"I was shocked at how inexpensive replacing both my air conditioner and heater was by getting them done at the same time and also with the pay by check discount. The order cost me much less than I thought it would so I upgraded to the middle option. They offered a new water heater for less than $200 more installation included. Wow. Everyone that I dealt with (phone / quote / installers were super friendly. I was afraid to choose a company for such an expensive purchase so I went with the one with the most personal recommendations. I'm so happy that I did."

"My air conditioner stopped working on Sunday. I found the coupon for a free diagnostic service and called them Monday morning at 7:30. They were polite on the phone and made an appointment for between 12:00 and 2:00 the same day. They showed up right around noon and quickly got to work. They listened to my description of the problem and were able to narrow it down to either a bad capacitor or bad fan motor. They quickly disassembled the unit to test the capacitor and motor to find a bad capacitor. They had the part on the truck and was able to immediately install a replacement. My air conditioning was operational by 1:00!"

Install Boiler FAQs, answered by experts

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.

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.

Deciding whether or not to replace radiators with a different heating system depends on your personal preferences. Radiators can take longer to heat up than a central heating system, and they take up floor space. However, they can be very efficient at heating, and they keep rooms at a more comfortable humidity level in the winter than forced-air systems.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.
