Total Home Comfort

Comfort for your Whole Home

HVAC problems don’t exist independently of other issues in your home. Similarly, your HVAC system can’t perform at its best without cooperation from your entire home and all of the other systems you operate every day.

M & M Heating and Air partners with the Comfort Institute to provide Whole House Comfort. Our contractors are trained to see the whole picture from the HVAC system you currently operate to the appropriate fit of the one you’ll buy next and from the air quality in your home (and how it impacts your family) to the energy bills you’re paying.


Why do we care about all of those other things? Well, to put it simply, it’s our job. Any HVAC contractor who overlooks any of these elements isn’t doing his or her job the way we would.


  • High Energy Bills? These high costs could also indicate a performance issue in your HVAC system or an air leak in your home we wouldn’t have found without considering your increase in bills.

  • Cold or hot zones in your home? We want you to experience WHOLE home comfort. This means that from the attic to the half-bath and back, your home should be heated and cooled evenly and reliably without worry. We’re here to help!

  • Comfort Institute Member
  • Air Quality Issues? If your air is too humid, too dry, or too contaminated, your asthma or allergies could flare, and you won’t be comfortable. At M & M, we care about your well-being AND the quality of the air you breathe. Again, air quality issues can also wreak havoc on your HVAC system and/or indicate that you need a repair.

Indoor Air Quality

Indoor Air Quality for Stockton Homeowners

Air Quality matters. This crucial part of home comfort is often overlooked by other HVAC contractors who are concerned with your thermostat and their bottom line – and that’s it! Our holistic approach to home comfort includes concern for the following air quality elements:

  • Humidity Index
  • Air Cleanliness & Contamination Prevention
  • Air Filtration
  • Carbon Monoxide Detection

For over 40 years, we have worked with homeowners and business owners to provide and service electronic air filters, duct zoning, ventilation systems, duct cleaning, and more. It’s as important to have your ventilation system and ducts cleaned periodically as it is to clean your carpets or dust your furniture. By overlooking this important maintenance item for your home, you put your family and yourself at risk.

&M Heating & Air Conditioning Service Co. is a certified member of the National Air Duct Cleaning Association, the organization that standardizes the way we clean your ducts and repair issues found. We offer FREE estimates for this service so you don’t have to decide for yourself – or pay us to decide for you – whether you’re due for a cleaning. We’ll let you know at NO cost to you! Easy, right?!
