"Within 5 minutes after Roy walked in, I knew I was speaking with an expert. He talked me out of wasting money on what I wanted (getting rid of boiler and replying on furnace) telling me about how everyone in the city during -40 degree nights was will freeze and if I keep the boiler I'll be comfy. He also talked me out of choosing a heat pump, saying in Chicago it will cause problems in the dead of winter and then I'll be out of luck. Initial estimate was only to replace the 60 year oil leaky boiler and 40 year old loud AC and furnace. Came in, did the work quickly, and when we were doing final inspection he pointed out where my last remaining original furnace was having problems. Gave me a great price to just get the the last furnace and AC done (AC was 40 years old). I know they won't be the cheapest but if you want someone you can trust who will guide you with his 30 years of experience and teach you the finer details of heating and cooling while delivering quality work, go with Porterhouse. I won't trust anyone else."

"An honest, excellent overall experience.  The technician was on time, did a thorough inspection/cleaning and answered any questions I had.  He accidentally broke a small part, immediately notified me, and replaced it on the spot after obtaining a replacement.  He did not try to upsell or otherwise attempt to get me to buy anything else.  A lot of companies use this opportunity to try and sell you a new furnace/A.C. even though you may not need it.  An impressive experience and I will definitely use this company in the future.

"We called them in to do a tune-up on our furnace before winter. Of course, the service guy found cracks in our heat exchanger and told us we needed a new furnace (although the furnace was over 20 years old). We agreed that we needed to replace the exisitng unit, agrred on a price, signed the contract, and scheduled a date. Installation was on-time and went very smoothly. Technicians were very professional and cleaned up afterthemselves. I would highly recommend."

Install Boiler FAQs, 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.

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.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.
