"Received 4 quotes. Cummings was the least expensive that I used to bargain two others to. They matched but had install dates of 30 days. Cummings had their electricians and HVAC guys here in 8 days. Installation done in 4 hours. All had good customer service & tech skills."

"Jane's replaced my 20-year old Munchkin boiler with a super efficient, modern Rinnai. Everyone was a joy to deal with. Service was excellent. Darian, who scheduled and arranged the replacement, and Greg and Oscar (who did the work) were fantastic. Excellent service, especially since I live on Lopez Island, which is not easy to get to. Competent, good-natured, hard-working, nice folks."

"Chris J. was so professional, efficient and friendly. He answered all my questions and explained a lot of things that I was unsure about. He also went the extra mile to let me know of a filter that could help my family with health issues. There was no pressure, just clear information. I did some research and confirmed that the filter would be helpful for us. So Chris installed one the same day, after several hours of the tasks he had originally come to perform. The weather was hot, but it did not slow him down and he did not complain. A friendly, competent guy. That has bee a typical experience with WES folks over several decades. They seem to find good people and train them well. Great Company."

"Simon was very professional - he showed me pictures of interiors of the ducts and explained to me exactly what needs to be done and what doesn't need to be done. I ended up finding out that the fan inside the furnace had so much dust in it, even though a different company is supposed to have cleaned it up last year."

"Excellent. Greg was timely and professional. I showed him what I wanted to do outside at the greenhouse. The next step was to look at the electrical panel for the home to determine what was required to move the power. At that time, Greg noticed that I had outmoded controls on the three baseboard heaters in the downstairs rooms and recommended they be replaced (they were over 30 years old) and he replaced them. Outside at the greenhouse he moved power into the greenhouse. We also discussed a future visit to replace the original electrical panel (the home was built in 1964)."

Install Boiler FAQs, answered by experts

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

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.

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model.
