"The installation went well. Justin from sales is awesome and took all the inputs and scheduled the installation appropriately. The installation team Doug and JD are excellent. They worked very hard in the hot sun and installed very patiently. Very cooperative, cleared all the questions we have. We had an issue with the drainage of the purifier as it occupied our washer and dryer which prevented our washing machine installation and Costco denied the installation. But upon contacting prostar Doug or JD came and resolved the issue in no time. He installed the washer and dryer as well. Really appreciate the team and their services.."

"Legend Plumbing will always be my first call for plumbing needs. Awesome response time and very happy with the outcome. First time was installing a new water heater which also added the proper safety drainage I didn't have before. This time Jesse took over my kitchen faucet project that I was likely going to make worse before having to call a professional. Appreciated his expertise and advise. Installed new (very much needed) valves as well as the new faucet, after removing the old one that had rusted under the sink making it near impossible for someone without the proper tools. Highly recommend Legend Plumbing."

"Before the water heater installation, the technician said that in order to meet code requirement the water heater needed a vacuum breaker, which cost $95 above and beyond the $900 coupon price.  I said to him that the coupon price should be for a water heater that met all regulatory requirements instead of charging me extra for the vacuum breaker that's a code requirement.  He said no.  Since I needed the new water heater badly, I asked him to go ahead to install it and I would call his manager to talk about this.  When I called the manager he said he had to talk with the technician when he returned to the office the next morning.  When I called the manager again Monday morning after he had a chance to talk to the technician, he reduced the charge for the vacuum breaker to $30, perhaps the cost of the parts.  However, I still think that the vacuum breaker should be part of the package cost because they are supposed to supply and install a water heater with all parts required by prevailing codes because it's not an optional equipment.  Also, the technician used a pressure regulator, a flexible copper hose, and a power supply cable from my old water heater instead of using brand new ones.  Since the coupon did not list all these details, I couldn't argue about this, but the previous company which installed my last water heater supplied all these brand new, including the 3/4" brass ball valve for free while I had to pay $95 for it now.

"I  am selling my house and I needed Steve to come out and service the air conditioning/heating unit as well as clean the coils.   I reached his voice mail and left a message.   He called me back promptly and we set up an appointment for the next day.   He arrived at the appointed time and accomplished what needed to be done in a timely manner. 
I have used this company for over a decade and have recommended Steve to family and friends.   He has worked on residential and commercial AC units for them.  They have all been highly satisfied with his work and fair price.   He is reliable and honest.   He doesn't try to talk you into making repairs that aren't necessary.

"The technician arrived on time and very professional. We had an issue with a leak on one of our units. Instead of pressuring us to go through his company, he explained what was going on and provided a quote. He was supportive when we wanted to wait on scheduling anything so that we could contact the original installing AC company to find out about the warranty."

Install Boiler FAQs, answered by experts

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.
