Whats a MERV?

In the HVAC world, A MERV is the Minimum Efficiency Reporting Value. But what does it actually mean? A MERV rating relates to the filter in your heating & air conditioning system and its efficacy in air quality control. MERV ratings are on a scale of 1-20, and the higher the number means the fewer the contaminants that can pass through the filter. The MERV scale was designed by the American Society of Heating, and Air Conditioning Engineers (ASHRAE) to represent filter’s performance at removing or blocking particles from .3 to 10 microns in size.

A micron (or micrometer) is a unit of measurement approximately one millionth of a meter. To give perspective, wool fibers are considered to be usable for garments and carpets at 25 microns. So yeah, .03-10 is pretty small!

So what does that mean for you?  If you have a air conditioning & heating system in San Diego, the filter is incredibly important in removing particles such as pollen, dust mites, carpet fibers, mold spores, dust, pet dander, bacteria and airborne contaminants. Residential systems will typically remove these airborne contaminants with a MERV rated filter 7-12. MERV ratings of 13 and higher are usually found in hospitals, surgical settings and in even higher ratings clean rooms.

download (1)At Bill Howe heating & air conditioning, all standard filters installed have a MERV rating of 8. We also advise homeowners to regularly clean air ducts to remove impurities from the air and perform a maintenance on their heating and air conditioning system annually (twice a year if you have A/C and heat) in San Diego.

Heating & air conditioning tune-ups include changing out old filters and will extend the life of your HVAC system. To schedule your pre-season heating tune-up in San Diego, call 1-800 Bill Howe (245-5469) today! You’ll be glad you did!

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.
