Air Conditioning Contractors Muskegon MI

How to pick a good A/C contractor.

Hi let me introduce myself.

I'm Mark Grant. I am a licensed Mechanical contractor. Owner of MR HEAT & COOL. Muskegon, MI


I have category 1 Hydronic Heating / cooling and process piping. 2 HVAC equipment 3 Duct work 5 Limited Heating Service up to 400,000 btu on a single piece of equipment 7 Limited Refrigeration and AC Service up to 40 Tons and A Solar Specialty.

I also have a boiler license b1 installer which is for commercial boilers up to 1million btus and residential boilers over 400,000 to 1 million.


This, I point out to let the home owner and business owner know there is more to the license than just one category and it helps discern the experience level of the contractor and whether he is qualified by the State of Michigan to do what he is proposing with the correct credentials.

If a contractor only has HVAC equipment they are not legally qualified to service HVAC equipment. They must have one of the service categories which proves they worked in service.


Many unlicensed or non service licensed individuals do service when they are not legally qualified and this could leave the home/building owner on the hook for damages caused by them when it leaves a loophole for their insurance company.


Make sure your contractor is insured, licensed in the category in which he is working and they pull a permit per Michigan code in order to assure your insurance coverage holds up.

If you are having any alterations or installation/replacements done chances are a permit is required. If and when you go to sell it is becoming an important point as well.

Another good point is to look for an ACCA contractor. Those who care enough to be a part of an association which looks out for the integrity of the industry and health and safety the way Air Conditioning Contractor of America does is a quality company. I have been on the board of directors for Michigan Chapter and President in 2009 and 2010 as well as the West MI Chapter of ACCA.

I have over 21 years experience in Muskegon. I am also a US Navy Veteran.


I am passionate about the job I do and treat every job as if I were doing it for my Grandmother.

Feel free to call me with any questions regarding code or installations. I take pride in diagnosing problems with systems and getting to the bottom of long lived problems others couldn't seem to fix.
