Since 1974, Barker’s licensed HVAC and plumbing technicians have been diagnosing and fixing the same problems in College Station homes — many of them preventable with simple maintenance. The tips below come directly from our field technicians (TACLA00029385C | MP42878), based on what they see most often in Brazos Valley homes. College Station’s heat and humidity create specific challenges for HVAC and plumbing systems that generic advice doesn’t always address — so we’ve written these tips with your home in mind.
HVAC Tips From Our Technicians
- Keep your condensate drain line clear — especially in College Station summers. Our HVAC technicians clear more clogged drain lines in the Brazos Valley than almost any other single issue. High humidity means algae and mold grow fast in condensate lines — a clogged line can back up and cause water damage to ceilings and walls before you even notice. The fix is simple: pour a solution of one part bleach to ten parts water down the drain line every 90 days during cooling season. If your drain pan already has standing water, that’s a sign the line is blocked — call us before it overflows.
- Check your attic ductwork before summer hits — not during it. Leaky or disconnected duct joints are one of the most common reasons College Station homeowners call us in July saying their AC “can’t keep up.” The system is working fine — the cooled air is just dumping into the attic instead of your living room. A quick check: go into your attic on a hot day when the AC is running. If you feel a noticeable cool breeze near a duct joint, that joint is leaking. Sealing duct leaks can reduce your cooling costs by 20–30% and takes the strain off your system so it lasts longer. Our technicians can perform a full duct inspection as part of any AC tune-up.
- A dirty air filter is the fastest way to freeze your AC in Texas heat. This is the number one self-inflicted AC problem our technicians see every summer. When a filter gets clogged, airflow drops, the evaporator coil gets too cold, and the whole system freezes up — right when you need it most. In College Station, where AC runs nearly year-round, we recommend checking your filter every 30 days and replacing it at least every 60–90 days. If you have pets or anyone in the home with allergies, replace it monthly. A $10 filter change is far cheaper than a service call in July. Not sure what filter size or MERV rating is right for your system? Call us and we’ll tell you exactly what to use.
- Replace your thermostat batteries every fall — before you need your heat. It sounds minor, but dead thermostat batteries are a surprisingly common reason homeowners call us on the first cold night of the year to say their heat won’t come on. The fix takes 60 seconds, but the service call doesn’t. Make it a habit: every fall when you change your smoke detector batteries, change your thermostat batteries at the same time. If your thermostat display is dim, flickering, or showing a low battery warning, don’t wait — a thermostat that loses power mid-cycle can cause your system to short-cycle, which puts unnecessary wear on the compressor. If you’re still having heating issues after a battery swap, our heating repair team can diagnose the problem same day.
