“We recently needed to have a complete air duct replacement of our HVAC system. Baran and Oscar did an amazing job for us. They were professional and very knowledgeable…completing the job in half a day. We were impressed with their professionalism and the steps they took to keep our home clean during and after their work was completed. Would highly recommend Diamond Air for any heating/AC needs.“

“Victor was amazing he explained everything and had my AC up and running in no time! Highly recommend.“

“Called in on a Saturday morning and they were available! They were at the house that same morning. Very fast and to find the problem and had the parts on site! Had the job done in a couple of hours from start to finish.“

“July 13, 2026: we discovered a leak in the water valve assembly to our refrigerator ice maker and we had a leaking outside spigot that we tried to fix (bad idea) and caused the spigot to blow off the pipe, forcing us to turn off the main water supply. So we called Steve’s. Sean arrived only about an hour after we called, assessed the situation, obtained the parts, and completed the jobs quickly. We are so grateful for Sean’s professional work and friendly service.
June 24, 2026: we had four different plumbing services performed: new one-handle bath/shower hardware including drain, shower head and spigot, installation if new main water service build up valves (outside), repairs to leaking pipes from second story bath/shower, and shut off valve and supply to all three toilets. A great team of Andrew, Will and Kaleb completed all of this extensive work in one day. All three gentlemen were friendly, neat and professional with their work. The jobs were done right and they cleaned up the work areas very nicely. The annual Steve’s membership saved us quite a lot, as the services were discounted.
February 2026: Work done: remove old water heater and install a new tankless water heater, along with all the water lines and electrical connections. Sean worked hard to get all this done in a day and the system works great! The tankless system is the better choice than the old type water heater, which had burst at a seam and sprayed hot water into our house and garage. Thanks to Sean’s great work, we can rest assured that we have a reliable hot water supply without worrying about another flooding incident.
Fall 2025: Matt was prompt, friendly and efficient. He explained the process of checking the A/C system, indicating that the key components were working at optimum levels. Very happy with Matt’s service. This was first visit for an annual maintenance contract.“

“Contracted through Home Depot, Eric arrived ahead of schedule to our remote area. He was a humble, dedicated worker who took the time to make the installation right and to explain to me what he had to do. I was given clear instructions on how to proceed in the hours following the install.“

“Max from Metz was very good and explained the issues at hand and possible solutions and cost. Would highly recommend Metz and Max again.“

“Dale Skinner arrived at the time premised and provided excellent information about my plumbing needs. I really appreciate the honesty. Marathon plumbing was clear about my needs and will be someone I call in the future.“

“Marco was quick, professional, and had great attention to detail! Highly recommended!“

“Great job with great equipment. Great installation, fast and clean! Great customer service.“

“Edward Pineda showed up to my house to address my AC concerns. He was extremely professional, helpful, friendly and addressed all of my questions. He fixed the problem in a timely manner. I highly recommended Edward and Canyon Air for any HVAC issues ir concerns. Thank you“

“Alex was polite and patient. He made sure we understood the reason for his recommendation for the thermostat replacement. He made it easy for us to understand every feature.“

“Dominic Greep came to my home right on time. He was professional, courteous and friendly. He looked at the hot water tank and knew where the problem was. After fixing it he waited to see that the problem was not recurring and made sure I’ll have hot water the next day.

I would not trust any other company with my HVAC or plumbing needs.“

“I called Marvel Air Conditioning at 4:00 PM on the Friday of Memorial Day weekend. They sent a technician out who diagnosed the problem (correctly!), got the part and had our system up and running by around 5:30! The service was exceptional and I highly recommend this company!!“

“Booked appointment and they arrived that same day! Super fast service for my AC and were affordable and transparent with their prices!!! Thank you so much for all your help!“

“I had a great experience with The Comfort Zone. During a routine maintenance visit, their team noticed that my system was missing a secondary drain pan, something I hadn’t been aware of. They quickly provided a clear quote and worked with my schedule to set up a convenient installation time.
Jim Heflin went above and beyond throughout the process. He reached out ahead of schedule to let me know he was available earlier, which I appreciated, and completed the installation efficiently. What really stood out was his knowledge of my system, he had actually installed the split unit in my garage for the previous owner and was able to share helpful background and insights.
I highly recommend Jim and the entire team at The Comfort Zone for their professionalism, responsiveness, and expertise.“

“I cannot sing enough praises for McMaster Mechanical. I work with many contractors so I know how hard it is to find someone who is reliable and competent. Bryan has went above and beyond in every job he has done for us. He does not hire other workers cheaply to do the job for him like I've had other contractors do; He makes sure that the job is done correctly himself. I have found Bryan to be forthright, honest, skilled, proficient and professional. He will explain the job to you and what it entails and keep communication with you until it is done. His expertise and transparent communication gave me genuine peace of mind throughout the entire process. Thank you McMaster Mechanical“

“So its been about a year and this hvac company is exceptional.

Ralph does a great job. Explains everything with pictures and gives competitive price for great service. That service being changing duct work and replacing new ac system all in a very tight schedule. He's very approachable and friendly in person too. His crew is also pretty friendly.

The phone operator is also a good communicator.

Joseph also does a great job and very informative. He did a routine check of the system top to bottom. He checked the vents in the attic and made sure the system was working properly. but he could improve on his overly serious expression and asking things too personal or unrelated to the job.

I hope they keep the business and the good quality going. There are a lot of licensed hvac businesses but not too many are as thorough as this group. Also alot of the other hvac people have shady botted reviews or 1 review accounts.“

“Same day service. Tanner explained several options to prevent ac/ thermostat failure.“

“Miguel was incredible. Even thought it wasn’t a plumbing issue . He gave us great advise and didn’t miss taking the time at all. I’ll always call rooter hero.“

“I have been using Goldbaum's for the last 5 or so years and I have never had a bad experience. Eric and Daniel showed up on time, got right to work and were done in about an hour. They did a Maint. check on my AC system and end up replacing the pump.“
