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.

He refused any compensation for his time and had a professional attitude and smile throughout. It 's great to know there are fair honest repair people left in the world.

It was unfortunately not expected to get an AC repair tech to come down within the same day during…read moresummer time. First company I called was booking 2 days out. I instead opted to call someone local to me (Escondido) instead of someone having to drive from 20 miles out. I called Monday morning, was booked for that same afternoon as our AC decided not to work at 1am. Surprisingly, Jim arrived just before 12pm as he was already in the area. I very much welcomed the early arrival as the heat was starting to escalate. It took Jim literally 3 minutes to diagnose the problem of our AC, a burnt relay contact (I wrongly predicted a faulty capacitor). This is how you know you are dealing with an experienced professional when he brings out only the necessary tools and leaves the work site clean. Jim was in and out in about 35 minutes (should have been less than 30 if I hadn't asked questions). As they say in the industry, there are no second chances for first impressions, Because of this, I'll give them my business for AC maintenance moving forward due to my great experience, promptly saving me and family from roasting in an above average SoCal summer. Cost (part + labor) was very fair and no hidden or surprise charges. More blessing to you Jim and your crew.

My house was built in the early 80's. I purchased it in 2016 & honestly believe the HVAC unit is…read morethe original. One day, my unit just stops blowing hot air. Now, living in San Diego, this really isn't an issue but every now and then Escondido has extremely cold nights. I decided to have the unit inspected looking for advice on repairs. Listening to KSON, they recommended Mauzzy ( spelling???) heating and air so I called them for a $99 inspection. Long story short, the guy said my unit was too old and he recommended replacing the entire unit for $16-20k. I said nope and he left. I was at my favorite coffee shop telling a friend about this when another gentleman overheard me. He recommended Jim to me. Jim comes out, runs a few test & in less than 10 minutes finds the issue. He had to order the part so I had to wait a few weeks ( no big deal ). He gets the part in, schedules a convenient time for me to install the part costing me a total of $220. I cannot recommend Jim enough, he is truly honest, reliable, & dependable. Imagine being told you needed $16k replacement when all you needed was $200 part.... I can't recommend him enough. I've already told all my neighbors about him.

I had 6 contractors come by to bid on the project and he seemed to be most knowledgeable and upfront about his approach. I initially chose him based previous reviews about his quality workmanship and clean installations, and he more than lived up to the hype. He never tried to upsell me on unnecessary equipment or services. He took the time to thoroughly explain my options and focused on what I needed, not what would pad his bottom line. I also requested that permits be pulled and proper ducting installed to satisfy my home insurance requirements, and he handled everything seamlessly. When the third-party inspectors came by, they were thoroughly impressed--commenting that the installation passed with flying colors and was one of the best they'd seen compared to similar homes in the area. My project also required a new electrical conduit, which Roger was able to facilitate efficiently and tucked neatly to avoid an eyesore. If you're looking for an HVAC professional who takes pride in his work and focuses on quality installs, I can't recommend Roger enough.
