"I appreciate the experience, expertise, knowledge and integrity of this business. The home I live in is very old and I am a renter with very little knowledge of HVAC services. Sean, the serviceman, explained clearly what the issue was with the furnace and even provided advice regarding CO detectors, that I should have more than one. I am very grateful for the service he provided and I definitely recommend his company."

"Great folks to work with"

"They did a great job. "

"Woke up this morning to my hvac leaking and contacted Markool. I have never used them before and was in a pinch. They fit me right in this morning and were out at my house within 2 hours. The tech stepped in the door and placed covers for his shoes so he did not track in any dirt which was impressive! The tech was very professional and super friendly. Problem was diagnosed and FIXED within an hour. The price was extremely reasonable to the point I was shocked in a good way (expecting a higher price). Anyways, I will most certainly be a returning customer. Thank you Markool Heating Cooling Plumbing."

"We used Mailbox Xpress in the summer of 2022, and I have been remiss in not submitting a review. Jimmy was very easy to work with, responsive and friendly but professional. He replaced our old rusty mailbox with both a new mailbox and wood post. Jimmy even took the metal numbers from our old mailbox, painted them, and placed them on the other side of our wood post at no charge. He was great to work with, and I highly recommend his services!"

"The contractor was professional, efficient, and skilled. An estimate was quickly provided, and the contractor was able to schedule immediately."

"Jaye did another fantastic job for us replacing carpet with wood flooring! Beautiful work! Closet was a geometrical mess! He overcame that mess fine! Prompt, helpful and very suggestive! No "after mess" cleanup involved. A truly professional man!"

"I can't say enough positive things about my experience with Phoenix. If you're looking for a quality fence at a reasonable price look no further. Jeff and Karen were incredible to work with. We had 5 different companies come out for quotes and Jeff's thorough, no-nonsense explanation of fence types and prices made it an easy choice. When we decided to switch a portion of the fence from picket to picket w/ cap-board, I called Karen expecting the quote to be more expensive but she and Jeff said they could do it for the same price. Despite being told it was a two week wait, I got a call from Karen that they could install it the same week. Both Jeff and Karen are extremely professional and their communication made the project a stress-free, enjoyable experience. The workers, who were all brothers, were incredible. I was shocked by the speed with which they tore down the old chainlink fence, which was installed 60 years ago and had literally grown through the trunk of two trees. They methodically installed the new 218 square foot fence in one day, making sure everything was done properly. When the job was done, one worker insisted on grabbing a tool and coming back an hour later to remove a very stubborn old fence post. This level of detail and craftsmanship is hard to find nowadays. The fence has transformed our backyard and we couldn't be more happy!"
