Apparently this is known by other plumbers, but Cardinal charges a lot more than common rates…read more I was quoted $9,000 for a new off-brand air conditioner! And the sales person was expecting I would sign the contract on the spot - I didn't. I was then quoted $4,500 for a new water heater. A local plumber charged me $2,600 for the exact same water heater. Cardinal was charging 69% more. Be sure to shop around before signing anything.

They were very quick to respond. I ended up going with a smaller contractor that was 30% cheaper…read more A little high pressure for their sale too.

I've worked with Andy's several times -- Kevin, who may be the only guy? -- and he's great. He…read moreclearly loves solving problems and I really get the impression he's honest. The first time our furnace was leaking water. He fixed it for not much money (I don't remember how much), warned us if it happened again we'd probably have to replace it, and that was like a year or more ago. All has been fine. The second time was the first really hot day of the year. Our AC stopped working. He came out right away, did a great, fast, and very competent job, and fixed our problem for $200. I trust this guy.

Olson Heating is a very small operation, but boy do they care about their community and their…read morecustomers! I noticed our heat didn't seem to be keeping up one day. We have an infant and a cold snap was heading in, so I looked up community recommendations and everyone said to call Mike at Olson. I called and left a message explaining the issue. He called me back right away and said he could come take a look at the end of his day, that same day! He came and analyzed our furnace, and everything that was wrong with it. He was very honest and helpful, which I appreciate. Not a hard salesman, just trying to help our family make the best choice for us financially. Basically, we needed a new furnace. He couldn't get us in until a few days later(we were just surprised he had furnaces on hand!), so he reset the furnace to get us by until then. He installed the furnace in just a few hours, and it was working like a pro! But just a few days later, we noticed our room upstairs wasn't getting any hot air from the vent (our house is old and doesn't have enough vents as it is), so we called Mike. He came over that same day again and looked it all over. Turns out it was a simple fix and the heat started coming through the vents again. But that just shows you the attention he gives to each customer. We will definitely work with Mike on all heating issues going forward, whether it's this house, or the next.

WOW!! RUN!! Don't walk!! These guys are AMAZING!! So.... I live in a condo complex that…read morewas built in 1988. The owners were instructed that we needed to have our dryer vents brought "up to code" as most of the vents had become disconnected... and were venting somewhere inside the building.. but not venting out side the the building. Argh... a challenging task for sure. I called several companies to come out and give me an estimate. Every single company I called said "I will find your disconnect, but you are responsible for replacing your drywall, painting, etc" Not good news. Then... Ducts On Call came out... and they spent 4 hours researching... trying to figure out which vent was mine that exited out of the back of the building. But since every single dryer vent was disconnected in the interior of the building... there was NO way they could figure it out without tearing up the ceiling in mine, and my neighbors units. I was SO frustrated. But then Nick suggested we put in a new vent duct from my unit straight out the front of the building. It was my only option. He said we would need to schedule a time in the future... but I told him I needed it done in the next 3 weeks. He said... "I will make this happen for you" Well for starters... he DID NOT CHARGE ME for the 4 hours he spent trying to figure out which vent was mine. HE SAID... "I didn't solve the problem.. so I will not charge you" What?? 4 hours of your time for free?? Moving forward..... Nick and his crew came back 2 weeks later to install my NEW, up to code dryer duct on a new path out the front of my condo. I was SO not looking forward to having my ceiling ripped open to have the duct installed. So the day had come. Nick arrived before his scheduled time and he went to to work. I asked him... "How much of my ceiling do you need to open up?" He said... "I'm not opening your ceiling... I'm going to drill a hole in the exterior of your building, and slide the new duct straight back to your dryer connection" I was beside myself! I could go on and on... but let me tell you, this guy is the real deal!! He is incredibly gifted at what he does... super friendly... hard worker, and gets the shit done!! For what I thought was going to be a day of HELL... turned out to be a day of BLISS. I CAN NOT recommend this company any more than I do!! They were AMAZING... and the job was smooth, and quick, and so much easier than I dreamed it would be. Let me state again... that I called several companies to get the job done.... and these guys were one of the newer companies I called.... but I hit the jackpot!! Trust me!! If your need Duct work done... these guys were stellar from start to finish. And no... I'm not related to them... I'm not his high school friend... and I knew nothing about them, but I took a chance... and boy... am I glad I did. Amazing! THESE GUYS KICK ASS!! Give them a try!! Thank You Ducts On Call!!
