"

I called James at 8:20 am Saturday morning. He said he had two others ahead of me but would be at my house at 1:00 pm. He called at 12:50 to tell me he would be here in 5 minutes. He arrived at 12:55. What a pleasure to have someone show up on time, For the next 3+ hours, James worked on all three of my computers. The first computer had 6 viruses which were downloaded when we tried to download an internet game. James removed the viruses, showed me how to prevent this from happening in the future, and then correctly installed the internet game. IN addition, he updated all programs, removed unnecessary programs, and installed

new programs to improve the quality. Jim then did the same work on my other two computers, one of which was found to have 232 viruses.
I am not computer literate; therefore, I cannot recall the details of additional work James did on all 3 computers. All I know is the computers are running smoothly and quickly. The cost was very reasonable.
I will use James in the future, and highly recommend him to others.

"I required a new water heater installed and Diana builders were able to give me the exact water heater I wanted at the most competitive price. Dave took the time to explain what he thought the best solution was in plain English, gave me a quote a few hours later after researching his exact costs and stuck to his quote."

Install Boiler FAQs, answered by experts

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.
