Joey and Josiah were very professional and proficient. We needed a new blower motor on one furnace and a new condensation sensor on another one. Joey explained everything very plainly and they got the work done very efficiently. I recommend Warner Service very highly for any HVAC issues you may have!

I gave you a 4 because I had to wait an extra hour but it was because he had a rather tough job just before our church. We had sink backup caused by numerous wipes clogging the pipes. The technician was very professional. He diagnosed the problem and fixed it in a timely manner .I would recommend Warner Service. By the way I called yesterday Sunday and he came today Monday.

Warner replaced both my Furnace and AC unit. Overall, I was really happy with the whole installation and all of the people I've dealt with. Of the three vendors who quoted the project, I selected Warner is because I felt like they were technically knowledgeable, dealt with me fairly and didn't try anything dishonest like one of the other vendors did to jack up the cost. Also, the fact that their install manager (Levi) reviewed and approved the installation for my duct sizing was a plus. I liked the Voltage monitor/surge suppressor box and the frame & stone they put on the outside unit also. I didn't see that anyone cut corners during the installation and everyone did what needed to be done. So, I thank you guys (Justin, Ben, Jose) for that.

Warner's service and installation was very professional. We are very happy with them. However, we are not happy with Green Sky who provided a 12-month financing/same as cash deal. Google Green Sky before you do business with them. To Warner Service: please know you are sending customers to a company with a very bad reputation and they have been reported to the Consumer Financial Protection Bureau.

Had service repair/replacement for Noritz tankless water. Luckily was under warranty so only paid the flat rate of $675 plus $75 trip fee. Could have been $190 or $350 labor/overtime but Warner has a deal with Noritz I guess. Warner has a 24hr call center but the main office is open during regular business hours. After getting a hold of the the office they were able to send a itemized invoice. I read other reviews but they didn't specify if they couldn't get price ahead of time because they were talking to the call center or the on call technician. If you call Warner's main office during business hours you can get prices upfront. After hours, the technician will assess and give a quote onsite only. They will charge fees for the trip if they have to come out and not repair. They did a fine job with my repair. I will call them for my annual maintenance.
