"We were all set to spend close to $1000 on a new water heater. Told him that's what we needed.  This amazing guy came to our home. Said; 'you don't need a new water heater, just a new heat element' Gave us a year guarantee on his work and parts. He said'I don't like to charge people for work they don't need'
Who does that now a days? An honest man, I tell you. Thank you for being an honest person and a person with integrity. You've restored my faith in humanity. 
We gave him a dozen homemade organic chocolate chip cookies in our gratitude. 
HIRE this guy. you will be glad you did.

"Everything went extremely well.  I had already gotten estimates from 3 other vendors when an acquaintance who had work done previously by Energy Star talked me into getting an estimate from them before having the work done.
I was impressed right off the bat by Mike's demeanor.  There was no high pressure tactics or bad mouthing of competitors, as others had been guilty of.  He explained what would be involved and how much it would cost.  I mentioned the size of the unit that the others had planned to install.  Mike did some figuring and said that a 2.5 ton unit would work better than the 2 ton unit the others had planned on installing.  His bid included the permit fees and taxes, while the others had only given me estimates that said "Plus taxes and permit costs".  I appreciated that.  Mike's bid was the lowest of the 4, even with the bigger equipment.  
The crew showed up promptly on the day scheduled.  They were extremely polite and went out of their way to keep me informed as they did their work.  Before they left they sat down with me and programmed the computer controlled thermostat, made sure that I knew how to make any changes to the programming that I might need to, and that I knew the difference between operating a heat pump and operating a conventional furnace.  While studying up on heat pumps subsequent to the install I found out that many customers throughout the country have been given wrong information about using the "Em" setting on the thermostat.  Apparently the technicians at a lot of companies are unsure of the concept. These guys from Energy Star were right on and explained it to me correctly.  
I had been a little apprehensive going into the whole idea of switching to a heat pump but after the install was all done. I am quite happy though I went ahead with it.  I have nothing but good words to say about Mike and the folks at Energy Star and would recommend them highly.

"My 20 year old furnace died on a cold Thursday evening and I got online to find a company to replace it. After entering my contact info, I immediately received a text message from the company's owner, Casey, making himself available for me if I wanted to talk by phone. I had him call me, and he checked in to see what the problem was, what I wanted to do, and to be sure I had heat for the evening. He even offered to drive space heaters to my home if needed, even though he was at least 45 minutes away. He then scheduled to meet with me at my convenience the next day to look at my home and discuss options. During the meeting, Casey was very personable, knowledgeable,and professional about the products and services his company offered and helped me design a heating/air conditioning system to replace my old, inefficient furnace and wall a/c and insulate existing ducts. He also referred me to my utility company to see if rebates were available, which there were. The workers who installed the products were pleasant, professional, and skilled and ensured that their work met the city's requirements so that I was eligible for the rebate. I am very happy with the products and services I received from them and would recommend them to anyone having problems with their heating/air conditioning units or looking to upgrade to more efficient systems.

"He was very professional and showed up when he said he would. I showed him the water heater, he did some checks- voltage and ohms to see if elements and thermostats were good. He said he could hear some water running so we went out and opened the crawl space and sure enough there was a water leak. he went and got the materials that he needed to resolve the leak, fixed the leak. Rechecked the water heater. Great Job Thanks. "A+""

"I had a leak in my 50-gal water heater system. I found Kobi on craigslist and texted him images. He quickly responded and came over the following morning. Kobi was efficient and skillful. He replaced the damaged expansion tank and repaired the leak. Kobi also helped me install a new electric deadbolt for my front door. He is extremely dexterous. It was a very counter-intuitive installation process but Kobi was smart to figure out how the deadbolt's electronic features work. Highly recommended!"

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet.  I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."

Water Heaters questions, answered by experts

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.

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.

When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.

In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.

On average, a tankless water heater should last between 10 and 15 years. Its lifespan will be affected by how much it's used, the effect of weather where your home is on the unit—colder is harsher and will shorten lifespan—and if the heater is maintained appropriately and regularly. There are many signs your water heater needs to be replaced, so pay attention to anything that changes with your heater or hot water.

When installing a new furnace, it's a good time to consider other projects that can enhance your home's energy efficiency. A great first step is to get a home energy audit, which will identify areas for improvement. Common recommendations include sealing or replacing windows and adding insulation to the attic. These upgrades can help you save money on monthly utility costs. You might also consider installing a smart thermostat to make heating your home more convenient and efficient.
