"We are incredibly grateful to Pedro Galvan and his team for stepping in during a moment of urgent need. When our hot water system suddenly failed, leaving us without hot water for daily essentials, Pedro responded with a level of professionalism, clarity, and compassion that is truly rare. From the very first call, Pedro was attentive, transparent about pricing, and committed to solving the problem quickly. He provided us with the most cost-effective and honest quote out of several we obtained—and, even more importantly, was able to come almost immediately when others could not. His workmanship was precise, efficient, and tidy. It was clear we were in the hands of someone who genuinely takes pride in his craft. In a world where so many service professionals overpromise and underdeliver, Pedro Galvan delivers exactly what he promises—and does so with warmth, integrity, and a deep respect for his clients. We recommend him without hesitation to anyone needing plumbing services."

"Green Core Heating & Air did an excellent job installing our new gas furnace and completely replacing the ductwork. The owner communicated clearly throughout the entire process and was always quick to answer questions. The crew showed up on time, worked efficiently, and kept everything clean during the installation. Pricing was very fair compared to other quotes we received. I would definitely recommend them to anyone needing HVAC work."

"I would highly recommend Ray’s Rescue Plumbing. He was very clean, prompt, courteous and knowledgeable. We had several issues ranging from leaks, repairs and installing a tankless water heater. Ray’s prices were competitive and he actually saved us a few thousand dollars from a previous bid from a ‘not so honest’ plumber."

"Finally!  A plumber that shows up on time and does efficient and neat work.  Also doesn't aggressively try to upsell you on other services.  One more thing, we supplied the faucet to be installed and there was no attempt to charge us for the lost commission  the company did not get on the sale for the faucet.   In other words, just what you should expect from a plumber."

"It went very well; the thorough HVAC system checkup revealed some questionable component that were best suggested to be replace with new ones. I am not confident that my HVAC system is set for more that good performance going forward. I appreciated the non-pressured advice and suggestions in coming to my decisions. Thank you, Joaquin Ortiz."

Water Heaters questions, answered by experts

You don’t have to replace expansion tanks at the same time as your hot water heater. You may be able to go six to 12 years or more before needing to replace your expansion tank. At $150 to $450, hot water heater expansion tanks are usually much more affordable than the cost of hot water tanks themselves, which average about $1,190.

An average-sized empty water heater weighs around 150 pounds. Tankless water heaters are much lighter, weighing between 10 and 50 pounds. The smaller size and added convenience come at a price, though—tankless water heaters average about twice the price of their traditional counterparts.

When replacing an old unit, you might want to switch from a gas water heater to an electric water heater or vice versa. To do this, you will likely need to add infrastructure to the area. For example, you likely don’t have a gas line that served your old electric water heater. You’d have to call a plumber to put in a new gas line. If you’re replacing a gas unit with an electric one, the plumber will need to safely cap the old gas line. You will then need an electrician to add wiring for the new electric unit.

Unusual noises, lack of hot water supply, efficiency loss, and visible leaks are signs of necessary replacement beyond mere repair.

A thermocouple is a pretty simple device. It simply tells the control valve if heat is present. Most water heaters can use a universal thermocouple, provided it's the correct length. Getting one that's long enough for your appliance is crucial for success. However, some water heater models require model-specific thermocouples, which is why it's essential to take your existing one to the store to find the right match.
