"Williams & Associates replaced an ancient, very large old boiler in my very large house. Bruce calculated the necessary size and found a suitable boiler. He and his crew thoroughly cleared the radiators and lines before removing the old boiler and installing the new one. They checked all the radiators and added new valves as needed during a lengthy checkout. It took several days to do all the work. Throughout, Bruce explained what they were doing and why as well as recommending changes/additions to the original proposal. They were even cheerful about removing the original "Mary Jane" from the basement. I would definitely recommend them to anyone using steam heat. Great job!"

"I really enjoyed having the work done by East Coast. They were professional, and when I had questions, they took the time to answer them, even if it meant calling in someone else, or coming by on another day to demonstrate some of the features of the system. In my book, East Coast goes above and beyond the contract to really provide customer satisfaction."

Install Boiler questions, answered by experts

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

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.
