Michigan summers reward systems that are sized for humidity and airflow—not just a bigger condenser in the yard. We install and service central air for homeowners across Genesee County and surrounding communities—including Brighton, Howell, Hartland, Byron, Flint, Durand, Flushing, Holly, Davison, and nearby towns—with careful charging, drain testing, and thermostat integration on every job.
When something breaks, we test pressures, temperatures, and electrical components so we fix the underlying issue, not just the first symptom. Safety and warranty protection matter on refrigerant and compressor work—we do it by the book.
Cooling installs and dependable repairs
Homeowners across Genesee County and surrounding communities choose a team that plans line sets, electrical, and airflow carefully on new installs—and that stocks common parts and communicates clearly when you need cooling back fast.
Professional installation
— load-appropriate equipment, safe refrigerant handling on replacements, and startup checks for charge, airflow, and controls.
Lasting repairs
— systematic diagnosis of coils, refrigerant, capacitors, contactors, and drains so the same symptom does not return next week.
Seasonal tune-ups
— spring maintenance helps efficiency and catches small issues before peak summer demand.

What our customers say about our cooling work
I have used Machlin heating and cooling in the past when I had issues with my air conditioning they were very responsive, thankfully they were able to get me up and running the same day. Recently my Bryant furnace stop running almost a 30 year old unit. Temps were in the 20’s and I was in need of a new furnace. After going through all my options I decided to get a new furnace and air conditioning unit with Machlin heating and cooling they did a very good job of explaining, very clean, professional and in great detail what they would do, they had multiple options for financing. I highly recommend Machlin heating and cooling for maintenance repair or a new unit.

Another red-letter day in The Wurlitzerage! Two mini-split (heating and air conditioning) units were mounted on the newly-constructed interior side wall, and connected to the heat pump, which was set on the recently-poured concrete pad behind the building. I can’t say enough good things about Macklin Heating and Cooling!! Not only did they show up precisely on time after unparalleled advance communication, the did a superb installation job, AND sent me a treat shortly after completing their work. HIGHLY RECOMMENDED!

Before today, I had never had Air duct and vent cleaning completed in my home. There are many businesses in the area who provide this work. Looking online, Mackin Heating & Cooling was my first call, and I didn’t have to call anyone else! They were responsive and prompt. Mike went through all of the duct areas on the house with me, explaining all that would be done, and then provided a quote. He was knowledgeable, friendly and answered all of my questions. He came back to do the work a few days later. On the day of, Mike again explained everything that would be done. Afterwords, he also provided me online before and after photos of the results. I am so glad I to have chosen Mackin Heating & Cooling and I HIGHLY recommend them!

I cannot thank Wayne and his son for an amazing HVAC replacement experience. Besides the purchase of my new home 3 years ago, this was the biggest financial investment I have every made. I was nervous and Wayne and his team made me feel extremely at ease. Installation was not as long as expected; couteous and careful. Wayne initially took the time to connect with me, help me understand what type of system I have and all of my options. No pressure to purchase and that made me feel all the more at ease. I was able to initially make a deposit and did not have to pay balance until I was 100% satisfied. I 100% recommend Macklin Heating and Cooling to service all of your HVAC needs. Give them a call.

From start to finish this company (and all who work here) are professional, extremely knowledgeable, and friendly. It’s rare to get one on one with a knowledgeable expert who explains everything to you in detail and answers questions without making you feel pressured or rushed. This company is a family-owned business and they definitely make you feel like part of their family. Prices for a new air conditioning unit for our home were very reasonable and I dare anyone to try and beat their warranties! Thanks to Mike and Wayne and everyone at Macklin for getting us up and running with a brand new Bryant unit. Top quality all around!

Central A/C installs and field service—condensers, line sets, and indoor equipment done to a professional standard.
Frequently asked A/C questions
How do I decide between repairing or replacing my air conditioner?
We weigh age, refrigerant type, repair history, efficiency, and repair cost against replacement value. If a repair restores several seasons of reliable cooling at fair cost, we recommend it. If not, we help you compare new equipment calmly.
How long does central A/C installation take?
Many replacements finish in about a day. Scope grows if the panel, ductwork, or line set needs major changes—we outline timing before we start.
What are signs I should call for A/C repair?
Weak cooling at registers, ice on the line set, water inside from a backed-up drain, odd sounds, or a sudden jump in electric bills can all warrant a professional visit. Refrigerant and high-voltage work should be left to licensed technicians.
