"Ken Marcus, the technician who performed the work, was highly professional and courteous. He completed the work in the time frame promised, including the recommendation and installation of a germicidal unit inside the air handler. Ken indicated that the germicidal unit was 99.9% effective in the killing and removal of mold, spores and bacteria from the A/C system. This would be of great help in the improvement of air quality inside the home, as well as prolong system life. Ken cleaned up thoroughly when the job was completed."

"Fontana Brothers installed my new Bosch HVAC system, and I couldn’t be happier with the experience. Freddie and Shaquille arrived exactly on time, worked efficiently, and left the work area cleaner than it was before they began. Their attention to detail and professionalism were outstanding. As a Realtor for more than 30 years, I’ve dealt with many HVAC companies, and Fontana Brothers continues to be one of the very best. They consistently deliver excellent service to both me and my clients, and their pricing remains highly competitive. I trust them completely with my referrals. Special thanks to Dan Fontana, who heads the service department — always organized, responsive, and helpful — as well as the entire office staff, who are consistently friendly and a pleasure to work with. I will absolutely continue to recommend Fontana Brothers to others seeking HVAC installation, repair, or replacement."

"Great installation Team. Professional, meticulous and very personable. They came on time and worked all day to replace my 18 year old system with a top of the line highly efficient system. They cleaned up everything and left it spotless. They even vacuumed the small amount of dust they made installing new thermostat in house. I am nosy with these kind of things. They answered every question politely and thoroughly when I asked them. During the installation, every time I went to see how things were going, they were hard at work constantly. I HIGHLY recommend Ierna."

"Dan and Tim are a super team.  They investigated, quoted, ordered, delivered and installed the water system which turned our well water in to holi-water.  Love their sense of humor, and their way of doing their job, and at the end of the day I am very happy.

"Steve showed up and first filled the unit with nitrogen to see if the leak could be located that way. Since the leak was so small and was located under some line insulation it was not evident. Step 2 was to vacuum out Nitrogen and replace with Freon and dye. We ran the unit for 24 hours and then Steve came back the following day and found the leak from the dye. He then had to repair the hole and then refill the system with coolant again after another deep vacuum.  
All in all he was very professional and he told me from the very beginning how much the cost would be and stuck to that exact price to the penny. Steve is definitely one of the most honest tradesmen in the business and I will definitely be using him again when it comes time to replace my ageing AC unit.

"Plumber was prompt and arrived when scheduled.  He unclogged my bathroom pool toilet.  He then gave me a price for the installation of a laundry tub.  He came the next day and neatly broke through the garage wall to get to the pipes to be able to install  the laundry tub.  This precise cutting of the sheetrock made it possible for my husband to reinstall it  without any problem.  I would recommend this company and will use them again."

Install Boiler FAQs, answered by experts

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

Heat pumps are significantly more efficient than boilers, typically providing three to four times the amount of heat for the electricity they consume. While boilers run on fossil fuels, heat pumps use only electricity. This efficiency can lead to long-term savings on operating and maintenance costs. However, heat pumps have a higher upfront installation price compared to boilers. Despite their lower efficiency, boilers remain a popular choice for many homeowners, with 8 million in the United States alone, due to their lower initial cost and less intensive installation process. Ultimately, the best choice depends on your home's infrastructure, your budget, and your personal heating priorities.
