Advantages of Buying a New NTI Boiler Over Renting
Buying a new NTI boiler has many advantages when compared to leasing. For example, you can purchase a new model that provides increased energy efficiency and has a lower environmental impact. New units are also more reliable and have better performance.
Another benefit is that it can save you money in the long term since you don’t have to pay for its rent. It also gives you more possibilities for customization and increases the value of your property.
At our company, we can help you with the necessary documents to receive a state rebate should you buy a boiler from us. The sum of the discount depends on your income, place of residence and the state aid you have received previously.

Professional and FastWe’ve been having issues with our thermostat, so I called Superior HVAC Service. Liam arrived on time, diagnosed the problem right away, and had it fixed in under an hour. He was professional, friendly, and even took a moment to check the entire system to make sure everything was in working order. Highly recommend!
