MAINTENANCE
The technicians who respond to your 2am emergency call are the same ones who do your annual tune-up. We'd rather see you in April and catch a failing capacitor on our schedule than come out in July on yours. Schedule maintenance before summer.

The outdoor condenser coil rejects heat from your home to the outside air. When it's coated with dirt, pollen, and debris — which happens fast in Alabama — heat rejection efficiency drops and the compressor works harder. We clean the coil thoroughly, not just hose it down.
Capacitors degrade gradually before they fail completely. A capacitor at 60% of rated capacitance is on borrowed time. We test the actual capacitance and flag components that are degrading. Replacing a weak capacitor during maintenance prevents the 10pm emergency call.
We check suction and discharge pressures against manufacturer specs. Low pressure indicates a refrigerant leak. Running low on refrigerant strains the compressor and reduces cooling capacity. Catching it during maintenance versus when the system fails is a significant cost difference.
The condensate drain removes water pulled from your indoor air. In Alabama's humidity, these drains clog with algae growth regularly. A clogged drain causes water backup into the air handler or attic — and that's expensive water damage. We flush and treat the drain on every maintenance visit.
Vibration, heat cycles, and corrosion loosen and degrade electrical connections over time. We check all terminals, wiring, and connections for signs of wear. A loose connection that arcs can damage control boards that cost several hundred dollars to replace.
Fall maintenance visits include igniter testing, heat exchanger visual inspection, burner cleaning, flue inspection, and safety control testing. A cracked heat exchanger that gets caught during maintenance is far better than one discovered after a carbon monoxide incident.
Why Alabama HVAC Needs More Attention
Birmingham's climate puts more stress on HVAC systems than most of the country. The cooling season runs from April through October — seven months of sustained demand. Outdoor temperatures regularly hit 95-98 degrees in July and August. Humidity sits above 70% for months at a time. These conditions accelerate component degradation in ways that maintenance intervals designed for northern climates don't account for.
Condenser coils in Birmingham collect pollen, cottonwood, and red clay dust at a rate that justifies cleaning twice a year — spring and fall — rather than the once-annual recommendation on most equipment spec sheets. Capacitors in outdoor units baking in direct afternoon sun fail sooner than the average. Condensate drains clog with algae growth in weeks during humid summer months.
We schedule maintenance visits with Alabama's climate in mind, not a generic national standard.
The best time to call for spring maintenance is March through mid-April. By late May, we're fielding emergency calls and our schedule fills fast. If you want a scheduled daytime appointment at a convenient time, call early. If you wait until June, you may be waiting.
DIY vs. Professional Maintenance
There are tasks you can and should do yourself:
- Change the air filter monthly during cooling season (every 1-3 months during winter)
- Keep plants, shrubs, and debris 18-24 inches away from the outdoor unit
- Pour diluted bleach (1 cup bleach to 1 gallon water) down the condensate drain access port monthly
- Keep the outdoor unit fins clear of leaves and debris after storms
- Check that supply and return vents aren't blocked by furniture
What requires professional tools and training:
- Coil cleaning with proper chemicals and pressure (improper cleaning damages aluminum fins)
- Refrigerant pressure testing (requires gauges and EPA 608 certification)
- Capacitor testing and replacement (live voltage hazard)
- Heat exchanger inspection (requires combustion analyzer and proper knowledge)
- Electrical testing of contactors, control boards, and wiring
Maintenance FAQ
When should I schedule AC maintenance in Birmingham?
March or April. Before summer demand starts and our schedule fills with emergency calls. Heating maintenance should be scheduled in October before the first cold snap.
How often should I get HVAC maintenance?
At minimum, once a year in spring for the cooling system. We recommend twice a year in Alabama — spring for cooling and fall for heating — given the climate demands on equipment here.
My system seems to be working fine. Do I still need maintenance?
Yes. Most failures show precursor symptoms that a technician can spot and address before the system fails. A capacitor at 60% rating works fine until the day it doesn't. By the time you notice the system isn't cooling properly, the damage is often done.
How long does a maintenance visit take?
A thorough maintenance visit for a single-system home typically takes 60-90 minutes. Multi-system homes take longer. We don't rush through a checklist — we actually look at what we're cleaning and testing.
What if you find something wrong during maintenance?
We tell you what we found, explain what it means, and give you a repair quote before doing anything. If it's a failing capacitor that we caught early, we'll explain the risk of waiting versus replacing it now. The decision is always yours.
