Had Kyle D out to replace inoperative piece in toilet tank. Also had him adjust additional toilet flow rate. Excellent job. Very personable. Asked him a TON of questions about other projects I am considering doing and he was very knowledgeable, explained things well, and gave me good estimates for some of my future projects! Highly recommend!

Technician came a day early. They gave me only a few minutes warning but fortunately I was home anyway. Tech seemed knowledgeable and explained what he was doing. Problem is unit is low on refrigerant. He quoted some astronomical price for the required refrigerant. I have done some research and found anyone can buy this for a small fraction of the price they wanted to charge. I feel they wanted to try to get me to buy a new system instead of just recharging this one. Granted, it is very old and there is no way of knowing how much longer it would last.

It does still work though, just needs more refrigerant added. I have also found out it is not unusual to need a recharge every few years so I am quite disappointed that they do not make that an affordable option. When I made the appointment they did tell me that it would be $89 to come look at it plus repair costs. Well, all he did was look at it, no repair but charged me $159 anyway. He then tried to tell me the extra $70 is for his time. If that it's true then they should have told me that on the phone originally.

Called to request help at 9:30AM. Chris called me at 9:43 to say he was on his way. Job was done quickly and professionally by 10:45. Very pleased with both the job and the costs. Now I can sleep at night knowing my sump water is not digging a hole in my backyard. I know it does not look like a big job but the pipe cracked right at the wall so the repair involved removing the old pipe from the brick wall and then replacing a new one with a connection both on the inside and the outside.

Great company. Have serviced our old heater several times, when it finally needed replacement they did a great job installing a new system a couple years ago. Service / maintenance has been outstanding as well. Most recent visit was from Alex, he was prompt, courteous, knowledgeable and efficient. He performed his work and reviewed overall status / performance of the unit with us. Would (and have) recommend this company to friends and family. -Ron

Kotz update my home with 3 new furnaces and AC units and a boiler. It was a very tricky job the way the house is laid out. Scott my salesman designed a new plan and followed though and executed the job. Employees were all professional and new what they were doing. Definitely a professionally run company, thanks to all thy guys who worked here!

I had the unfortunate opportunity to have my Furnace go out during the coldest days this year (4-8 degree days). I had a terrific sales rep in Troy Bridger that not only put my mind at ease but made me feel like family. He would discuss priorities that truly lined up with mine starting with family. It was a great experience and I am sure that all the Kotz reps and installers are just as friendly but next time I need service the first person I would call is Troy because of the trust I felt through our interactions.
