How to Know if You Need Your Air Ducts Cleaned

When not properly installed, maintained and operated, components of your heating and cooling system may become contaminated with particles of dust, pollen or other debris. Some of these components include supply and return air ducts and registers, heat exchangers heating and cooling coils, and condensate drain pans (drip pans).

When is it necessary to get an air duct cleaning:

  • Upon inspection of the ducts, the registers have excessive amounts of dust, debris/particles and pet dander
  • Ducts infested with pests (rodents, insects, etc.)
  • To improve efficiency of your heating and air conditioning unit – air duct cleaning alone will not improve the efficiency of your unit, but should be done as you perform regular maintenance which should include a tune-up and filter change
  • Mold Growth: you can request a video inspection of the ducts to show you the mold. Be aware that although a substance may look like mold, it should be confirmed by an expert and may require laboratory analysis for final confirmation

Things to consider when hiring a company for air duct cleaning:

  • Do not allow the use of chemical treatments or biocides unless you fully understand the pros and cons
  • Check references: ask to speak with satisfied customers to ensure they didn’t experience any problems with their HVAC system after the duct cleaning
  • Contact the San Diego Better Business Bureau to check the company’s rating and any existing or previous complaints regarding their business practices
  • Charges: if the company charges by the hour, request an estimate on the number of hours or days the job will take

Bill Howe Heating & Air Conditioning is a leader in San Diego air duct cleaning. We recommend cleaning your air ducts every 2 to 3 years or as you see needed using our recommendations above, changing your air filter twice a year, and scheduling an HVAC unit tune-up once a year. The air duct cleaning process takes, on average, 2-4 hours and consists of using a combination of an air scrubbing brush and HEPA filtered vacuum. HEPA (high efficiency particulate air) is a type of filter that can trap a large amount of very small particles that other vacuum cleaners would recirculate back into the air of your home.

It is normal for the return registers to get dusty as dust-laden air is pulled through the grate. This does not indicate that your air ducts are contaminated with heavy deposits of dust or debris; the registers can be easily vacuumed or removed and cleaned. In order to best determine if you need an air duct cleaning is to have a camera inspection of your air ducts.

At Bill Howe Heating & Air Conditioning we want to make sure you have the most efficient running HVAC unit without enduring extra stress on your budget. While it’s important to take the necessary steps to make sure your heating and cooling system is ready for the next heat wave or cool season, we want to make sure you are aware of your options. Want to find out if you’re in need of an air duct cleaning or tune-up? Call us, because We Know Howe.

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.
