"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

Customers say: Super punctual

"Wonderful, I couldn't have had a better experience. I called yesterday because I had a leak under my bathroom sink. My call was answered immediately, and professionally, and when I asked for a certain window of opportunity due to my odd work schedule for the following day I was easily accommodated. The nicest young man came, right on time, and quickly diagnosed the problem. He had two options of repair, one being much easier and less time consuming (i.e. Less expensive), which he tried first, and it worked! He was done in about 15 minutes, and although you pay a flat service fee I think it was absolutely worth every penny. He thoroughly explained why I had the leak, and what the problem was which was very professional, as well."

"After discussing the company's last visit to our home and the translation issues we encountered prior to hiring them again, LEE's HVAC showed me they want my business.  The contractors were professional and they took every measure to ensure the job was done right. 
It's not easy finding a small service business and sometimes you have to experience not so qualified company's or unprofessional in the way they perform their jobs.  We had a problem with in hiring Lee's a few weeks ago, but after talking to someone DIRECTLY affected by a lost customer or a possible new one, it seems the misunderstanding was based on incorrect information passed along.
In any case, we were able to get our unit serviced and inspected for the summer, but what WE GOT was much more.  The contractors were respectful and professional and the job they did was thorough.  This is the basis of doing business and of hiring a service company to do business with and anything less should be discussed with the people that speak for the company.  I am glad my business was important to Lee's, because in Fresno, if you don't live in the parameters or area's that have money growing in tree's, it can be difficult to find Responsible Small Service Businesses to hire.
if you are looking for a quality and professionalism when you hire an AC/Heating repair or service, You will be very satisfied in Hiring Lee's."

"Very professional. Resolved our issue in a timely manner. Only complaint is that a part was replaced without talking to me about it ahead of time. It wasn’t a cheap part. After the work was done and I was given an explanation I would have most likely done the work. But I would have liked the option to make that call."

"Went above & beyond in service. Got the Furnace replaced, brought space heaters for the occupants, Got it done quickly & left no mess. Redid the duct work and worked well with the occupant. Thought this type of service did not exist anymore. Was pleased how quickly Furnace was replaced ."

"Oak called 2nd but came next day/ UN-prepared to do either repair or water test (requested on phone) or even replace with ready new ADA toilet that the lying receptionist booker said they have “some in stock and if not he will show a catalog of choices”. Guy came punctually with Nzo tools or appliances Or knowledge of what I asked for as an “URGENT repair/replace”. See ABC review same call. Not quite as bad as them doing same since we also still have broken HVAC too, both said they would fix ( I bought gasket already, they could have put in) or replace if they brought new toilet. Problem is not in water pipes except they need testing for lead - both said they would do this too - when I asked oak re taking a sample, how long sitting in pipes? He wiped off his soda water bottle and asked “which pipes?” !!"

FAQs for water heater repair or service projects in Napa, CA

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
