My father in laws heat went out late overnight on Friday. We called them Saturday morning and within an hour, they were there! They quickly fixed his issue for a fair price. I'd highly recommend them for any of your heating and cooling needs!! My father in law is elderly and doesn't remember much but he remembered Joes name and kept saying what a great job he did!

Our one AC unit went out last night. Always when it's the hottest out. I called JK Service based on reviews I read. Spoke with Nicole and she had the tech Chris out here sooner than promised.

Chris was very friendly and knowledgeable and answered all my questions. He fixed my broken capacitor and all cool again. Great and fast service, I would recommend to anyone. Thanks guys!! Happy 4th!!

Was in complete panic mode with no heat with a business. Something told me my long time HVAC company wasn't being honest. They said I needed a part for 1k or a new system for 3k. Turns out I needed neither other than a new HVAC company. They showed up fast and got us up and running until the much less expensive part comes in. Highly recommend.
