Heatwaves are becoming more intense and more frequent. For many, summer is no longer just hot\u2014it\u2019s dangerous. Extreme heat sends thousands of people to emergency rooms every year. It also pushes your cooling system to its limit.<\/p>\n\n\n\n
If your home isn\u2019t ready, you\u2019ll feel it fast. Temperatures can rise indoors even with the AC running, especially if it hasn\u2019t been serviced in a while. Small problems like clogged filters or drafty doors can make your system work harder and drive up your energy bill. That\u2019s why a solid checklist is key. Getting ahead of the next heatwave means more comfort, fewer surprises, and a much lower risk of your air conditioner breaking down when you need it the most.<\/p>\n\n\n\n
The first step is easy but often ignored\u2014check the weather ahead. Look at the seven-day forecast, not just the daily high. Watch for back-to-back days with temperatures above 90\u00b0F, high humidity, or poor air quality. These conditions strain cooling systems and can become unsafe, especially for seniors or small children.<\/p>\n\n\n\n
Knowing what\u2019s coming gives you time to prepare. If a heatwave is expected mid-week, don\u2019t wait to act. Supplies like filters, fans, or blackout curtains often sell out quickly. HVAC technicians also get booked fast when the heat rolls in. Planning even a few days in advance helps you avoid scrambling when it\u2019s already too hot.<\/p>\n\n\n\n
Before the hottest days arrive, call a licensed HVAC technician to inspect and tune up your system. A standard AC maintenance<\/a> visit should include checking refrigerant levels, testing the thermostat, cleaning the coils, and making sure electrical parts are in good shape.<\/p>\n\n\n\n Many breakdowns during a heatwave are caused by things a technician could have caught early. Even something as small as a loose wire or low refrigerant can stop your system from cooling properly. A tune-up once a year, ideally in late spring or early summer, helps your system run longer and reduces the chance of emergency repairs.<\/p>\n\n\n\n One of the fastest ways to help your air conditioner work better is by replacing the air filter. A clogged filter limits airflow, which makes the system less efficient. It also causes parts to overheat and can even freeze up the coils. That means less cool air coming out\u2014and more wear on your unit.<\/p>\n\n\n\n Most filters should be replaced every 1 to 3 months, especially in summer when systems run more often. If you have allergies, you may need to check them more often. Clean filters help your system cool faster and use less energy, which means more comfort and lower bills.<\/p>\n\n\n\n Hot air finds its way into your home through gaps in doors, windows, and even electrical outlets. This makes your cooling system work harder to keep temperatures down. Start by sealing gaps with weather stripping or caulk. Close unused fireplace dampers<\/a> and install door sweeps if needed.<\/p>\n\n\n\n Also, block direct sunlight. Cover windows with blinds or curtains by noon. Reflective film or blackout shades can help even more. The less heat that gets inside, the easier it is for your system to keep things cool.<\/p>\n\n\n\n Turning your thermostat as low as possible won\u2019t cool your home faster. In fact, it often wastes energy. Set it to a steady temperature\u2014ideally around 78\u00b0F when you\u2019re home and awake. When you\u2019re away, bump it up a few degrees, but don\u2019t turn it off completely.<\/p>\n\n\n\n3. Swap Out Dirty Filters<\/strong><\/h2>\n\n\n\n
