"This is the first ever review I have ever written. My encounter with Harris at HG plumbing and Heating solutions was so exceptional that I feel so compelled to share my experience. I have used many plumbers over the years to service my house but Harris stands out above all. I recently called him for a clogged kitchen sink that would not drain. He responded immediately and was able to fit me in within his busy schedule. It turned out to be a bigger job than anticipated but he corrected the issue. During the entire process, he explained clearly and thoroughly each problem and options on how to correct it. He used the most advanced techniques and updated tools to solve the problem. He took great pride in his work and was not satisfied until it was completely repaired. In summary, he is extremely professional, a skilled expert, punctual, and tidy. His work is extremely meticulous, thorough, neat, reasonably priced, and to code. Above all, he has great communication. I highly recommend him for all your plumbing and heating needs. Hands down the best plumber out there period! Thanks again, Harris!"

"Got to my place later than expected because they were stuck on another job which is understandable. Did not finish my job until after 12:00 am in the morning. My job took longer than anticipated. I was given one price at the beginning and that's what we anticipated paying because I am on a budget. After the job was finished we were handed a bill that was much more than what was quoted. I was a very upset about that. I know that it took longer and they had to go back and forth to the truck to get supplies, the only thing is I wish I was informed of this during the job so I would know what to do. What if we didn't have the money? Anyway the job was done good and we are pleased with the outcome. So far our sink is working properly and good. We had a double sink installed, the faucet and we have a water omosis machine that had to get hooked up, so it did take a lot of time because piping had to be changed from a single sink to a double. I would recommend this company."

"Affordable HVAC repair service. You can actually ask them to do little extras at no additional cost. After I called them for emergency repair of our AC unit, they offered a complementary cleaning for the unit. Amazing customer appreciation. Totally recommended!"

"Called because heating system would not start up.  The company came a short time later and found out the problem was a simple fix which involved adjusting the angle of a waterline.  I highly recommend because the service was great and I had a very good overall vibe throughout the whole process.

"Ackeno provided me with a free quote and delivered exactly what he promised, including a drain pan with drain system to protect against water leak. I was considering between tankless and conventional water heaters, and Ackeno was very knowledgeable about both systems. He's very cost-conscious for his customers, and the price was reasonable. The water heater he got for me is a high-quality commercial one, which is more durable against corrosion. I'm glad I hired HSM."
