"very impressed----joe the estimator was very knowledgeable and not pushy-----gary the installer was super and very careful to clean up every little bit of dirt---mike who did the furnace tune was super ------------how often do you have a company so honest that when you ask to have a 20 year old furnace checked out----they do a very detailed check and show the details and they don't try to ram all sorts of repairs at you--they actually said everything is fine for now ( guess who I'll call when I need one }--they were right on par with 2 other companies I called for estimates----awesome job"

"I had lost heat to my boiler late one night in February. With my family gathered around our fireplace in the living room & heat dropping on one of the coldest nights of the year, I was concerned. JB Mechanical responded first thing in the morning. The technician did a nice job of diagnosing the problem. After a few hours we had our boiler up in running. They also worked with me on the price, adjusting accordingly. A job well done by Patrick, the technician."

"Our nearly 40 year old boiler system had seen its last day. Steve with Guardian was easily accessible by phone, prompt, and helpful. He installed a new boiler and retooled the set up of our system. We re very happy with the service, speed of the install, and professionalism the guys showed. We didn t shop around much since we weren t interested in having too many people coming in and out of the house during the pandemic, but felt confident Steve was giving us good information and a fair price based on what we were told in the past and research we had done. I would certainly recommend Guardian to friends and family. I will update going forward if necessary since the system is currently a day old, but the house is as toasty as ever so mission accomplished thus far."

"This was the year my old klunker (furnace) decided to stop working. Great,just wonderful. So I picked up the phone and made a call to 1st Choice Heating. They had a technician dispatched faster than I expected. The news was not good,I needed a new furnace. I was quickly put on the schedule and my furnace was in before I knew it. Thanks 1st Choice team you were awesome from the first call to the install!!! "

"Great Job, Mike was able to get to the property same day and complete full installation within the day. Worked late hours to make sure it was complete and kept in great contact from initial inspection until installation. Will definitely use for any HVAC services moving forward"

"Jeff responded immediately to the initial call. My work hours are not flexible and I was delighted that Jeff was willing to visit the house that very night around 6 p.m. That night, he got the dryer working temporarily until the correct part could be obtained. Returned a few days later with the replacement part and completed installation. The invoice includes parts and labor only. No flat fee for the first visit, or additional fee for locating the uncommon replacement part."

"Tech was punctual and friendly. Diagnosed the issue with the switches and outlets. Replaced half of the switches and the outlet repairing the problem. Unfortunately the new switches and outlet did not match the previous color leaving me with 2 white switches and two almond switches in the same bank of switches. Tech told me they could not make them all match because they don’t carry almond color switches. Completed after work survey and was contacted by customer service who stated that they would have a tech come back to the house and install the new white switch that i had purchased due to the inconvenience. New switch was installed without issue."

"We called Midwest heating and cooling because our furnace was not turning on and heating and the day before when it was on the back of the unit was hot. They came out next day in a timely manner. Very polite and Friendly. Did a diagnostic look at and explained me what was wrong. Along with what he did to fix the issue. Our technician took lots of pictures as to how it looked when he started what his meters were saying with the numbers. Along with what it looked like when done. We got all of that emailed to us and is kept on file if they ever have to come out for something else so the same tech or another tech sees what was done the last time they came out. Our tech Ken explained what all the numbers ment on his picture so we understood things clearly. Told us about a membership program they offer to help out the customer and give them peace mind the next time you need something done. Ken was very knowledgeable and very kind. Would highly recommend."
