"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

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

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.
