Prime Time replaced our AC this past week, and we're feeling so good with our decision to hire…read morethem. They installed a water heater for us years ago, and this is still a great co to hire. First off, setting up an appt to get a quote was so easy over text. The office mgr is professional, responsive, and always polite. What I especially liked is how Kevin, the owner, double checked whether the old unit could be repaired, provided two quotes (standard and high efficiency), and installed the new Bryant unit. There is no separate sales and installation teams. It was clean, eventless, and done in 4 hours. Another co, recommended by ConsEnergy, gave a quote that was more for a standard unit. The second, smaller 22-year-old AC died the next day!! And what was really amazing is how they sent over Josh within an hour of my text to diagnose and fix that one!! Seriously stellar service. I highly recommend.

Matt, a Kotz supervisor in the Waterford office called her and said, "I will tell you what, you are just a very difficult person to deal with... you hear me? You are just going to have to call another goddamn company to deal with! I am done dealing with you! You are complicated and difficult and nobody wants to come out to your house and deal with it. You don't have any options! There's no one here that wants to take your work! Is this how Kotz treats disabled seniors after they get their home? Overpriced, by the way. Also, did not cap the chimney properly when installing a 96% efficiency furnace and now it is leaking. They won't address it, it was easier to kick this old lady to the curb!

We were introduced to Air Repair and Greg Drakewater at one of our monthly Real Estate Meetings…read more As several attendees currently use this company for their rental property HVAC systems and have been happy with their services and pricing, we decided to give them a try for our rental properties. On one of our rentals the tenant had called an HVAC company on their own instead of going through maintenance with our property manager. It seems that they were experiencing a problem with the furnace (it was winter when this occurred) and they were told it needed a new control board and the total was almost $1,000! We had our property management company inform them they should call maintenance for such problems. Then they scheduled Air Repair to check the furnace and they made a minor adjustment and charged me approximately $100. My general impression of Air Repair is that they are competent, honest, and reasonable and fair in pricing. They have since done AC repair on another property and continue to live up to their reputation.

He put down mats throughout so he would not mess up our floors. He was courteous and did a very professional-looking installation. I would have no problem recommending this company to my friends.

I purchased a Trane furnace and air conditioning system from Trzos many many years ago (like maybe…read more15-18 years ago). Both are still running with zero issues. This summer I decided to clean the air conditioning unit myself. A little tricky taking it apart. Even more tricky putting it back together. I called Trane for guidance, they told me to call my local Trane dealer, which I did. When I explained my issue, they put me through to Phil Trzos who spent the better part of 45 minutes discussing how to proceed with the self maintenance, complete with texting photos for his review and comment. 100% best HVAC customer service I have ever experienced. Phil made nothing but was kind enough to guide me through completion of my job. Thank you Phil! I'll be back when I need a replacement unit! Greg Woelfel Commerce Township, MI

Run, don't walk away from this company. Was a current customer with 6 year old furnace (and air…read moreconditioner) that they had installed. Had them out to check the humidifiers on both of my furnaces. 1) First unit needed small adjustment Second unit needed new solenoid valve not in truck Charge: $160 2) Return service call to install part, no itemized invoice Charge: $205 Researched the cost of exact part (he left me the faulty one) $20.77 on Amazon When I call and asked for an itemized invoice, I was told they didn't reveal what they charged for parts. Was offered a $25 discount. Ridiculous hourly charge for the second service call since they had already diagnosed the problem and only had to install a $21 part = $184 service charge This response on top of the fact that they know I'll need a new furnace and air conditioner in 2025. Will NOT be using them again Plenty of reputable companies in the area to chose from.
