"We needed our boiler replaced and had multiple companies come and look at the job. We ended up selecting Sila as we read good reviews on the company. Sila surpassed our expectations. The tech who performed the install (Gage) was on time, communicated the entire process to us from start to finish and did a tremendous job. He also made sure to clean up afterwards and was very professional. We would absolutely hire Sila again!"

"Joyce Cooling and Heating installed a new high-efficiency Lennox furnace and air conditioner. The installation looks great and was professionally completed. The furnace is working fantastic and is so quiet we can't even hear it running. We are warm and comfortable all the time and the new high-efficiency design should save us money for many years to come. The technicians answered all of my numerous questions."

"Brian at Clear All was recommended by a friend and they lived up to the recommendation and beyond. Helped trouble shoot a broken boiler for my in-laws and once he saw it he highly recommended replacing the boiler. I knew this was not an up-sell as the boiler was in very rough shape. While the new boiler was obviously more expensive then the repair, the price quoted for the boiler, burner, install, and removal of the old system was very fair - too good to pass up and risk throwing good money at bad with a repair on a 20+ year old boiler. Contacted them on a Monday, Brian showed up on that Wednesday to assess the situation and the new boiler was installed and running by 5 pm Thursday. He kept me in the loop through the whole process even though it was my in-laws boiler install. He also took the time to evaluate the size of the house and recommended a much smaller boiler - the existing one was way oversized and therefore over-using heating oil."

"Highly recommend Joe! 30 yr old boiler died, leaving us with no hot water. Joe quickly came and provided quote for boiler and new Indirect water tank which we wanted replaced. His price was a lot more reasonable than other quotes I got. also was able to get project done the same week as quote where others were scheduling 1 to 2 weeks out. despite the supply house delivering the boiler late ( Joe stayed in contact advising progress) He still was able to complete the work when he said he would. Top notch guy, Fair and honest. finished project looks great and works as advertised! Have more work for him to do"

"Scheduling was right on point. System was installed right after Christmas. Prep process was thorough. Extremely responsive when we switched over to A/C and performance wasn’t as expected. Was a factory setting issue. Very communicative amongst their team and with us. Great follow through. Proactive annual maintenance scheduling and thorough in their system review. Would definitely use them again."

"We had been considering replacement of our ancient, dust-collecting, rusty-looking, hot water radiators which heated our home well, but somewhat unevenly, in our 1929 Dutch Colonial. We also wanted to move away from window air conditioning units that had to be put in and taken out each season and finally move into the world of central air. I looked into conventional central a/c and heating and the quotes I got were more expensive or equal in price and because the required large ductwork would practically eliminate my already pathetic closet space and be much, much more invasive. So HVSD was definitely the only viable way for us to proceed, if at all. I remembered hearing about HVSD at a wedding years ago from my husband's colleague who had used Climate Technologies for installations in 2 different homes and he couldn't stop talking about how great it was. (Since then he's had it done in a 3rd home, too.) Fast forward to 2008 when I've finally saved enough money to consider having the work done. I asked my husband to get the name of this contractor and it was Don Martin at Climate Technologies. I contacted them in mid-April of 2008 and Steve Martin came out within a day or so. I signed a contract at the end of April and they came to do the job in early May 2008. Although I had good recommendation on which to base this decision, I was reluctant to do the whole house all at once, because I still worried about the potential for noise/loudness of the HVSD and if we would be happy, which is why I only contracted for the upper floor. I wanted a soup to nuts job (removal of my aforementioned humongous radiators, electrical, central heat and a/c, air filtration for my child with seasonal allergies, etc.). The work took a day or so longer than I thought it would, but that can be partly attributed to them not doing something invasive, which they avoided by thinking outside the box--in this particular case, running a drainage pipe so it would flow into my gutter, instead of a quicker, uglier solution. I did not submit this report earlier because although we used our a/c over the summer, I wanted to test my heat during the first winter, too, so I could give a thorough report. At the end of the summer I was satisfied enough to schedule Phase 2 (ground floor/lower level) for the fall. We are very happy with our HVSD heating and cooling system and the work performed by Climate Technologies."

Install Boiler questions, answered by experts

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

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.

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.

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.

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