"Yes. Billy said everyone was great on install date. Omar was helpful and communicated effectively. Team worked well together and were efficient. Team was respectful of our property and cleaned up after work done. All of the team members being available was excellent to get install in one day. We hopefully will enjoy the benefits of the insulation and all went as anticipated with install. Very glad we had it done. Leo was excellent with pre install quote and arranging for install. We got a few quotes . We paid highest quote to have the work done quickly which met our needs. Thank you for the excellent service"

"Great job. Anthony did a complete review of the house and the current venting and recommended the proper size for the AC. The installers and electricians came 3 days later, did additional wiring and piping and installed the entire system in 5 hours."

Hydro jet uses water at 4,000psi to clean the inside of the mainline drain which connects all the home's drains to the city's sewer system.
Using a snake we can go through the cleanouts on the side of the house.
With the cleanouts snaked, and the blockage located, we can send the hydro jet through the sewer vent and flush out the blocked drain.

"The blower motor on my furnace went out. Every company I asked for a quote told me I needed to replace the entire furnace and quoted me thousands of dollars to do so. I hired Cool Air For You and the tech came out the next day and replaced the blower motor in a few hours. The AC and heating works again and I didn't have to spend 4 or 5 figures. Highly recommended."

"I was really impressed with the service provided by Nadav and he is team. I have a thirty year old home that still had the original HVAC systems. One located in the attic and the other underneath the house. Neither of these installations was simple. The Sky Clean Air team quoted me two days to remove and install new systems. The install crew was really professional, courteous and hard working. The underneath the house install was especially difficult with a tight crawl space in a less than hospital environment. These guys were not a show up at 10 leave at 3 pm crew.......they worked long hours both days to ensure they met the promised schedule.They kept me informed any issues throughout the installation process so there were no surprises. At the end of two days we had two beautifully installed systems that now cool our 4000 sq ft house in a matter of an hour instead of the 4 or 5 the old system required. I feel that the pricing they gave me was very fair and at the end of the job I felt like I got more value than what I paid. I would certainly use them again in the future."

"Excellent - We wanted to change our AC/Gas furnace system to a heat pump system and decided to use Tarpy. They provided a very comprehensive review of our needs, and spent additional time with me on the phone to help me choose the best and the most cost effective system for installation. Chris and David arrived on time and were very efficient with removal of the old system and installation of the new. They also corrected a couple of errors due to the previous installation (correcting bad welding on the Freon line, and installing a correct condensate discharge). Chris and David clean up the work area and answered any of my questions before they left. The system has been working great. Thanks Chris and David, and Tarpy!"

"Paul Johnson made a positive first impression by returning our initial Friday PM voicemail by calling us the following day, Saturday. He showed up on time to examine our system and then provided an estimate with several options. Ultimately, we requested a specific brand and Paul was very accommodating in getting us exactly what we wanted at a very fair price. We had some additional questions before making a final decision and scheduled an appointment for late on a Friday afternoon. He called shortly before he was due to arrive to let us know he was tied up on a service call and apologized that he would be later than expected. Although the repair was at a location more than 40 miles away from our home, he said he would come as soon as he was finished or, as an alternative, he could come see us on Saturday. Preferring to see him that evening, he happily drove up to meet with us that night.

Paul and his staff are seasoned technicians who take pride in their work. Their professionalism was further evidenced when we had a HERS test done on the HVAC system. This test is performed by a licensed independent third party to verify that the Installation meets very specific California Energy Efficiency Standards. Our installation not only met, but far exceeded, those standards. When I told the inspector the installation was done by Johnson Air, he said he wasn't surprised we had such excellent test results.

We highly recommend Johnson Air Mechanical and they will be the only HVAC team we will call on in the future!

"I want to give Anderson Plumbing 5 stars as they deserve it! The sales rep was knowledgable and thorough. She spent the time to go over our options and answered all our questions- and I had a ton of questions. Even when they ran into an issue replacing our ancient unit, the team stood by their word. The technicians Blake and Christian that installed the HVAC system were amazing- I can't say enough good things about these two guys as they went above and beyond. They were professional, kind, patient and kept us informed all the way. Not to mention, they left the place spotless when they left. The reason I'm giving Anderson 4 stars is due to the lack of rebate options comparable to local competitors. The two other companies we were working with offered the TECH and TECH partner program where you can receive up to a $3k rebate. I wasn't aware of this program until after the fact and Anderson was up front so shame on me for not doing my research. I hope Anderson decides to join the rebate program as it's a great benefit for their customers."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."
