"There were several problems with the space pack AC unit AC Engineers installed in 2016. AC engineers really stands behind their work. Their technicians are excellent. It took several visits to restore my system but AC Engineers did the job right. I live in a 100 year old house and repairs to my boiler and AC and other systems are a fact of life. AC engineers is a pleasure to work with and I have no reservations to recommend them to a friend."

"Started with brand of furnace, asked what I had done to attempt to fix the problem.  (It was then that I realized how 'ignorant' I really am.)  She recommended I check the circuit breaker.  Never occurred to me to check since I had electricity on the first and second floors.  Got a bit suspicious when the stairwell light to the basement didn't come on.  So, I got a flashlight and checked the breaker.  Turned it off and then on again.  And ... low and behold, the furnace came on.  (guess who was Very Embarrassed)   We went on to chat a bit to make sure it was going to stay on.  She was very pleasant and understanding.  I inquired about replacing my furnace humidifier and she gave me information as well as cost.  A bit pricey, but I'm fairly confident I will call back and schedule to have them install one.

"So far so good; they are very knowledgeable. The guy who came over was for our service- because we had lost heat, was very honest, and showed us what the problem was. He was also knowledgeable about his product. When they came over on Monday, the installer was very knowledgeable; he took the time to talk to us for a good 30 minutes- he explained what would occur and I appreciate that because I like to know."

Install Boiler FAQs, answered by experts

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

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.

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.
