"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

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.

Costs depend on issue severity, parts needed, and labor rates.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

Propane is more cost-efficient than natural gas on a per-unit basis because it produces twice as much heat energy as an equivalent amount of natural gas. But propane is not ideal if you already have a gas line installed. The best choice for your home depends on the efficiency of your appliances and the amount of installation required of your fuel choice.

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