"I have what turned out to be a 30 year old water heater replaced by this great company and they did it the same day of the quote. The installer had the water heater I wanted on the truck and did an excellent job of putting in the new unit, cleaning up and even replacing copper flex tubing and installing a new overflow pipe out of copper as well, no additional cost. This company specializes in water heaters and couldn't do any additional work on supply lines and they clearly state that on their website. I didn't need that type of additional work."

"Jaymie first visited to review our need for correcting a pre-existing faulty installation of a tankless water heater. He grasped our concerns at once, joined us in brainstorming a relatively simple solution, and produced a financially reasonable bid on the spot. We accepted it as far more reasonable than other bids. He arranged to have the work performed by his company within a few days. At the appointed time, Jaymie himself arrived to do the job, which pleased us greatly since he already knew exactly what needed to be done, making it unnecessary to brief a new workman. He is a very competent, friendly, and helpful person. We would not hesitate to call on him for any future plumbing needs."

"Robert was an amazing plumber to work with. Extremely professional, knowledgeable, responsive and honest. All traits that are hard to come by in this profession. Ever since I found his business, Iâ ve never even bothered to look elsewhere. He never tries to upsell you, gives you options and always cleans up meticulously. Iâ ve recommended him to all my friends and family and they were all happy with his services. So far heâ s fixed my clogged sink, installed and repaired my garbage disposal, came immediately when my storm drain busted, and gave me quotes and advice on a tankless water heater. Hopefully I wonâ t need his services any time soon though!"

"The cost to replace three natural gas wall heater was slightly less than Gree mini-splits heater cooler. The installers were courteous and professional. Delayed several days as the equipment haven’t arrived yet. Job cost as agreed, but took half day longer due to the complexity of installation. Results are excellent. The mini-split units works as specified. Will use Albert Nahman heating plumbing again in the future."

"Called Trio Heating on a late Friday afternoon and they sent out two technicians (Jose & Dallin) the next morning to fix a gas heater that would not turn on. Their communication from beginning to end was great. They sent me a text 45 minutes before their arrival time and I was able to track their ETA which was extremely helpful. They explained to me what the issue was. I was able to run out and buy a new thermostat for them to install. They did a great job, cleaned everything up and put everything back together. They also typed up everything they worked on and took multiple detailed photos of the unit and emailed 10 minutes after they left. I think what they charged was extremely reasonable for the quality of work. I really appreciated not being charged a higher fee for coming out on a weekend. Will definitely use them again for my HVAC needs!"

"I had a water pipe break after hours on a Saturday night. They were told me the price up front. It was comparable to what others charge. They were out early Sunday morning. They completed the work quickly. After they left I noticed a secondary issue. The same technicians returned less than an hour later and fixed that problem at no additional charge. They were very professional and I would highly recommend them."
