"It went very well! Dylan was knowledgeable about removing our old oil burner that had died, and installing the new heat pump unit! The work was done in a timely fashion and he removed the old heater and cleaned up everything from the new install. He also followed up after a few days to make sure everything was okay, which it was. I would recommend Venture Mechanical to anyone of my friends, and will use them in the future for routine servicing on the system and for any other HVAC needs I may have!"

"We installed a Fujitsu mini-split A/C and heat pump because installing duct work was not an option. The entire process from getting a quote to completing the installation couldn't have been any better. Joe went over the full scope of the project including the ramifications if any additional work was needed. I don't think one could find a better HVAC company than Airco!"

"It was quite a surprise to find black mold growing in our mini-split heat-pump/ac units over the weekend! The situation was quite dire with the system emitting a bad smell and the fact that I have asthma and mold allergies which posed a serious health risk! After being told by the company that originally installed the system, “We don’t provide deep cleaning service for these units, try looking on Angie’s List (boo on Sila!)” I landed here. While other companies did respond to my bid, Atlantic Heating and Air Conditioning was the most responsive and was able to send out a team on one day’s notice (the wait for other service providers was up to three weeks!). The tech team, Josh and Zack, arrived on time and called me 1/2 before arrival as promised. They were very respectful, kept a clean work space and (since we are in the middle of a pandemic) wore masks and were very careful about the usual COVID protocols. The four units in our home are now SPARKLING CLEAN! We are 110% pleased with this job!! We will hire Atlantic as need be in the future for our heating and cooling needs. I have given up on the company that originally installed the units and will post a truthful review about them in an appropriate space online. I would definitely recommend Atlantic to family and friends. (photos attached to this review show one of the units before cleaning - did not think to take after pictures. Suffice it to say, no more mold:)"

"I appreciated being able to speak with someone in the office to explain my situation (leaking water heater), and having someone come to my home so quickly to go over my options for dealing with the problem. Dylan, Aaron and the entire crew were so professional and knowledgeable about the on-demand hot water system we chose to install. They were a pleasure to work with, and I would highly recommend them to friends in need of similar services."

"The sales team and installers were professional and responsive. I had contacted other companies for quotes. Peter and team came right away and were considerate of my home and health. The others were not. When looking at my home they gave me the options needed for our unusual configuration and home history. They wore PPE and were meticulous . So happy to have a climate controlled home!!! If that is what you want call Majic!"

Install Boiler FAQs, answered by experts

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

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 way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

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.

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.
