"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!"

"We had a problem that water was mild warm when taking shower on our second floor, even though we turned the switch to the hottest. The first floor water did not get hot either. We first called Heritage yesterday since they installed a new boiler for us 3.5 years ago. Heritage technician came in and checked yesterday and gave us a list of parts to be replaced. The total cost would be more than $1300! We did not have them fixed, but still Heritage charged us $99.
Today we called Joyce Cooling & Heating, Inc. Joyce came in around noon time and identified the problem right away. He used his mighty tool and fixed the problem in several minutes. Now hot water comes out as we need. Amazingly, it only cost us $79.99! Joyce saved us thousands of dollars!! We are so appreciated his honest and quality work! In fact, this is our 2nd time using Joyce Cooling and heating Inc. Last time we had a problem with air-conditioning. He also fixed the problem and charged a very fair price. 
I would definitely recommend Joyce Cooling and Heating Inc. to my friends.

"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."

"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

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

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.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.
