"We have an old furnace which is working very well and we did not need a repair but we usually have 1 or 2 tuneups every year. Every time we have a technician for tune up he tell us it would be a good idea to get a new furnace. The good part about LLC Heating & Air Condition was that they examine the furnace and thought it was in good shape and did not mention replacement . The visit was short and pleasant."

"The owner, Chad Adams, came out to provide me an estimate.  He fully reviewed my options, the costs, and the details of each option.  There was no pressure, just informative.  Great guy.
I decided on 7/22 to get one of the options and told Chad.  He scheduled me same day, which was a pleasant surprise. 
The team arrived about 10 and were fully completed around 3.  The installation went well, they cleaned up fully and we'd never know they were there.    The new system is great.
Overall great experience, and I will continue to use American Air for my system.

"The contractor performed an outstanding installation. The first visit, he assessed the work to perform, then walk me through the process he would perform. He offered various units to accommodate my requirement before I decided on the best option. On the day of the installation, he arrived on time, took the necessary safety precautions, did the installation and then walk me through the process of what he performed and showed me the operations. His quality of work (A+) and the cost (A+) met our expectations."

Install Boiler FAQs, answered by experts

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

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.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.
