When to Service Your Air Conditioning Unit

If you live in Huntsville, Alabama, you already know what June feels like. Temperatures push into the mid-90s, humidity makes it feel hotter, and your air conditioner runs for hours at a stretch. That's not the time to find out your system is due for service.

The good news: a little maintenance at the right time keeps your AC running at peak efficiency all summer. Here's what Huntsville homeowners need to know.

Service Your AC Before Cooling Season Starts

The best time to schedule AC service in North Alabama is late February through April — before the heat sets in and before every HVAC company in town is slammed with emergency calls.

Why does timing matter? When you book early, you get appointment flexibility on your schedule. A technician can catch small problems — like a failing capacitor — before they turn into emergency breakdowns on a 95-degree Saturday. And a cleaned, tuned system uses less energy from day one, which means lower electric bills during the months you run it most.

If you missed the spring window, don't wait until next year. A mid-summer tune-up is still worth doing. Your system will thank you before peak heat arrives.

How Often Should You Schedule Service?

Once a year, at minimum. Most HVAC manufacturers, including Daikin, recommend annual preventive maintenance to keep your warranty valid and your system operating correctly.

If you have a heat pump that runs year-round for both heating and cooling, twice-yearly service makes sense — once in spring before cooling season and once in fall before heating season.

Durham Service Company is a Daikin Comfort Pro authorized dealer, which means our technicians are factory-trained on Daikin equipment. If you have a Daikin system, servicing with an authorized dealer keeps your manufacturer warranty intact.

Signs Your AC Needs Service Right Now

Don't wait for your annual appointment if you notice any of these warning signs.

Warm air from the vents. Your system is running but not cooling. This points to a refrigerant issue, a failing compressor, or a thermostat problem — none of which fix themselves.

Weak airflow. If the air coming out of your vents feels like a whisper instead of a strong flow, you may have a clogged filter, a failing blower motor, or ductwork issues.

Strange noises. Grinding, banging, or squealing sounds mean mechanical parts are wearing out. Catching them early is always cheaper than waiting.

Short cycling. If your AC turns on and off every few minutes instead of running full cycles, something is wrong. It wastes energy and stresses the equipment.

Water pooling near the unit. A small amount of condensation is normal. A puddle of water indoors or near your air handler is not — you likely have a clogged condensate drain.

A spike in your electric bill. If your usage habits haven't changed but your bill jumped, your AC is working harder than it should to do the same job.

What Happens During an AC Tune-Up?

A professional AC service visit from Durham includes a full inspection and cleaning of your system. Our technicians check refrigerant levels and look for leaks, clean the condenser coils on the outdoor unit, inspect the evaporator coil indoors, and test all electrical connections and capacitors. They also lubricate moving parts, check thermostat calibration, inspect and clean the condensate drain, check your air filter, and measure airflow and system pressures.

The goal is to catch anything that could cause a breakdown and confirm your system is running as efficiently as possible going into the hottest months of the year.

Don't Forget Your Air Filter

This one is on you, not your HVAC technician. Changing your air filter is the single simplest thing you can do to keep your AC healthy.

In Huntsville's hot summers, when your system runs constantly, check your filter every 30 days. A standard 1-inch filter typically needs replacing every 30-60 days during peak season. A thicker media filter may last 90 days, but check it anyway.

A dirty filter restricts airflow, makes your system work harder, and can eventually cause the evaporator coil to freeze — turning a $10 filter into a much more expensive service call.

The Cost of Skipping Service

Skipping annual maintenance doesn't save money. It moves costs around — from a predictable tune-up fee to an unpredictable emergency repair, often at the worst possible time.

According to the Department of Energy, a well-maintained air conditioner uses significantly less energy than a neglected one. In Huntsville, where cooling accounts for a large share of your summer electric bill, that efficiency gap adds up across the season.

Beyond energy costs, unaddressed issues shorten your system's lifespan. A quality Daikin system, properly maintained, can last 15-20 years. Neglect can cut that to 10.
