Heating & Air Conditioning / HVAC near East Troy

“The staff is always friendly and thorough! Our furnace and air conditioning quit working over the weekend. When James Bonyata came out today, he explained everything he needed to do. When he found the problem, he gave us an estimate which we approved. When he was all done, he thoroughly explained what he did and make sure we understood our system! Once again, great work and reasonable prices!“

“Jeremy did amazing work! He was expedition and got my new air conditioning unit installed just before the 90 degree heat….thank you again! I’ll definitely use him in the future!!“

“They did great work and were very punctual with their diagnosis and repairs. Highly recommend!“

“One of my vacation rental homes had a slow leak that had to be taken care of before a guest checked in that day at 4pm. I called Adam's and had immediate service!“

“Outstanding Service! Our AC unit needed repair and I contacted Brenda at Martens for service.. She had their office call me and they were here the next morning.. Ryan was professional, competent and had us up and running in short time .. Thanks again..“

“We operate a short term rental home and our furnace went down on a Saturday night which was also part of a holiday weekend. I had not used Westenn before and wondered if any emergency service repair companies would be answering during the holidays. My call was promptly answered and a service person was on his way. He even had the part we needed on the truck. We were up and running within an hour. Our property manager also commented that it was the fastest response she had ever seen. Westenn will be our new service provider and I can't thank them enough for the great after hours service and especially during a holiday weekend. Last but not least, the pricing was fantastic and so fair especially because it was a holiday weekend!“

“Personalized, expert Master Plumber Service, at a fair price. I had a toilet leak. He diagnosed the problem, which was different than what I thought. He fixed that toilet and checked out our other two and replaced the parts on those as well. All in the same trip. I received excellent, personal service all around, from the first phone call all the way through to paying for a job well done. Honest, Efficient work, at a fair price.“

“Our company uses A to Z to do periodic maintenance and repair service on our Follet Ice Machine. Over several years the service has been very good and reliable.“

“Holy cow, 10/10 for thoughtful and responsive customer service that I just haven't seen from trade service in a while. The work isn't even done, and I am so thankful for their time, efforts, and insights. We had been struggling for quite a long time to fix our jetted tub, and we finally found solace. Just — SO thankful.“

“I dealt with David to install a garage heater. Great communication and follow up. I've used them for another project as well and have always found their prices competitive and their service top notch. Will do business with them again.“

“Have worked with Square 1 for years. They never let me down. Recently thinking of updating my HVAC, Kyle came out and made a pre-emptive suggestion to replace the hot water heater immediately. He was right, it was about to burst! Anthony and Aiden were terrific installers, left the area completely clean, and were on time in delivery and installation. Great company, high quality employees!!“

“This was my 1st time calling about a thermostat problem. I spoke with the owner Mike who was really nice. The next morning he sent over his HVAC guy Chuck. He was polite, patient and answered all of my questions. I'll be calling you guys for all my future needs!“

“Very positive experience. AC condenser stopped functioning. Called for service and was greeted with efficient scheduling. Richard was able to diagnose and fix the problem (capacitor and coolant) quickly. Recommend highly for your HVAC needs.“
