"Very pleased working with Adams Heating and Cooling. They installed a new central air conditioner system from Rheem. Everyone I spoke with from Amber and Gene in the office, Terry in Sales, and Joey R and Alvin with the installation were friendly and professional."

"Everything was wonderful from start to finish. Norman and his staff were attentive and friendly throughout the whole process. We were given a quote and then took some time to get other quotes and secure financing. When we were finally ready to commit we let WTPI know and they had our furnace installed within a week! A few days later when the system needed to be balanced Norman was out that afternoon to get everything set up. He is very knowledgeable and made the whole process very comfortable and enjoyable. He explained everything very well and even invited us down to check things out every step of the way. I highly recommend WTPI for any job big or small. We will definitely use them again!"

"/the owner came on the same day I called, assessed what needed to be done, set a date for the work to be done, told me what I needed to purchase (a new motion sensor outdoor lantern) and did not charge for the visit or the estimate  Today they arrived on time and  efficiently fixed everything in an hour and a half.  They installed the outside light in the freezing rain and laughed at my worries for their welfare, even though they got soaked standing on a ladder.  They were polite and efficient and I would recommend them to any one needing electric work done.  Very nice people and a pleasure to work with.

Install Boiler questions, answered by experts

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out

Most installations take 2-5 days, including old system removal and setup.

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.

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.

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.
