"Lloyd and James (who did the work) are amazing! We had a pipe burst resulting in having to shut off our water. We called around to see if we could get a plumber or general contractor out to fix it but they were only interested if it was going to be a complete remodel/rehab. One even hung up on me in mid sentence. Lloyd took my call and displayed not only compassion for our situation but a sense of urgency. He explained his basic pricing up front and told us that he would try to get someone out to us in the next hour or so. In less than an hour or so James appeared and introduced himself. After showing him the area of the damage and explaining what happened he was not only able to hone in on where the problem pipe was in the wall, but also why it happened. He gave me different options on how he could handle the pipe repair and why each had its merits. He quickly repaired the burst pipe and got us water pretty quick. Professional, courteous, and capable of explaining trades talk to a novice. I highly recommend this company and I will definitely call on them in the future. Great service, reasonable pricing, and honest work."

"As a small business owner, I strongly caution others against this HVAC/R company. In over 10 years, they?ve been the least trustworthy and poorest performing contractor I?ve worked with. We experienced repeated service issues, a 25% rate hike without notice, ignored emails, and unreturned quote requests. Worse, we were billed for work that wasn?t done?confirmed twice, including by a third-party inspection with photos. Even when confronted, they deflected and delayed for months. We had to hire another company. They also mis-sized a walk-in freezer due to bad measurements and blamed their supplier. When shown proof it was undersized, they argued with no solution. They later mismeasured again on a replacement bid. Their attitude throughout was defensive, unprofessional, and dismissive. If something goes wrong?and it likely will?they will not stand behind their work. Save yourself the frustration and look elsewhere."

Water Heaters questions, answered by experts

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.

The cost to replace a water heater depends on the type you choose (tank versus tankless) and the fuel type. You can expect to pay anywhere from $880 to $1,780 for a one-to-one replacement. If you’re switching from one type or energy source to another, labor costs will rise significantly for the extra amount of work. 

The cost to install a new water heater depends on the type and its size, but homeowners pay between $900 and $1,800 on average. By contrast, you’ll pay much less for certain repairs, like replacing a broken gas valve, which costs between $150 and $550 on average.

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.

Converting a gas water heater to an electric one can cost between $870 and $4,100, depending on the installation scope, plumbing and electrical needs, and the water heater model. However, it’s always better to contact a local pro for a more accurate quote. Also, since natural gas is cheaper than electricity in most regions, you should prepare yourself for a higher monthly cost after the initial conversion.
