Pleased with technician and service, and will do business again them again if needed. Owner called to confirm service and sent a text with name and information about the technician before his arrival."

"ALâ s Heating & Cooling did a perfect install for us of a tankless water heater from start to finish. They were quick to respond to any questions and requests for quotes, were very professional throughout the install, and saved us a good bit of money over what competitors were asking. Would highly recommend."

"The boiler had needed some replacement pipes as well as the solution to the slight smell of gas when near the boiler itself. Prior to calling for service for these issues, I had removed the majority of the damaged piping and purchased all new of what I was able to remove. I couldn't remove the bushing that attaches directly to the boiler or the nipple that attached to that bushing to save my life. On the night prior to the day of my appointment, there was a snow storm and time moved ahead. I had forgotten to move my clocks ahead that resulted in my arriving about 20 minutes late. The repairman was kind enough to not only wait for my arrival, but to shovel part of the snow from my walkway that leads to the basement. This guy is just great. He removed the fused together bushing and nipple in no time flat. It was amazing for me to watch. I had to pick up a couple more pieces of pipe for my job to be completed and we scheduled to continue after I did so. Luckily, The pipe I needed was in stock and he was able to return the very next day, he removed my bushing and nipple, installed ALL of my pipes, and provided and replaced my leaking gas line. MY BUILDING NOW HAS HEAT AND I COULDN'T BE HAPPIER!!! Now I have to have the other parts of the building repaired that were damaged from when the boiler had stopped working and a pipe had burst. You won't be disappointed if you hire Discovery Heating and Cooling. If I have another related job in the future, I will definitely call Discovery. Thanks again Discovery."

"Jose was outstanding. He was very thorough in his approach and talked through all the options and considerations with us in advance of installing two of our TVs on wall mounts. He first came to do an assessment to get a better sense of what the job would entail and then quoted us a fair price. The job ended up taking longer than the initially quoted time, but he held true to the quoted price. He sent us pictures at various stages to ensure we were happy with the result. Would highly recommend Jose for TV mounting and other jobs."

"On the coldest day of the year, my furnace, as expected, decided to stop working. Having just bought my home, I was faced with a tough decision?repair the old system or invest in a new one with a 10-year warranty. After speaking with Astera Heating, Cooling & Appliance Repair, I knew I was in good hands. From the very first call, Valentina was incredibly sweet and quickly scheduled an appointment for the same day. Steve arrived promptly, diagnosed the issue, and found that the motor needed replacement. After discussing options, I decided to go with a full furnace replacement instead. The very next day, Steve and Yuriy arrived and installed a brand-new system in just four hours! Now, my home is warm again, and my new furnace is incredibly quiet compared to the old, noisy one. I couldn?t be happier with the fast, professional, and high-quality service that Astera provided. If anything happens in the future with my AC or appliances, I won?t hesitate to call them again. If you need rel"

Install Boiler FAQs, answered by experts

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.
