"I have used the company many times. Two technicians came out for the tuneup and completed the job in about 2 hours. The company has also replaced the furnace and AC in the past. They are very thorough and professional. The staff is also very friendly and available for service. I am a member of their club which makes them easily accessible to me."

"American Appliance Service was wonderful - extremely responsive, communicative, on-time, polite, knowledgeable, etc. Highly recommend. Our serviceman was Vic (I think he's the owner) and he installed a new ice maker in our Samsung refrigerator and installed a new lower heating element in our KitchenAid oven."

"I would recommend this company to everyone. Loved they are a small local, family owned business. Our furnace-boiler went out on a Saturday, Monday morning they were out and a quote in the afternoon. They made sure we had heat before Thanksgiving day. Very professional, knowledgeable, great craftsmanship. Best price on comparable equipment out of 3 quotes. Thank you!!"

"I had an excellent experience with Scott! Very friendly and extremely knowledgeable. During the thermostat installation procedure he discovered two issues with my AC unit (one of the fuses was blown and also one of the wires was fried) and fixed both without any additional cost. Very happy with the service and will definitely be using them in future. Thanks Scott!"

Install Boiler FAQs, answered by experts

Costs depend on issue severity, parts needed, and labor rates.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

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

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.

One of the easiest ways to determine which type of furnace will work best for your home is to contact a professional in your area. Many HVAC companies offer free consultations to help potential customers determine if they need a new system and which type would work best for their home and the community’s climate.
