Spring AC Tune-up in Apex, NC

February or early March. Not April, and definitely not May. Here's why timing matters more than most homeowners realize in the Triangle.

The Raleigh-Durham area doesn't follow the neat seasonal calendar that HVAC advice articles assume. Those articles are written for places where spring means 60s and 70s and AC season starts in June. In the Triangle, March regularly hits 80°F. April almost always does. By the time most people think "I should get my AC checked," they're already running it daily and competing with every other homeowner who had the same thought.

Our scheduling in February and early March is wide open. We can usually offer same-day or next-day appointments. By mid-April, we're booking three to five days out. By May, wait times stretch to one to two weeks. And if your tune-up reveals a repair need, add parts ordering and a return visit on top of that wait.

Getting ahead of the rush isn't just about convenience. It's about having time to fix problems before you need the system.

What a Spring AC Tune-Up Covers

Your AC or heat pump has been sitting in cooling standby since last September or October. Here's what six months of downtime can do, and what our techs check for:

Refrigerant Charge

Refrigerant doesn't "burn off" or get "used up" — it circulates in a sealed system. If the charge is low, there's a leak. Even a slow leak that loses a pound of refrigerant over a season forces your compressor to work harder, reduces cooling capacity, and can lead to compressor failure if ignored long enough. We measure refrigerant pressures and compare them to manufacturer specifications. If the charge is low, we find the leak, repair it, and recharge.

Electrical Components

Capacitors are the most common AC failure point, and they weaken over time. A capacitor that measured at 40 microfarads last year might test at 34 this spring. The compressor will still start, but it's working harder to do it. We test capacitors, contactors, and relay switches and replace any that are out of spec before they fail on the hottest day of July.

Condenser Coil Cleaning

Your outdoor unit sat through fall leaves, winter debris, and spring pollen. The condenser coil fins are almost certainly partially blocked. Even 20% blockage reduces your system's ability to reject heat, which means longer run times and higher energy bills. We clean the coil with a coil cleaner and low-pressure water, straighten bent fins, and clear debris from the unit's surroundings.

A note specific to the Triangle: our pollen season coats outdoor units in a visible yellow-green film. This isn't just cosmetic. Pollen is sticky and traps additional dirt on the coil surface. A post-pollen cleaning in late May is worth doing if your tune-up happens before pollen season peaks.

Condensate Drain

The indoor portion of your AC removes humidity from the air, and that moisture drains through a condensate line. Over the winter, algae, mold, and debris can build up in the line. A clogged condensate drain causes water to back up into the drain pan and potentially overflow — damaging ceilings, walls, and flooring. In humid Triangle summers, a well-functioning condensate drain removes 5-20 gallons of water per day. We flush the line with a cleaning solution and verify proper drainage.

Evaporator Coil Inspection

The indoor coil is where heat exchange happens. A dirty coil reduces cooling capacity and can freeze over, blocking airflow completely. We inspect the coil for dirt buildup, mold growth, and any signs of corrosion.

Thermostat Calibration

We verify your thermostat reads accurately and cycles the system properly in cooling mode. A thermostat that's off by even 2-3 degrees can cause short cycling or overcooling, both of which waste energy.

Air Filter

We replace the filter as part of every tune-up. If you haven't changed it since fall, it's overdue. A restricted filter is the single easiest problem to prevent and the most common cause of reduced performance.

What We Find Most Often in Spring

After thousands of spring tune-ups in the Triangle, the most common findings break down like this:

Dirty condenser coils — nearly every system, every year. This is just Triangle life with our pollen and tree cover.

Weak capacitors — about 1 in 5 systems. These are cheap to replace proactively ($75-150) and expensive to deal with as an emergency ($200-350 with a service call fee on a weekend).

Low refrigerant — about 1 in 8 systems. Usually a slow leak at a service valve or a brazed joint. Caught early, the repair is straightforward. Ignored for a season, it can damage the compressor.

Clogged condensate drains — about 1 in 6 systems. A $20 problem during a tune-up, a $500+ water damage problem if it backs up in July.

The $49 Spring Tune-Up

Our spring AC tune-up is $49 and covers everything above. If we find a repair need, we provide a written quote on the spot — you decide whether to proceed. Same-day scheduling is available through early March for homes in Apex, Cary, Raleigh, Durham, Holly Springs, and Fuquay-Varina.

The best time to find out your AC has a problem is in February, when no one needs their AC and we have all the time in the world to fix it. The worst time is in July, when everyone needs their AC and we're triaging emergencies. Schedule now and get ahead of the season.
