"Design and Sales Consultant Scott M. was great, both during the sales process and in-person at the home on installation day to ensure all went well. Even after the sale he followed up on a few questions and went above and beyond. The installation team, Joe & Joe, did a terrific job correcting an awkward install another company did in the past as well as installing the new equipment with great care and attention to detail. I highly recommend Lozier!"

"Ryan and Joe from Lozier did an absolutely wonderful job. Both went above and beyond to get the job done right. Ryan laid out the cost and benefits perfectly and didn't try to over sell me. He made sure I knew what I was paying for and understood that I was in a budget. Joe worked hard to fix issues he found in the AC that a different company installed 2 years earlier when he was technically only there to replace the heater. Lozier made sure that when they left everything was perfect and working correctly, whether they installed it originally or not. I don't leave many reviews online but Lozier earned my time to write this one."

"Very knowledge and professional. From the time I called to schedule the appointment to the time the HVAC tech left was approximately an hour and my furnace was running properly again. It was a very good experience and I highly recommend them."

"Our furnace went out at 9pm on Christmas Eve. We called the company that had serviced it for us in the past. They told us someone would be in contact, but by 1 am they hadn’t called. I called Lozier, and we had a tech in our house within the hour. He was extremely helpful, explained everything, and our two kids didn’t freeze to death in the night. I couldn’t recommend them more highly."

"We have been using Lozier's since we moved to DSM in 1990. Today was our service/tune up and Shawn was thorough and efficient. In checking the AC unit, he noticed that it was not working to capacity. I made the decision to replace the part now rather than to have an emergency call later this summer. I appreciate the reliability and professional service that Lozier provides."

"Loziers is the only place we trust for our heating and cooling needs. They are prompt, friendly, fair and their technicians really know their business. We have always gotten top notch service from Loziers. We had Larry out this morning for our air conditioner tune up and he did a terrific job! Also we have had Rick out for our water heater and furnace tune up and for some repairs and he also did a terrific job for us! I recommend Loziers to all our family and friends.."

"10 years ago we got a new HVAC system from Loziers. We sign up for the yearly maintenance plan, which insures a system check each spring and fall. All technicians have been prompt, clean and polite. Larry, who serviced our unit before, was here today. As usual, very polite, prompt and knowledgeable, answered all questions and left me feeling comfortable and reassured that our system is working properly."
