"We were very happy with American Family. Their bid was competitive and the installation of our new air conditioner went very smoothly. They removed the existing system and were great about not destroying our landscape. We had them install the new system in a new location, away from the back patio. So far everything seems to be running fine and I would happily recommend them to anyone."

"Phil came out to provide a free estimate for a new boiler. Appointment was scheduled for the same week and Phil called to move up the appointment due to a cancellation. He was very thorough, asked questions and answered all of mine. Would definitely recommend.

"Dan was incredibly helpful every step of the way. He broke our estimate down for us, separating the cost to just replace the boiler and to add a radiator to one of our rooms. He also had a plan to be able to do the projects separately, if we wanted. We ended up doing everything together. It was very quick, the techs were super polite and knowledgeable. Would HIGHLY recommend."

Install Boiler questions, answered by experts

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

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.
