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 Joel C says about us

Very Satisfied. Michael is always on time, Michael has been doing all of the plumbing related to our remodel. He always does exactly what he commits to do within the estimated cost. He keeps me informed if any wrinkles pop up, and his plumbing skills are excellent as we have had no problems or issues arise after he has left. Very professional! Highly recommend.

What Rick M says about us

We had other companies come out for estimates on what was considered a major job with jackhammers and replacing cast iron pipes under the house… having been stung before, we wanted another estimate just to make sure we were making an informed decision. The prior estimates went up to $21,000!
Bill Howe sent us an amazing veteran plumber, Dashawn and his co- worker Anthony. Dashawn did a thorough check of the problem, explained what he thought was needed … he did a final check and we were able to see for ourselves what was the problem. He recommended a complete cleaning to de-scale the pipes, and not the major work we dreaded. Thanks to his solid analysis and patience in making sure we saw what he saw, the issue was resolved completely, and saved us thousands of unnecessary work. None of the other estimates included the cleaning; only the major repairs. Thanks to Dashawn’s knowledge, professionalism and honesty, we’re Bill Howe customers.

What Carolyn Housman says about us

This was our second excellent experience with Bill Howe. We had a blocked kitchen sink drain 8/5. I was able to get a same day appointment which is AMAZING. Person on phone was very courteous and set me up right away. Tony arrived at the house (called me 30 minutes out so I was able to be ready). He diagnosed the issue (blocked drain, not the garbage compactor) and was able to snake it and ran the water for 10 minutes to be sure the drains were clear. He cleaned up everything and you would not have known he was even there. Thank-you Tony and Bill Howe, you always know how.

What Ed Gohlich says about us

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.
