"First started working with Joe getting a quote got 2 bids which the other was cheaper, but decided to get ranger since Mitsubishi is the “top line” he said which I googled and saw it too. We talked that he will put the drainage on the car port and the vent on the side of the house. So when the date of installment came Daniel was on time and he introduce himself. I let him do his job while I was doing my own with my 3yrs and 5 yrs kids. The job was quick so when I check outside I saw that the vent was mounted on my carport. So I called Joe and ask why it was mounted on my carport he said it was in the contract which I didn’t see on the instruction. And so I have to pay if we move it. I was so disappointed! Now I can’t close my carport if I want to get a garage since vent is there. So I have no choice if only Daniel check with me first right from the start what the plan is then there will be no problem! Well the job was done got no choice. Another thing Daniel have to come back two times to fix the drainage since it keeps on leaking my carport. It was finally fixed on the 3rd time when Jared was the tech that fix it. It was so disappointing and I regret that I chose ranger cooking and heating!"

"Kelly Chong was great! He took the time to explain everything to us and his installers were friendly and polite. When they entered the house, they would always take off their shoes and kept everything clean. They even swept the garage when they were finished. Kelly provided exceptional customer service and even came out the following week to make sure everything was good and explain the new thermostat to my wife.

"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."

"I had an excellent experience with Jose Plumbing Excellence Northwest. They first helped me fix a leak, and later replaced my water heater when it went out. Both times, they were able to schedule me right away, which I really appreciated. The team was professional, efficient, and made sure everything was done correctly. Their customer service was great from start to finish, and they made the whole process smooth and stress-free. I highly recommend them for any plumbing needs!"

"Aaron Charles was our technician. He quickly diagnosed the condition as a faulty circuit board, called to have a co-worker bring a new one and got the furnace running like new. We were so impressed by how quickly he diagnosed the problem and corrected it. We will certainly use Mercurio's (and, hopefully, Aaron's) services again."

"Starting with the sales process, Nate was informative and great. Could've sold me a more expensive replacement system, but instead identifies how my current system cod be retrofitted with a heat pump. That sold me on G&S right there. Everything from the initial install review, the office staff working with my lender, to Izaak and the install and electrical teams, was punctual, informative and professional. I've had several bad experiences with other contractors, but I would confidently recommend G&S for any job and plan to use them again for a generator switch install. Good people with a good business. Thank you G&S!"

Install Boiler FAQs, answered by experts

You can replace baseboard heaters with many other types of HVAC systems, including forced-air furnaces, hydronic heating, and heat pumps. Each one has its advantages and disadvantages, so the best choice for you will depend on your budget, preferences, and the design of your house. If you aren’t sure which option is right for you, ask an HVAC pro for guidance.

Costs range from $3,000 to $7,500, depending on system size and efficiency.

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

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.
