"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."

"We had a leaking 35 year old oil-fired boiler that needed to be replaced. This was just at the start of the heating season in 2021. We got quotes for price & installation dates from several HVAC companies Clear All HVAC supplied several boiler replacement options and also quoted an earlier delivery date than any other quote. We selected a boiler/indirect water heater combination that was significantly less than competing quotes. Clear All installed the system within a week and responded quickly to any concerns & questions we had. We highly recommend Clear All HVAC for anyone that needs HVAC installations, repairs, service and values good customer service. In our opinion they are outstanding and we will continue to use them as our go to HVAC Services company."

"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."

"Applied for 0% Mass Save heat loan with Addarioâ s Services, and now have a Bosch Bova1.0, 18 Seer heat pump installed today 2-19-21. The only slight glitch was waiting for two parts to modify my old Thermo Pride oil furnace to make it work correctly. I highly recommend Addarioâ s Services for a prompts accurate estimate, installation, and very friendly customer service."

Install Boiler questions, answered by experts

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

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.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.
