"Fontana Brothers Heating and Air Conditioning installed a new 3 ton AC unit for me and did an excellent job. I had a freon/leak issue with the old unit and during the installation they went above and beyond to ensure that anything impacted from the leak was cleaned up, corrected, and properly insulated before installing the new unit. Pedro, Luis, Dan and Andre were very professional and kept me informed throughout the process. I would definitely recommend them."

"Larry came and gave a second opinion to see if my daughter actually needed a u/v light installed for about$900 + so I called Larry from Angie"s List.He said no we do not really need one ,just a regular cleaning as some accumulation is normal.But he said his price would be $385 if it was needed. in the future.Larry is the owner and has no desire to up sell customers .This was my first experience with Larry and I am pleased with him being up front for not trying to sell me something we do not actually need..His good reputation is important to him and his reviews all see Larry as an honest professional.I would recommend Larry for a second opinion if you are ever in doubt as I was with the other company.."

"Travis and his installation/service team did a fantastic job.  After determining that my 13 year old AC/Heating unit could not be repaired, Travis worked with me in explaining in detail the different options available for replacing the current system.  He gave me a great price for the unit I selected and the installation went flawlessly.  He and his team were punctual, polite and very professional.  I highly recommend this company.

Install Boiler FAQs, answered by experts

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

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.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.
