Best Heating & Air Conditioning / HVAC In Kalamazoo

“Jacob came out on a Saturday when the furnace wouldn't fire up. He quickly diagnosed the problem and resolved it in about an hour. Excellent communication before and after the repair. Professional in all aspects.“

“Old folks who lived rural without air conditioning for over 36 years in this home, finally decided to try to find comfort after the hot, humid, wet Michigan summer of 2024. Two generations of our family have always relied on Bartholomew for heat/water issues. By summer of 2025, we went ahead and finalized the estimates/product/cost and schedule of a large split unit installation (1,500 Sq Ft house).
This company and product (Bryant split unit) made a hot, humid miserable summer 2025 100% bearable AND enjoyable. The surprise was that our electric bill only rose about $12 a month for the electric air conditioner system that stayed at 74 degrees and 50% humidity for over 7 weeks uninterrupted. We do not have a furnace (heat with wood)- I do not have curtains to insulate even more. But this whole thing was beyond efficient. This thing even lowered the humidity and temp in the basement level!
Thanks to techs Dan and Will from Bartholomew, and Jen in the main office (she gets 7 star review). Thanks also to their partnership with Lamplighter Electric- Craig and Nathan who pulled it all together! We do not have a regret in any aspect!

“I received a MI-HER (MI-HOME Efficiency Rebates) grant. Part of the process is choosing a MI-HER Certified Contractor to work with. I researched my area and found Better World Builders on that list. The reviews I read were incredible, so it was a pretty easy choice. It didn't take long for them to reach out to me to start the process. Nick explained the process step by step, and has kept me informed throughout. I've spoken with office staff, Roy-Production Manager, even Mark- the Owner. Every one of them has treated me with kindness and made me feel valued. They truly listen to every concern you have. If you have applied for this grant, choose BWB for your contractor. You won't be sorry.“

“Excellent mechanical & plumbing contractor to work with! Doug & his team gave a great proposal, did exactly what he said he would do, and THEN followed through perfectly! Very intelligent & professional= GREAT JOB!!“

“They were willing to come on short notice, between appointments, and on the first really cold day of the winter when our furnace igniter went out. They did a great job, charged a very fair price, and were very quick and professional. I had never used them for a repair before, only one other time to do a furnace check up when were first bought our home (2+ years ago)and had the same experience then. I am impressed and grateful for the quick response and repair. I highly recommend them based on my 2 experiences.“

“They were amazing. Quick. Honest. Affordable. Professional. I was very grateful for the service!“

“Had used DeHaan previously on a different home and decided to give them a try again. I was converting from a 120 gallon electric water heater to a Navien PE-240A2 - 199,000 BTU Indoor / Outdoor Advanced High Efficiency Condensing Tankless Water Heater and control panel.

There were 3 workers who arrived exactly when they said they would be there. Were polite and listened to what I was attempting to do as far as aesthetics. They began right away. There were a few areas that I asked for them to correct as I am a stickler for detail and they did not hesitate to fix it the way I wanted it so long as it met code. Install took about 6.5-7 hours to do, but everything worked great on first run. No leaks, and adjusted control panel, tested water temp and worked great. They cleaned up everything and hauled away my old tank.

Once again, would highly recommend DeHaan and Abe. They installed this at an extremely affordable rate compared to others.

I have attached before and after pics so you can see their workmanship.“

“Working with Matt was great! He is very professional in every way and he and his crew were great on a sewer connection at my home they did all they said they would do and more. If you are looking for a plumbing contractor you can not go wrong with preferred plumbing. Lee Wolfe“

“Metzgers replaced my old furnace & added a/c several years ago. Their routine service is excellent & they are very responsive in an emergency. Technicians are knowledgeable & pleasant.“

“Adams Heating & Cooling has done an annual furnace check up for us for years – – maybe that’s why our last furnace made it 21 years before dying. (“Try and repair it first, and save the customer some money,” as they say in their commercial.) When we needed a new furnace, there was no question where we would turn for our next one. The Adams installation team – – Mike and Dan – – were knowledgeable, efficient, considerate of our home, and cleaned up after they finished (Everyone says they will, but not everyone does.) We love that it is a family owned, local, small (but mighty and growing) business.“

“My wife and i were very pleased with the sales rep was very informative on the AC and gave us a very reasonable price and installers they were very respectful of our home and left no mess when done. I have had work done by you in the pass and was always treated with respect and fare deals

Thank you E.M. Sereant“

“These folks installed my HVAC in 2024 and did a great job at the time. Their service since then has also been top notch, with courteous staff, good scheduling, and an overall professional job. Would not hesitate to recommend.“

“Our church has moved all our business to Great Lakes. The office is professional, pricing fair, and the plumbers go the extra mile. Our church is very old, thus lots of difficult repairs. Every time, from small projects to large projects, things have been completed superbly. Go Great Lakes, Go!“
