Excellence service. Called him because our hot tub had stopped working. Greg was at our house within 2 hours and Our hot tub is all fixed. Very Punctual, Knowledgeable, and Honest. I would definitely use Hydro Tech again if my spa needs servicing. read more

Unfortunately, Greg took the pump from the jacuzzi in our rental house, saying he'd bring it back in a few weeks but never did. That's been around 5 or 6 months ago. He is now unreachable, and he left the tub in an unusable state. It's puzzling because he has such great reviews. We just want him to make this right. read more

We had put off getting our spa repaired, assuming that it would be pretty expensive. Based upon Yelp reviews, I contacted Greg. He came out quickly, worked efficiently and charged me an extremely reasonable rate. He will definitely be my go-to spa repair guy in the future! read more

Greg is fantastic. He fixed my Sundance Spa in less than an hour and I can promise you I've waited a year to make the call. The price was very reasonable. With this guy you get a person who is very knowledgable about how your system works and gives you pointers on how to keep your machinery alive. I'm glad to have Greg on board. My spa was heating up to 105 when reading 92! Thank you for your great service Greg. I suspect I'll be seeing you again, but hopefully not for a while! I don't really use yelp, but this warranted a review. todd read more

Greg came to fix a hot tub problem that another repair man has been trying for more than a month. He quickly spotted where the problems were and fixed it in 1 day. Pne the second day, he came out to check and put all the hot tub boards back together. Greg is professional, knowledgeable, and courteous. I would hire Greg again in a heart beat. read more

called the guy TWICE and sent email to invite him over to give me bid on pool repair. He never bothered to respond. UPDATE: Two weeks later, I email him again - still no reply. How he get 5 stars is enigma?. read more

Highly recommended! All I can say is Greg was excellent!!! fast diagnosing and fast repairing . I thought the pool heater died and Greg was able to fix it by Replaced sensor to pool heater! Very professional and excellent price!!! His rates are very reasonable and he does an excellent job of explaining the issues and options to fix. Very satisfied with his service and would use him again and recommend him to a friend in an instant. Thank you Greg Macarthor 408-315-1421 read more

All I can say is that our Spa didn't work right for 7 years, then a friend recommend Greg and now we have a Spa working in perfect conditions. He took the time not only to work in detail but read the manual and with no rush he found the problem. I need to buy him a Christmas present.mThanks Greg.

Had an urgent need to get our pool heated up in prep for an infant swim class. we tried to start it up 2 days prior and couldn't get the display on the pool heater to show anything. did some yelp research, called Hydro Tech (Greg) and a few others. Greg responded within 2 hours to my call, and even though arrived later than quoted, he was able to come out that same afternoon. After troubleshooting through multiple successes only to be met by different error/issues, he had it up and running within 2 hours. I would recommend Greg due to his availability for our urgent need on a days notice, his professionalism, and his ability to get my equipment working. We will surely keep his number around if ever needed again. read more

Saved me money and made my week. I got a quote months ago from a different person and realized repair was going to be out of reach for awhile. When money was available. I started calling around again Greg was so much less than the last guy that I almost questioned whether I should hire him. Would the end price be higher or would the quality be low? The yelp reviews were good so I took a chance and so glad I did! Greg went above and beyond and my hot tub has been wonderful! I would highly recommend not going anywhere else. Best spa repair I have used by far. read more

Greg just came over to repair my Sundance spa and managed to save me a few hundred dollars. I am very pleased with his innovative solution that saved me from having to buy a new pump and/or switch. He had seen the same problem so many times before that he went out and had new eProms burned that eliminated the need for the parts that went bad. This is a guy who knows his stuff. I couldn't recommend him more. read more

Greg really knows his craft! My older Cal Spa wasn't turning on. Investigating further I found an electrical circuit disconnect box had developed a bad connection. I had an electrician come out and replace the disconnect box with a nice new breaker box and repaire some wiring. Spa still wouldn't turn on, and was tripping the new breaker. After troubleshooting it awhile myself, I called in the pro. Greg came out the next day and immediately spotted the issue. Electrician had wired the neutral incorrectly at the breaker. He changed the location of one wire and spa turned right on. He noticed a leak around one of my pumps, replaced the fittings, and tightened everything up. Even replaced a missing screw on the access planel that I lost years ago. I'll go to Hydro Tech for all my spa repairs from now on! read more

Greg did an excellent job of diagnosing and repairing two issues I had with an old spa. He fixed both problems without just replacing components. I would highly recommend him for any spa issues you have. More than likely he will be able to repair your spa for a much lower price than just replacing components. His rates are very reasonable and he does an excellent job of explaining the issues and options to fix. Very satisfied with his service and would use him again or recommend him to a friend in an instant. read more

We just inherited a Sundance Cameo spa and were struggling to get the water to heat. We had consulted with another company, which identified the problem as a clogged circulation pump, but their charges to fix the problem were just out of this world. We ended up ordering the part online and trying to fix it ourselves, but alas, we are not gifted in spa trouble shooting. This is where Greg came in-I called him after seeing his amazing Yelp reviews and he was able to make it out the next morning. Greg definitely knew his way around the spa parts; he got the pump replaced/working and even did some trouble shooting for us on the spot. We definitely appreciated Greg's speedy and professional, not to mention cost-efficient, service and will be saving his number for any other future issues we may have! Thanks to Greg, we were able to relax in our hot tub last night after weeks of frustration! read more
