"Initially, working with Universe went very well when we replaced a central air unit and installed a single-head and triple-head ductless unit... for about 1 season. After that, numerous issues arose (under warranty) from full line-replacement on the ductless units to having to come back to repair a wired connection that was reversed. This caused the AC to not work and have lots of moisture leak through our units. Additionally, pretty much EVERY season we have had an issue with our "brand new efficient systems" not working or failing. We leveraged the warranty and figured all the "kinks" of the installation were worked out over the first few years. Now, with the warranty expired for a year, we have had to have them back to our house several times with a service charge with absolutely zero consideration for the large project we have done with them and our dedicated customer history. We paid for those, thinking we would be done with repairs, as the tech said... Two days ago, with one single-head unit not powering up, they wanted to charge $285 just to show up to take a look at the issue... couldn't even send someone over when convenient to take a quick look... Severely disappointed in this "family business" that treats loyal/dedicated customers as a number. Their installation of ductless systems seems mediocre at best."

Varsity’s mission has always been clear: to serve our neighbors with integrity, solve home service challenges with innovative solutions, and provide lasting results. Our dedicated crew is background-checked, rigorously trained in the latest technology, and excited to exceed your expectations.

"Efficient and clear process, nice crew, quick and clean execution. It would score 4.5 as there were a couple of opportunities for improvement identified (including surprising problems with running a communication cable, and a trivial unnoticed misconnection sorted out the next day by a dedicated technical help call), but overall an outstanding service."

Install Boiler questions, answered by experts

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.

You save money on heating oil in a few ways:

  • Make sure your home is well insulated and sealed against drafts and heat leakage.

  • Use a thermostat that’s working properly and calibrated accurately.

  • Increase energy efficiency by insulating your basement and attic.

  • Turn down your thermostat a few degrees.

  • Program your thermostat to lower the heat when you’re not home.

  • Order heating oil during the off-season when prices are likely to be lower.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Each has its pros and cons, but hydronic heaters typically cost less to use than electric heaters, and they’re slightly more efficient than electric options. On the other hand, a hydronic heater usually takes a bit longer to heat up a room than an electric heater. The “better” choice depends on your needs and budget.

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.
