Tucson summers don’t play around. When those triple-digit temperatures roll in, you need your air conditioner running like clockwork. A well-maintained system makes all the difference when it feels like an oven outside. Prepping your AC before the worst of the heat hits can save you from sticky, sleepless nights and sky-high energy bills. At One Hour Heating & Air Conditioning®, we understand the unique challenges that come with keeping cool in a Tucson desert climate.

Checking Your Air Filter

One easy way to get your air conditioner ready for hot weather is by keeping the air filter clean. That filter does more than you might realize. Its main job is to trap dust, dirt, and other particles before they reach the inner parts of your system. When it gets clogged, airflow drops. That lack of airflow makes the entire system work harder than it should. During hot months, the AC runs longer and more frequently, which can only make the problem worse. A clogged filter forces your unit to strain to pull air through, putting more pressure on the fan motor and other components. Checking the filter regularly and swapping it out when it looks dirty helps your air conditioner do its job without burning itself out. For some homes, especially those with pets or dust-prone areas, a monthly check makes sense. If you have allergies or asthma, it’s even more important to keep that filter clean. It affects both the air quality in your home and how hard your AC has to work. When you use your air conditioner almost daily, a dirty filter has a bigger impact on your comfort and your bills. A clean filter lets air flow properly, letting your system cool your home as intended.

Keeping the Coils Clean

Air conditioning systems rely on two sets of coils to keep your home cool. The evaporator coil handles the indoor air while the condenser coil releases heat outside. When dirt or debris collects on either one, heat exchange doesn’t work as well. The result is less cooling power and more strain on your system. Outdoor units tend to gather dirt, grass clippings, and even leaves throughout the year. Clearing that debris and giving the coils a quick clean helps air move the way it’s supposed to. Inside, the evaporator coil can develop a layer of dust or even mold if it’s not cleaned periodically. When air can’t move freely across the coil, it affects how well your system cools the house. Dirty coils make your air conditioner work harder to produce the same level of cooling. That extra effort shows up on your energy bill and shortens the life of your unit. Cleaning the coils before extreme heat hits helps your system operate more efficiently. It also gives you a chance to spot signs of wear or damage that could lead to trouble later on.

Checking the Thermostat’s Performance

Your thermostat tells your air conditioner when to run, so it needs to work right. If it reads the temperature wrong, your system might run too much or stop and start too often. That wastes energy and makes your home less comfortable. Newer thermostats let you set cooling schedules that fit your routine. You can cool the house more during the day if someone’s home or turn it down when it’s empty. Those settings work best when your thermostat reads the temperature correctly. Calibrating the thermostat or upgrading to a model with better sensitivity makes a difference in how efficiently your air conditioner runs. Testing the unit before the weather becomes extreme gives you a chance to catch any problems. If the screen reads 75 degrees but the room feels much warmer, something’s not right. Taking care of it now makes the rest of the season more comfortable.

Maintaining the Ductwork

Your ducts do a lot of the heavy lifting when it comes to keeping your place cool. If they’re leaking or packed with dust, air doesn’t move like it should. That poor airflow makes your system work harder than it needs to, which means higher bills and more stress on your AC. Leaks can occur anywhere along the ductwork, especially in joints or areas where pieces connect. When cool air escapes before it reaches the intended rooms, your AC has to keep running to make up the difference. Sometimes, the only clue you get comes from higher bills or hot spots that never seem to cool down.

Timing Your Maintenance Visits

When it comes to air conditioning maintenance, timing matters; the best time to schedule a tune-up falls in the spring, before the heat arrives. Early maintenance allows your system to handle warmer weather without straining from neglected issues. It also means you’re not competing with everyone else trying to book service during the hottest months. A pro can give your AC a good once-over — cleaning the coils, checking refrigerant, testing the thermostat, and making sure nothing’s worn-out or busted. It’s all about spotting small problems before they turn into headaches. Plus, it helps your system run smoother so you can count on it to keep things cool. Waiting until the heat hits makes things harder for both you and your air conditioner. When everyone’s trying to get their systems serviced, appointment slots fill up fast. Is it worth it to get yearly tune-ups? Yes. Make sure you get maintenance service done at least once per year. Even if your air conditioner appears to run fine, it may have hidden issues you're not aware of until they make themselves known. Having annual maintenance done can catch any issues that exist and get them handled so they don't compromise your system.

Understanding How Heat Affects Your AC

Scorching temps really push your AC to the limit. The fan has to work extra hard to get heat out of your house when it's really hot outside. The hotter it gets, the more your system has to work to keep things cool. Parts like the compressor and fan motors can wear down faster when exposed to high heat for extended periods. The longer your air conditioner runs without a break, the more likely it is to develop issues. Regular maintenance helps reduce the strain, but understanding how heat affects your unit makes a difference, too. You can help your system out by using ceiling fans to circulate air or shading the outdoor unit to keep it cooler. Putting the thermostat up even a little more during peak heat hours also reduces strain. Taking steps to reduce heat buildup inside your home goes a long way toward helping your AC run more efficiently.
