Gil arrived about an hour late, but I am glad that I stayed behind (but ended up being late for work) because I was satisfied with the service. He took his time with the diagnostics and in the end sent me a report that was very thorough. The special did not come with a free cleaning, but fortunately my unit isn't so bad. I recommend giving them a try, especially if you could get Gill to come by since he seems very knowledgeable and his actual owner of the company. Thank you again!

Some wires to my condenser had crimped and he was able to repair. He also checked my furnace and provided a quote to add a secondary drain pan and low voltage wires to prevent a leak occurrence in the future. I was provided a quote each time and it was very fair. He explained everything and told me how to keep my system in tip-top shape going forward. He was on time or kept me posted with text messages if he was running late. Thank you, Aleks for keeping me "cool"!

Estimated 2 weeks job turned into 2+ months of hell. we had to terminate and redo everything , 70% of work was not to code. We had to hire out to new plumber and drywaller. pvc flex pipe had to be replaced wrong size used not to code, water regulator had to be reinstalled properly with gauge. All valves had to be redone , strapped and new drywall patches done. We had no running shower for a week no hot water to kitchen for over 2 weeks. There was so much more but you get the picture. I hope this company changes their job performance and truly starts doing business by the book. * Leon M. Is not a licensed plumber and the CSLB website doesn't lie. *

GJS Heating and Air Conditioning was recommended to me by someone in the trades. Since I'm a…read morebeliever in word of mouth, I called the number given to me. John Carlson came out that day, and gave me a bid. I thought the numbers looked reasonable, and he started work right away, putting in a ductless HVAC unit. John was professional, and when he finished the installation, it was operating perfectly. Several weeks later, I started having trouble with my HVAC system. The fan was working, but the unit wasn't cooling. I wondered if I was doing something wrong, and looked at some You Tube videos. Nothing I saw, or attempted, seemed to work. It didn't help that this breakdown had happened in the middle of a heat wave, and I seriously doubted a quick fix was imminent. Nonetheless, early this morning I sent a text to John, explaining the situation. Given the excessive heat, I knew how busy he had to be. Despite that, he responded to my text and said he would try and shoehorn me into his schedule. Within hours, he was at my doorstep, and working on the problem. It turned out that the coolant had escaped through a defective flange. The system is now working perfectly, and I'm a cool cucumber despite it being 92 degrees outside. You know you've picked the right HVAC person when they respond with such alacrity to a problem. It might seem that the safe HVAC choice would be one of the big firms that advertises relentlessly on TV. Trust me, though, you'll be happier going with the "little guy" that is GJS Heating and Air Conditioning.

And somehow no one has ever put insulation in our home since it was built in 1938. I saw another reviewer contacted him about the same thing and had a good experience even though it's not really in this business's current scope of work. I had the same great experience. Spencer looks at the big picture, unlike individual contractors who handle a single facet of a project like this.You can tell he's passionate about energy efficiency and helping people make their homes more comfortable. He also knows what he's talking about and is knowledgeable about products and local contractors/vendors. After our conversation, I was more educated about the variables involved with making our project work. There was no sales pressure, but we are going to have Spencer review whether a solar system is right for our home. If you're considering a project to make your home more energy efficient, I highly recommend calling Energy Integrity.

We had thought about getting the job done for months before we pulled the trigger. Spencer was great at keeping in touch with absolutely no pressure. Once work began, his team was quick and clean - you wouldn't have even known they had been there. Now that the summer is starting to heat up, I'm so glad we got the work done. We've quickly developed a routine of coming home, opening specific windows and running the fan. Then at dinnertime, we switch up the windows and cool different parts of the house. It's to the point where I'm actually cold at night, despite the high temps all day! That never used to happen! Bottom line - great communication and high quality work!

After SDG&E as project manager for City Heights CDC I called Glenn to repair slab leaks, replace commercial water heaters as I knew he would complete the work correctly, on-time and to CHCDC's satisfaction. Now retired and needing a replacement water heater, you guessed it GRJ Enterprises did the work. Honesty and integrity are what Glenn Janssen is all about and will stand-by his work, so ease your worries and contact GRJ!!

I was beginning to panic as my elderly father's water heater was starting to go on the fritz…read more (pilot light went out) and I would be leaving to go out of town in a few days. I had worked on getting it fixed all weekend and only had a few more days to get it taken care of. We were initially told by an SDG&E tech that the safety in the control valve was becoming weak and needed to be replaced or the pilot light might go out again and the ignitor button didn't work. We had a plumber come out and do other recommended work, (which initially was quoted at $140 and by the end blew up to $444) he said he does not troubleshoot that part of water heaters. I was told this in the beginning so I knew I'd have to call a second plumber. I had also been told by other plumbing companies that I would need to just buy a new water heater and was quoted a price of $1200 for a 40 gal. tank and install. It also seemed that the control valve is a part that is hard to get (A. O. Smith Promax, 30 gal. 2008 model) The second plumber wasn't able to get the part and if he could, didn't want to risk putting it in and have it not work, however he referred me to GRJ. I spoke to Debra. She was very knowledgeable and knew the common issues with this water heater (the screens at the bottom can get clogged with dust) and that the part SDG&E recommended to be replaced rarely fails. She quoted an extremely reasonable price for a service call and on the parts which may not be needed (pilot assembly, gas valve). I set up an appointment and am very satisfied that I finally found the answer to the problem of fixing this water heater and at a reasonable price with such great customer service over the phone by Debra! I wish I had their number early on. I would have called them first!
