"I requested help on Angi on Wednesday and was set up with a Friday appointment. Received a call from Old Skool telling me they could come to my house on Wednesday. Frank came to the house, diagnosed the issue, didn't try to upsell me with things I didn't need. He told me he thought he could have a new AC unit to install on Friday and they are here, on Friday, installing my new AC unit. Everyone at Old Skool is professional and courteous. The price was competitive and not only will I use Old Skool again, but I will recommend them to others. You won't go wrong with Old Skool!"

"I can't say enough about the team at Old Skool HVAC. I learned of this organization from a close friend who had work done and recommended them. Frank is a great guy. On time, professional, knowledgeable, and his team is a reflection of this as well. They were always on time, on schedule, clean, and very personable. They finished our job a little early, and during the first heat wave just about week or two ago, our house never felt better. Great service, quality, and pricing. It's funny, with central AC, you never really know that it's hot out until you leave the house and come home. It's during this first transition that I realized how quiet and effective of a system that was installed. If you are looking for any form of HVAC work in your home of business, I'd recommend contacting this group of professionals."

"HVAC Gurus were amazing. Extremely flexible in work with and around other trades also busy on the complete renovation. Their technician Joe did such a good job; he designed and planned the HVAC retro-fit of central heat and air into my 100 year old house to be transparent. Then Joe did the work and delivered flawlessly. Great value for money, below other bids I got. Iâ m in the trades and Iâ m telling you, these guys are top notch."

"After buying a new refrigerator, Home Depot told me I needed a plumber to run a new water line to the refrigerator. I was not happy with the Home Depot tech that called me. The plumber, Dave, arrived soon after I called Harris and did a phenomenal job! He was friendly, professional and worked quickly. Thank you, Dave, and Harris Plumbing!!"

Install Boiler questions, answered by experts

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.
