Summer HVAC Mistakes 2025: 5 Costly Errors and How to Avoid Them
Summer HVAC Mistakes 2025 are more common than most homeowners realize, and they often lead to expensive repairs or complete system failure. With longer heatwaves and increased demand on cooling systems, it’s important to give your HVAC unit the care it needs to stay efficient and reliable all season long.
Whether you’re in Troy, Clifton Park, or nearby areas in New York, Glamorgan Heating & Cooling is here to help you avoid these mistakes and keep your home cool and comfortable throughout summer 2025.
1. Skipping the Annual Tune-Up
Neglecting professional maintenance is one of the top Summer HVAC Mistakes 2025. Annual tune-ups identify wear-and-tear, prevent refrigerant leaks, and improve efficiency. Glamorgan technicians provide full-system inspections, including coil cleaning, airflow testing, and thermostat calibration to ensure your AC is summer-ready.
Skipping tune-ups can void manufacturer warranties, reduce system lifespan, and lead to surprise breakdowns during heatwaves. A small service fee now can prevent a costly repair later.
2. Setting the Thermostat Too Low
Cranking the thermostat below 68°F doesn’t cool your home faster, it only makes your system work harder. The best range for comfort and efficiency is 72–75°F. Pairing this with a programmable or smart thermostat helps manage temperature schedules and avoid energy spikes.
If you’re not home during the day, consider raising the temperature a few degrees and letting your system gradually cool before you return. This strategy helps reduce operating time and lowers your electricity bill.
3. Ignoring Dirty Filters
Air filters should be cleaned or replaced every 1–3 months, especially during high usage periods. Clogged filters reduce airflow, trap pollutants, and overwork your HVAC unit. Glamorgan helps homeowners choose the right filters and set up a maintenance schedule tailored to their lifestyle.
Clean filters also help protect your indoor air quality, especially important for homes with pets, allergies, or young children.
4. Blocking Air Vents and Registers
Placing furniture or curtains over vents causes uneven cooling and energy waste. During service visits, our team ensures all vents are unobstructed for maximum airflow. Even small blockages can significantly reduce system efficiency and indoor comfort.
Make it a habit to check that all air vents are open and free of obstructions at the start of each season.
5. Delaying Repairs and Ignoring Warning Signs
Buzzing, rattling, poor airflow, or warm air from your vents are all red flags. One of the most expensive Summer HVAC Mistakes 2025 is waiting too long to fix small issues. Early intervention helps prevent breakdowns and protects your unit’s most important components.
If something sounds or feels unusual, don’t wait. A quick check from our team can save you from a full system replacement later.
6. Not Using Fans to Support Your AC
Ceiling and box fans help circulate cooled air, reducing strain on your AC unit. This balances indoor temperatures and allows you to raise your thermostat setting without sacrificing comfort. Using fans wisely can reduce cooling costs by up to 10 percent.
In two-story homes, try using fans to direct cool air upstairs where it’s often warmer during the day.
7. Forgetting to Clear the Outdoor Unit
Leaves, dirt, and grass clippings can block the outdoor condenser unit and reduce airflow. Make sure there’s at least two feet of clearance around the unit and schedule a summer cleaning if buildup has occurred. This helps your system breathe better and run more efficiently.
A simple hose rinse and light brushing can make a big difference in keeping your unit clean between visits.
