"Had my spring maintenance done and couldn’t be happier with the service. The technician was on time, professional, and took the time to explain everything clearly they also swapped out my nest thermostat for an ecobee and got it set up. Everything is running great and I highly recommend Pass One Hour."

"Professional, courteous, very nice staff, always pleasant to deal with, and did their job Johnny on the spot!"

"B and D is very professional in all aspects of the work. Always on time, precise in his work, treats the job like he was working on his own home, has a great play list on his radio, and ALWAYS leaves the work site clean and neat. He even used a blower to clean off the front porch every night whether he worked on it or not. I have no reservations in recommending B and D for all aspects of your job. High quality!"

"Very professional and competent service at a very reasonable price. I will certainly use them for any HVAV work needed."

"Brandon is exceptional! He does high quality work and is very thorough. Even did some troubleshooting for another problem we had. He will go the extra mile for you. Great guy and you definitely won t go wrong hiring them"

"Vinc and his crew at VMK did and excellent job and I highly recommend there services ! Dave Caputo"

Just a detail oriented, clean freak with a bit of OCD when it comes to what I consider “clean”. I’m known for that! I can do a good job and I’m quick at that! Servicing most of southern Illinois, keeping our houses clean!!

"Shane and his team do really great work. Anytime I have a heating and cooling job I will definitely be calling them again. Thank you so much for replacing my ductwork."

"We had worked with another HVAC contractor for several years. While there service was good, their prices continued to climb and their responsivness declines. I was referred Clay by a friend of mine, whom had used him previously. Not only was he incredibly responsive, he gave me several options, told us his opinion on each and then let us decide what we wanted to do. There was zero pressure. We hired Clay and he and his crew not only did a great job, they cleaned up after themselves each and everyday, which my wife really appreciated!"

"They are excellent. I am a truck driver and not home very much. I needed my pipes winterized so they wouldn't freeze. The antifreeze is non-toxic. They drained my hot water heaters, put the antifreeze in. He turned off the water and made sure that it was winterized. I could turn the heat off. I thought it was high until, I realized they used two cases of antifreeze, and it is expensive. They were professional, courteous, and no issues. The price was good. I have no complaints with anything they did. I had to make an appointment, because they are busy. It took a while for them to come out on time and they showed up on time. Everything was good. They provided a good quality service at a reasonable price."
