"I have used Legend Plumbing in the past and they are terrific. They have great hours, weekends as well, and their plumbers are very skilled, nice to work with, and very neat. I needed a new hot water heater because mine had seen better days. I was able to set an appointment on a Saturday. Mario was the plumber. He was able to install a new water heater. I highly recommend Legend Plumbing and I will use them again."

"Parker and Sons sent out two guys to quote installation of a tankless hot water heater.  They were very responsive and flexible in scheduling time to come out.  They were also very punctual and professional.  They weren't as thorough as some of the other companies that came out, but perhaps that's just knowing what they have to do.  Where I was let down was the price. The quoted prices was 2X the cost of the other two companies I had out to quote the same job.

"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

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.

Depending on the size of your home and system, as well as any upgrades or add-ons you choose, it may take between three and five days to completely replace an existing HVAC system from start to finish. Your contractor should be able to give you an estimate before they begin the actual replacement.

Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.
