"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

"initially ok though while onsite I had to ask "what is that rattling noise"...I don't understand how they didn't realize they had dropped a piece of cut duct sheeting into the unit interior. They used bad taping on the modifications they made to the ducts and it all blew apart. called to have them back to fix several times and they never bothered to answer"

Water Heaters questions, answered by experts

You should replace your gas water heater when it’s reached the end of its lifespan, which is a maximum of 12 years in most cases. If your unit is over a decade old and showing signs of inefficiency, leaks, or frequent malfunctions, it may be time to replace your water heater. Research how to best maintain your gas water heater to help extend its lifespan.

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.

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. 

No state requires you to vent an electric water heater. Other installation requirements for water heaters will vary, though, depending on the state and local jurisdiction in which you live. Some places require permits, while others don’t. Some may force you to place the appliance a certain distance from any walls or other appliances, while others don't. When you find a local professional to install a water heater, this expert will ensure you follow all the local regulations.

Professional installs conclude in mere hours, with complexity differences possibly prolonging efforts slightly. Site condition often dictates the exact duration.
