"Frank and his team were awesome. Another contractor made a mess of installing a new boiler. I had one problem after another. It was a nightmare. Frank came in and gave me an honest assessment of what was wrong and what needed to be done to make it right. His price was fair and reasonable. He worked with my schedule and got the job done in two days. His team was very professional and friendly. It's always tricky when you have to hire one contractor to fix the work of a previous contractor but from the first meeting I knew OSH was the right choice. I only wish I had hired them first."

"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."

Customers say: Quick response

"Woke up with no heat! Right before Christmas! Harris responded instantly and sent out someone to check the problem. Due to incorrect installation, rain had gotten into the improperly sealed roof vents, which in turned fried the transformer, inducer and circuit board. They were at my place bright and early the next morning installing a brand new furnace, more efficient and quieter, with a 10 year warranty. Arranged financing and were finished by 3pm. Everyone from my first phone call to the last service tech was professional, polite, knowledgeable and all around pleasant and really nice people. They will be my go to for heating, AC, plumbing and electrical from here on in. Glad I found them!"

Install Boiler questions, answered by experts

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

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

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

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.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.
