Get matched with top heating oil pros in Pueblo, CO

"So helpful and knowledgeable!"

"I just have to say thank you to Clark's mechanical and Corey for the amazing job on my split mini heat/air. Our technician Cory was reliable and expert in his HVAC trade. He had a solution that didn't break the bank literally in five minutes. I'm mean honestly I called about a dozen places just asking them to take a. Look. They all wanted hundreds to merely dispatch a tech. Clarks Mechanical was Jonny on the spot. Just a few hours later we had heat and air conditioning at a reasonable price. So yes I wholeheartedly recommend Clarks mechanical every day and twice on Sunday"

"Save your time on 2nd opinions, this is your heating and cooling company! We had 4 different companies come out to give us a quote for our job and Julian quickly stood out as the best option! His prices were very competitive with the other companies that came by but what really sold us was the customer service! Julian came out on his day off just to walk through our home and give us a quote. He sat on the couch for an hour and answered all of my questions. Not once did he get frustrated or impatient. After we accepted his quote he was in there the very next day to start the work. All of the work was professionally done and completed that same day. We were out of town during his work but Julian communicated with us the whole time and sent us pictures of the work when he was done. He went above and beyond to make us feel very comfortable with our decision to put our trust in him. He and his team have added another lifetime customer to their quickly growing list. They also offer great financing options for large projects with interest rates far lower than any credit cards! Do yourself a favor and call them first!"

"BEWARE terrible company, was contracted for a furnace install, took 4 months to complete and three failed final inspection. The owner corey had very limited communication with no updates and only responded to about every 5th message. The is the horror story you worry about with contractors"

"6-24-25 I originally gave Trey, a technician from One Source Home Service in Colorado Springs. CO, a 5 but now that has gone to a 0 and here is why. Trey did provide a maintenance service on the AC on 6-16-25 and also a service to clean the blower on the furnace on 6-20-25. But after he left Friday, I went to turn on the AC since it was 101 hot in Pueblo, the AC motor did not come on so my AC was not working. I called and texted Trey. Please note that Saturday it was going to be 103 in Pueblo. Trey said he will get someone over here. No one showed up on Friday, nor Saturday, nor Monday. Today is Tuesday 6-24-25. I still have not heard from Trey nor anyone else from One Source. I called One Source to speak to a manager or chief technician but no call back. We are in our 70's. This is no way to run a company. It does not appear that One Source has the customers interest in mind. The One Source web site states that “We agree to accept responsibility for your complete satisfaction with the materials we use and workmanship we provide.” Well we are not completely satisfied because Trey and One Source, in a sense, deserted us. Not Cool. I will attempt again to inform One Source about Trey’s actions and to ask to speak to his supervisor or manager of the company. My reviews of Trey’s work, his workmanship, and One Source will be posted on social media as well as Google Reviews, Angi, and others. As the saying goes, “Karma, I have a list of people you might have missed.” Be Careful with this company."
