I had my HVAC system installed just about two years ago, with an extended warranty. I went with…read moreCalloway & Sons solely based on their positive Yelp reviews as my friends really didn't have anyone to recommend. I'm not going to lie: getting this system installed in a home we were living in at the time was not a pleasure and I won't ever go through it again. We had to get the duct work done which is a horrifying mess (there's no way around it) and to Calloway & Son's credit, they did suggest we go with a split system. Live and learn. We also thought we were getting a system with zones which didn't happen and it was never fully explained why, but in these old homes with impossibly high ceilings and two levels, your bills are going to be extremely high if you have one single unit. It is what it is. I certainly don't blame them for that! But on to the most important stuff: the system is pretty good. Again, old house, not the greatest insulation and taking all that into consideration we are comfortable 80% of the year. The other 20% of times are where things are a less than awesome: this year's blizzard and any extremely cold days mean for a very hot upstairs, requiring us to run the window AC unit. And on those blistering hot summer days, there's no way we're comfortable upstairs without the window unit. Again, my house... it's ancient. It wasn't made for these types of systems. Last summer, there was a day in August when the system stopped working on a Friday. I was more than a little disappointed when I was told they couldn't give us a service visit unit until Monday. If you live here, you know it is literally unbearable to not have AC on a summer day. Luckily the very kind lady on the phone worked with us and fit us in. I also now pay for insurance that ensures priority service. I was only able to afford to get the HVAC on the owner's side of my two family house done and that was about 25K. The financing was not great... if I hadn't paid it off ASAP, it would have been almost double that. So try to pay it all upfront if possible. At least the option is there if you need it.

Owner/supervisor visited to ensure all was going well. They cleaned all dirt/debris inside house and picked up all outside trash including old unit. Travis Oalmann stayed to ensure the new unit was working properly. We highly recommend Oalmann AC & Heating. They are honest, dependable, and did good work.

There was zero communication that what they were doing would result in a charge -- not even a heads-up. When I asked for an estimate, they failed to provide that as well. This is completely unacceptable and misleading. It's not about the amount -- it's about the lack of honesty and transparency. No company should assume they can charge for something without first getting the customer's consent. I won't be using them again and wouldn't recommend them to anyone who values straightforward and honest service.
