"Repairs were excellent and thorough "even well documented". The tech found units low on coolant. He identified and repaired multiple refrigerant leak points. I have dealt with many HVAC contractors over the years and Freedom Air Mechanical is one of the best. I highly recommend."

"Sunrise Heating and Cooling did an excellent job installing my new Rinnai tankless water heater/boiler. From start to finish, the experience was smooth and professional. The crew was knowledgeable, punctual, and took the time to explain the system and answer all of my questions. The installation was clean, efficient, and clearly done with attention to detail. Everything works perfectly, and I couldn?t be happier with the upgrade. It?s clear they take pride in their work. If you?re looking for reliable, honest, and high-quality service, I highly recommend Sunrise Heating and Cooling."

"My boiler in Wolfeboro NH failed suddenly. It was old and needed to be replaced anyway but I was hoping to get another season out of it. I called quite a few boiler companies and had difficulty even getting someone to answer the phone. Then I lucked out. I called Ed Grant and he answered his phone. It was November and getting cold. He came out to the house promptly and very professionally installed my new boiler. Not only is this guy honest, straight forward but he is such a hard worker. He worked diligently until the job was up and done. Absolutely no headaches, no bullshit, and not a salesman whatsoever. Ed Grant is the REAL deal if you need a new heating system. I would hire him again in an instant without a worry. A+. Thanks, Ed Brian Whitehouse"

"Tyler was extremely helpful and accommodating and helped me on very short notice with 2 plumbing projects recently, even spending almost an entire Saturday working when a washing machine install ended up being more work than expected. He is professional and extremely reasonably priced. Will definitely recommend and use for all of my plumbing needs."

"It was a little bit confusing for me. I purchased this coupon and this company then charged me another hundred dollars on top of it. It was a little bit difficult for me to look through what I already paid for and what was extra but that wasn't very communicated. That was very confusing as well as not a very good experience. The fellow was friendly. It wasn't very clearly communicated what I had already purchased for with this coupon. They did some work on the ducts here but because of this, it kind of made it a little bit of bad experience but overall, it's an average rating. They should communicate better to me to begin with before they actually show up what was purchased and what additional services that I can buy."

"Work with Tylor. His quality and customer responsiveness is top notch. I had him install 3 mini splits in our home. I originally wanted Mr Cool.. He coached me into upgrading to Mitsubishi for our area due to it’s significant quality increases vs Mr Cool and he was able to purchase and install faster and significantly cheaper than the “Home Depot” “Mr Cool” 3rd party install pricing company Highly recommend Tylor and his work"

Install Boiler questions, answered by experts

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

Propane is more cost-efficient than natural gas on a per-unit basis because it produces twice as much heat energy as an equivalent amount of natural gas. But propane is not ideal if you already have a gas line installed. The best choice for your home depends on the efficiency of your appliances and the amount of installation required of your fuel choice.

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.
