Arizona summers are tough on HVAC systems. After weeks of triple-digit temperatures, your air conditioner has likely been running almost nonstop to keep your home comfortable.
If you haven’t looked at your system in a while, now is a great time. A little preventative maintenance can improve efficiency, reduce the risk of unexpected breakdowns, and help keep your home comfortable through the hottest part of the year.
If you’re looking for a trusted HVAC company in Scottsdale, here are three things every homeowner should check before summer is over.
1. Start With Your Air Filter
One of the biggest causes of summertime service calls we see is restricted airflow caused by dirty air filters.
When airflow becomes restricted, your system has to work much harder to cool your home. In many cases, dirty filters can cause evaporator coils to freeze, reducing airflow even further and preventing your AC from reaching the temperature you’ve set on your thermostat.
Our recommendation is simple: check your air filter every month. A good rule of thumb is, when you pay your mortgage or rent, check your filter. Depending on your home, pets, and Scottsdale’s dusty environment, replacing it every one to three months can help prevent unnecessary service calls.
2. Make Sure Your HVAC System Is Running Efficiently
After running through weeks of Arizona heat, your HVAC system deserves a little attention.
A professional maintenance visit includes inspecting electrical connections, checking refrigerant levels, cleaning coils, testing system performance, and making sure your equipment is operating as efficiently as possible.
According to the U.S. Department of Energy, routine maintenance helps improve efficiency and can reduce unnecessary wear on your heating and cooling system.
Catching small problems now can often prevent larger, more expensive repairs later, especially during the hottest part of the summer.
3. Don’t Wait Until Your System Stops Working
One of the biggest mistakes homeowners make is waiting until their air conditioner completely stops working before calling for service.
If you’ve noticed weak airflow, uneven temperatures, unusual noises, longer run times, or higher-than-normal energy bills, your system is already telling you something isn’t right.
Having your system inspected before it completely fails can often prevent a small repair from becoming a much larger one—and help you avoid being without air conditioning during Arizona’s hottest days.
