"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

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

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.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.
