We had 3 different companies come to give a bid for a brand new heating system for the house we…read morehad just purchased. It is an old house with an old coal heater. Each company sent the bid and each one was significantly higher. The prices ranged from $24,000 to $80,000 for a mini split system. We were desperate to get the heater installed reasonably before winter, but our budget was tight and we weren't satisfied with the bids. We went for a drive around the block and saw the Roundup Heating and Cooling truck and decided to call the number and get one last bid. Ken immediately called back and was at the house within a few days.We got his bid and immediately called and set up installation. (He was about $9000 less than the competitors and that was adding central air!!!) He did a beautiful, quick job with the installation and cleaned up every bit of his project. Unlike any other contractor that we have had.When the propane company came and set up the tank (5 months later) he came over and set our program up and made sure we knew exactly how to run it. He will be coming back in the spring to make sure it is to our satisfaction. The great news is he travels all over and isn't just in the Roundup area!! Call him!! You won't be sorry. He wins contractor of the year for us!!

I live out in Forsyth and so even being two hours away, I was glad to find a plumber to come and…read morehelp me with a clogged sewer line and a cracked sewer pipe. It's an older house that had been neglected before I bought it. They charge a travel fee of course, but still - when no one local called me back or even acknowledged my phone calls I thought I was still getting the better deal. They explained the breakdown of the costs and that they travel all over the area, and as the only plumbers who do I think that deserves a fair rate. They came out within a few days and got everything done, and were exemplary in their work and professional in their handling of me and my situation. They did all the plumbing things I could find for them, along with explaining what they were doing and giving good advice. Going from two toilets that don't work to two toilets that do, and having everything in good working order is like heaven. Now I have a great new house with excellent plumbing, thank you !

Just drove by their location and a fleet of work vehicles and vans were parked in the lot. They said they do not have anyone available to come over for at least 10 days. They do not have techs on call anymore to answer a question, they are not "always open" as advertised. They must have lost the license for selling and servicing the brand of product they sold me because they no longer are listed on the Manufacturer website as a retailer/servicer. Look elsewhere if looking for responsive boiler sales and support. I am.

Jake employed by Comet Air Duct Cleaning out of Billings came to our house in Bozeman in December…read moreand cleaned our ducts. I had it done about 4 or 5 years ago and never really saw a big difference. He discovered that the main duct was blocked so did not get cleaned last time. He cut a hole and cleaned it out, then patched the hole with screws that can be taken out next time we need them cleaned in 7 or 8 years. We could not be happier. He said the vents that were cleaned 4 or 5 years ago were pretty clean, the problem was in the blocked vents. I used to have to dust every single day, now I can go 3-4 days without noticing much dust where it used to be thick every morning. I highly recommend COMET AIR DUCT CLEANING! They have cameras that show before and after cleaning and they give you a copy at the end. They also disinfect the vents they clean. They were very responsive to my inquiry and got me an appointment within 2 weeks. Also, Jake is knowlegable and professional. Call them today, you won't regret it. Their prices are very reasonable in comparison to other like companies. Lynda B.
