Plumbing, these visits are automatically scheduled and you receive priority service, discounts on repairs, and reminders so you never have to think about it.
Why Georgia's Climate Makes Regular Maintenance Even More Important
HVAC systems in states with mild climates get a break during shoulder seasons. In Georgia, that break is much shorter. Gwinnett County homeowners routinely run their air conditioning from April through October — sometimes longer. That's six or more months of near-continuous operation for your cooling system. Then your heating system picks up for several months. The result is significantly more wear on your equipment than you'd see in a milder region.
High humidity also plays a role. Georgia's humidity puts extra stress on evaporator coils, condensate drain lines, and the overall moisture management of your system. A dirty or partially clogged drain line that might go unnoticed in a drier climate can cause water damage and mold growth quickly in a humid environment like ours. Regular maintenance catches these issues early.
What's Included in a Professional HVAC Maintenance Visit
A thorough maintenance visit from a qualified technician covers far more than just changing the filter. At Henson Heating Air and Plumbing, our maintenance visits include a complete inspection of all major components.
For Your Air Conditioning System
During a spring AC tune-up, we check and clean the evaporator and condenser coils, measure refrigerant levels and check for leaks, test electrical connections and components including capacitors and contactors, inspect and clean the condensate drain line, check static pressure and airflow, lubricate moving parts, verify thermostat calibration, and inspect the overall condition of the system. This comprehensive review gives us a clear picture of your system's health and lets us catch small problems — a slightly low refrigerant level, a capacitor showing early signs of wear — before they become breakdowns.
For Your Heating System
During a fall heating tune-up, we inspect and test the heat exchanger for cracks (critical for safety with gas furnaces), test ignition components, check gas pressure and burner operation, inspect the flue and venting, test safety controls, clean burners and heat exchanger surfaces, and verify heating output and airflow. For heat pump systems, we check refrigerant levels and inspect the reversing valve and auxiliary heat strips in addition to all standard checks.
What Happens If You Skip Maintenance?
Skipping a maintenance visit occasionally won't immediately destroy your system, but patterns of skipped maintenance tend to lead to predictable outcomes. Dirty coils reduce efficiency and eventually cause the system to work harder than it should. Low refrigerant — from a slow leak — goes undetected until the system stops cooling. Worn capacitors fail unexpectedly on the hottest day of the year. A cracked heat exchanger goes undetected, which is a carbon monoxide risk in gas furnace systems. None of these scenarios are hypothetical — they're exactly what we see when systems haven't been maintained.
Beyond safety, there's a financial case. A well-maintained system runs more efficiently, which means lower utility bills month after month. And a system that receives regular care will typically last 15–20 years, while a neglected system may need replacement after 10–12 years. For a system that costs $5,000–$12,000 to replace, that extended lifespan is significant.
Should You Get Maintenance More Than Twice a Year?
For most homeowners, two visits per year is the right cadence. However, there are situations where more frequent check-ins make sense. If your system is older (10+ years), if you have pets that shed heavily and clog filters faster, if anyone in the home has respiratory issues or allergies that make indoor air quality a priority, or if your home is larger and places higher demands on the system, an additional check-in may be worthwhile. We're happy to help you determine the right schedule for your specific situation.
When's the Best Time to Schedule?
For spring AC maintenance, we recommend scheduling in February or March — before the heat season hits and before our schedule fills up. By April and May, most HVAC companies in Gwinnett County are running full schedules as homeowners realize their AC isn't working after the first hot week. Scheduling early means you get your pick of appointment times and aren't scrambling during a heat wave.
For fall heating maintenance, September or October is ideal — before the first cold snaps arrive and before heating season demand picks up. This timing also gives you time to address any repairs before you actually need the heat.
