"We were extremely happy with our entire experience. Grove responded quickly to our inquiry - provided a quote the next day and started the day after that. Our attic air handler was very difficult to access and Grove had a "can do" attitude about the entire installation. The price was comparable to other bids - but for a better system and with a much better explanation. They were on time, complete, and clean. We will absolutely use them again."

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

"I had a leak somewhere in my heat pump system from 2013 in a 4 floor condo building. Every other company was quoting me $7k+ to replace the system but it turns out to be a leak in the line set between the 3rd floor and the roof! We had a new line set installed and I spent $2550 in total! The crew was very professional and worked extremely had in the hottest weather to get the job done, too!"

"We hired Sucoy Company to install a heat pump in a new ADU. Although the work is still in progress, Justin was very easy to communicate with and very helpful in providing information. We subsequently hired them to change the thermostats in our main house, and John did a great job. He was friendly, easy to communicate with, and on time. The first time he came out, it turned out that one of the new thermostats was defective, and he did a good job troubleshooting to pinpoint the problem, and then came back another day to install a new thermostat."

Install Boiler questions, answered by experts

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

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 radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.
