"Was selling my apartment and wanted to service heater prior to listing. Moore provided great technicians who tried everything they could to reset and fix some mechanical issues. Provided lots of info and updates while they worked, showed me everything they were doing, where problems were, etc. In the end, the heater was too far gone and a whole replacement was recommended. Moore was able to schedule the replacement within a week. Whole project was completed in 4.5 hours and came in under their initial estimate. 10/10 would recommend them to all friends and family."

"I would echo most of what I have read in the reviews about Brian. He is prompt, courteous, and professional. Though he is a bit on the expensive side, I believe he is well worth it. An honest, experienced plumber is like money in the bank as far as I'm concerned. Because, while I could have found someone less expensive, experience has shown me that when it comes to plumbers, you definitely get what you pay for. And Brian is worth every penny."

"Green Core HVAC was awesome to work with! The team did a great job helping us pick the perfect AC unit for our home. They showed up on time, got the new AC installed quickly, and left the place spotless. Our house is cooler and more comfortable than it’s ever been. You can tell these guys really care about doing a great job. I’d 100% recommend Green Core to anyone needing AC work. Super professional, super friendly, and they really know what they’re doing!"

"I was very pleased with Ray's plumbing services. He made it hassel free, he was efficient, professional, finished the job promptly. He was not pushy, however he was very knowledgeable and answered all my questions without* making me feel like an annoyance, as others have made me feel in the past and wanted to rush through and collect money. I Highly recommend Ray's Rescue Plumbing to my loved ones and to anyone looking for a trustworthy company. -Services provided: front of hous, entire faucet valve & pipes equipped/replacement; had unresolvable water leakage. Simply from being an older home the pipes had visible begin showing corrosion from due time"

"Elsy ( I believe she was the plumber from your company via Angi) arrived as scheduled, on Saturday, 09/28/2024. She attempted to repair my garbage disposal unit but was unable to do so as the unit's wiring was worn out. I advised the unit is 40 yrs old. She recommended to purchase a new one. We made a trip together to the local Home Depot store and I purchased the same brand s she recommended. She installed it in record time (within the 2.5 hrs) and completed the job. She also cleaned the work space and carried the old one to my recycling bin. Very satisfied with her work. Also, I want to know if I will receive a billing statement for my records? Thank you for your time & assistance."

"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 can use multiple tankless water heaters, but that doesn’t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you’re adding many more points of failure in the system, making plumbing issues harder to diagnose. More heaters mean more maintenance, and insurers may want a word regarding the increased risk of water damage. A single, larger unit makes more sense in most situations.

Every city and state will have its own set of installation codes and laws. Some won’t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a local water heater installation company and local building codes to confirm which permits are required and what the specific laws are.

While a water heater explosion is rare, it is a serious danger. Be aware of these critical warning signs:

  • Sulfur or Rotten Egg Smell: This is a major red flag, especially for gas water heaters. It can indicate a gas leak, which could ignite and cause an explosion.

  • Leaking Pressure Valve: If the temperature and pressure (T&P) relief valve is leaking, it may not be able to properly regulate internal pressure, creating a risk of bursting.

  • Shaking or Rumbling: Loud rumbling or shaking from the tank can be a sign of extreme pressure buildup.

  • Excessive Heat: If the exterior of the water heater feels unusually hot to the touch, the unit may be overheating dangerously.

  • Rust-Colored Water: This can be a symptom of severe internal corrosion that compromises the tank's integrity.

If you notice any of these signs, especially a gas smell, you must act immediately. Shut off the gas supply to the water heater and call a professional plumber right away to prevent a potential disaster.

You can and should vent the gas from your hot water heater to the outside of your home. Traditionally, these gases were vented back to other gas appliances, like stoves or furnaces, but many jurisdictions have outlawed this practice due to the risks it provides. 

Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.

Tankless water heaters are more expensive than those with a storage tank, but they come with some impressive benefits that most homeowners find worth the higher investment. Most importantly, they provide unlimited hot water, so you’ll never run out like you would with a storage tank. Tankless heaters are also more efficient, so comparing gallon-for-gallon, you’ll spend less on hot water with a tankless heater. Tankless water heaters are also smaller, require less maintenance, and tend to last longer than storage tank water heaters.
