Why Routine AC Filter Changes Matter in Concord’s Summer Heat

Summertime in Concord, California, can pose quite a challenge for your home’s AC. One of the best things you can do to ensure reliable cooling and prevent damage to it is to regularly change your filter. 


In general, you should keep up with AC filter replacement in Concord, CA, every month to protect against excessive wear, restricted airflow, and poor indoor air quality, as well as to enjoy the following benefits:


Maximized Cooling Performance

You don’t want to find yourself without reliable cooling during Concord’s notoriously hot summers. But if you let your AC filter accumulate too much dust, it can restrict airflow and impact cooling, and your system may not be able to maintain consistently cool temperatures when you need them most.


Improved Energy Efficiency

With a dirty air filter, your AC has to work harder to maintain its cooling potential. That means increased energy use, leading to higher AC bills each month. You can ensure optimal efficiency by changing your AC filter regularly, and the cost savings thanks to that improved efficiency can add up over the years.


Extended System Lifespan

As your system works harder to keep up, all of its parts will experience more wear and tear. That can lead to higher repair costs, breakdowns, and even the need to replace your system sooner than expected. Regular AC filter changes will keep your system running for far longer.


Greater Indoor Air Quality

Your AC filter also plays a key role in maintaining your home’s indoor air quality by keeping dust, pollen, and allergens from circulating throughout. It becomes less effective as contaminants build up, though, which can diminish your indoor air quality and bring about a slew of uncomfortable symptoms. You can breathe easier by keeping up with routine filter changes.


Comprehensive Tune-Ups and AC Filter Replacement in Concord, CA

Replacing your AC filter every month (or at least checking it for dust accumulation) will help you make the most of your AC system, but that’s not all there is to AC maintenance. In addition to AC filter replacement in Concord, CA, you should also schedule an annual AC tune-up with Mercury Heating & Air for maximum performance.
