Why you should keep your HVAC air filters clean!

The heat wave may be behind us, but that doesn’t mean we should forget about maintaining our HVAC units! When it comes to HVAC, San Diego residents can count on Bill Howe Heating & Air. After all, we know that to keep your HVAC system running well, it is important to follow these two simple steps. Replace your indoor air filters regularly and have a San Diego HVAC specialist give your system a tune-up once a year.  It’s never too early to get ready for the cold weather, you can get your heating tune-up now and make sure your heating unit is ready the minute you need it!

However, if you suspect you already have an issue, don’t worry because we can help! At Bill Howe, our technicians often find that filters with excess buildup have created problems for our customers.  A clogged filter stops airflow and puts more stress on your system. This drives up utility costs as owners attempt to correct poor air quality by running the AC or heat more often. Air slow-down can result in iced-up evaporator coils or cause the system to overheat. These problems can lead to HVAC failure or, in the case of over-heating, can spark a fire. Fortunately you can prevent these problems by calling one of our expert San Diego HVAC technicians for a tune-up.

If these filters aren’t replaced and the unit is not regularly inspected (we recommend twice a year), the system will reduce the heat-exchange rate. A lower heat-exchange rate will cause the system to fail over time. Then, the evaporator and condenser may break down as a result. Tune-ups by a professional technician will clean out debris and allow the system to function effectively.

Additionally, dirty filters result in lower air quality, which can lead to various problems. Poor air quality has been known to inflame allergies and cause other health and respiratory issues.

So, a good rule of thumb is to change air filters in the house every month and to have an HVAC tune-up once a year. If your business creates a high dust environment, it may need multiple tune-ups during the year. Additionally, homes with pets may need a tune-up more often if filters are easily clogged.

We are the preferred local company when it comes to HVAC. San Diego home and business owners have trusted us for years, and you can too.

What David says about us

Service for new garbage disposal. My ancient garbage disposal quit working, went online to get Bill Howe’s number, immediately received and accepted chat to describe my needs. Prompt call back to schedule an appointment, service tech Allen was out same morning, which was important to fit my work schedule. Job estimate was clear, work done fully to my expectations, area left clean, and price was very fair.
I was not surprised — I have used Bill Howe plumbers for several other tasks in the past. I have always found their staff to be helpful, attentive, and the plumbers very courteous and capable.

What Mira says about us

Bill Howe never fails us! We had a drain overflow, and Scott came (on a Saturday) to look at it and offer solution. He was punctual, professional, and extremely helpful. I should also praise the main office for always being helpful and always finding solutions. Very grateful to have you in San Diego!

Cory was our technician on this job. We had a time sensitive repair issue and Bill Howe understood and assisted with getting the job done quickly.
Cory was on time to start the job and finished it quickly. Upon his leaving our home he’s was courteous, very knowledgeable, explaining what the problem was and how he fixed it. Very good communication and this is the way it’s has always been when we use Bill Howe plumbing.
Great company to work with.
Thanks Cory.

What Bridgett says about us

I am extremely happy with the service we received from Bill Howe Plumbing. We were given an incorrect diagnosis of our main sewer line from another vendor, but Bill Howe’s servicemen came out for a second opinion, correctly diagnosed our problem and resolved our back up issues. We will continue to use Bill Howe for all our future plumbing needs!

Thank you Bill Howe Plumbing.
