FAQs About AC Maintenance

Big Mountain Heating & Air wants all of our customers to be as informed as possible about the importance of AC maintenance. We encourage you to ask questions and learn more about your AC system because not all maintenance is done by the technicians on our team. The more you know, the more capable you’ll feel when determining how well your unit is running and if you need a repair or replacement in the future.

Our experienced technicians hear many questions from homeowners about their AC systems, and we want you to know you’re not alone! We welcome any and all questions about your AC system and have complied some of the most commonly asked AC Maintenance and Filter questions for your Sacramento AC system.

Common AC Maintenance Questions

What Are Some Maintenance Tips for Homes With Pets?

If you have extra furry members of your family you may have noticed that they tend to release a good amount of hair, fur, and dander. These contaminants are okay to inhale naturally, but in large amounts, they can be harmful to both your lungs and your AC system.

Hair and fur tend to clog the air filters in your cooling system very quickly. Some of the things you can do to be extra vigilant are checking/cleaning your air filters more often and vacuuming more often. Dander and fur tend to cling to floor coverings like carpets, so it’s a great idea to clean them regularly to avoid the constant presence of hair and fur in the air.

How Often Should AC Coils Be Cleaned?

AC coil cleaning is one of the important tasks that certified technicians complete during AC tune-ups. We recommend your AC coils be cleaned once a year during your AC rejuvenation. Many things – including clogged air filters – can cause your coils to become dirty or even freeze. The coils are an important part of the chilling process, which can’t occur if they’re out of order. If your coils do freeze up throughout the year, our team of technicians can quickly repair it.

Do Split-System ACs Need to be Serviced?

Even split-system ACs need annual maintenance. These systems have two separate units – the outdoor and indoor units – that connect through pipes and tubes. The outdoor unit needs to be checked for mechanical function of the compressor, coils, and more.

The indoor unit must be checked to ensure the filters are clean and that it is delivering air successfully to your home. The connections between the two units must also be checked to ensure there are no leaks.

Air Filter Questions

Even though your annual tune-up includes an air filter inspection and cleaning, you should be checking your air filters several times a year to ensure they are clean and working properly. If you’re not sure how to complete this task, the following are some of the most common questions specifically asked about air filters.

How Do I Clean My AC Filter?

It all depends on the type of filter your AC has. Some can be removed and cleaned with soap and water. After they are cleansed of dust and dirt, they must be allowed to dry completely before replacing them. Damp air filters could cause mold to grow which is very dangerous for your health. Other air filters can be thrown away and replaced with brand new filters every few months.

Is There a Wrong Way to Put in an Air Filter?

Yes, you can make the mistake of installing the air filter backwards! Most air filters have arrows printed on them that are all pointing the same direction. Follow those arrows to place the air filter back in its place the right way. A backwards air filter is not the end of the world, but it does prevent the air system from flowing correctly and can even put stress on your AC system if the air cannot easily flow.

What Happens if You Don’t Clean the Air Filter?

Failing to clean your AC air filters regularly will cause a number of symptoms in your home. First, your AC will struggle to push air through clogged filters and most likely use more energy to do the same job. Second, with enough time any air contaminant can collect with the dust and dirt stuck in the filter. Pollutants like mold or bacteria could cause problems in the future. Third, your indoor air quality will absolutely suffer if the filtration system is backed up and unable to perform. You may notice more allergy symptoms or even respiratory distress from those who are sensitive to airborne pollutants.

What Our Customers Have To Say

Good Rebates

This is a review for a complete HVAC system replacement from Big Mountain. I started at the SMUD website looking for the best rebate program and found a list of contractors there. I vetted out companies that had a lower number of completed jobs per the SMUD rebate program data.

Very Professional

Had my A/C go out yesterday, called Big Mountain today and they had a serviceman in my area of Lincoln, he was here within a half hour and fix my unit in a very professional manner, and the cost was reasonable. I was very impressed with the company and the serviceman.

I had a appointment with them between 1-3 and one of their staff members called me and kept me updated when they will arrive which was nice. Steve arrived on time and was really nice for explaining what could the cause be. My ac fan was working but cool air wasn’t coming out.
