When the summer heat hits Houston, you need your air conditioning system to run efficiently, reliably, and affordably. At Abacus Plumbing, Air Conditioning & Electrical, we know firsthand how vital a well-maintained AC system is to your comfort, safety, and budget. With energy costs rising and HVAC systems becoming more advanced in 2025, it’s more important than ever to stay on top of your air conditioning maintenance.
Whether you live in The Heights, Sugar Land, Katy, or anywhere across the Houston metro area, here are essential AC maintenance tips that every Houston homeowner should know this year.
Houston’s air is filled with allergens like pollen, dust, and mold spores. If your air filter is clogged, it restricts airflow and makes your system work harder, leading to higher energy bills and poor indoor air quality.
In Houston’s humid climate, change your filter every 1–2 months, especially during peak usage seasons. If you have pets or allergies, you may want to check it monthly.
Leaves, pollen, and Gulf Coast debris can build up around your outdoor condenser unit. This blocks airflow and reduces efficiency—especially during Houston’s long cooling season.
Turn off the power to the unit.
Clear leaves and debris from around the condenser.
Gently rinse the unit with a hose (never use a pressure washer).
Keep shrubs or grass trimmed back at least 2 feet.

Higher-than-normal electric bills

Humidity is no stranger to Houston. Your AC’s drain line removes moisture, but if it gets clogged, it can lead to leaks, mold growth, and even water damage inside your home.
Pour a cup of vinegar down the condensate drain every 2–3 months.
Check for signs of moisture around your indoor unit.
If there’s a backup, call Abacus for immediate service.
Houston’s hot, humid weather means your AC has to work overtime. Poor insulation or drafty windows can make the job even harder—and more expensive.
Add weather stripping around doors and windows
Use curtains or blinds to block direct sunlight
Seal any ductwork leaks
Insulate attics and crawlspaces to keep cool air in
Our team at Abacus can assess your home’s energy efficiency and help with insulation, duct sealing, and more.
A spike in your electricity bill might mean your AC is losing efficiency or failing. With Houston's high summer energy usage, monitoring is key.
Track your utility bills for unusual spikes
Consider smart home energy monitors
Schedule a system checkup if bills climb unexpectedly
An underperforming AC system can cost you hundreds each year—let Abacus help diagnose and fix any performance issues early.
In Houston homes, it’s common to rearrange furniture without thinking about airflow. Blocked vents can cause uneven cooling and put strain on your system.
Walk through your home and make sure all vents are open and unobstructed.
Dust and vacuum vents monthly to keep airflow steady.
If your system is over 10–15 years old, it may be time to upgrade. Today’s air conditioners are significantly more efficient and built for Houston’s demanding climate.
Lower monthly energy bills
Quieter, more consistent cooling
Smart technology integration
Houston energy rebates or tax incentives
