No such thing as 0% interest

When it comes to financing HVAC units, getting a 0% interest loan isn’t really a thing. Here’s why: The contractor pays some interest upfront to the finance company, but they makeup for it by adding a hidden “dealer fee” to their prices. Once the project is done, and it is time for the finance company to pay the contractor, they deduct that extra “dealer fee” from the payment and cover the remaining interest on the loan. We don’t have any hidden “dealer fees” in our finance options because we think it’s not fair to you, our customer. We believe in keeping things straightforward and honest, without any hidden costs.

How to get the best interest rates

When seeking a loan for an HVAC system, choosing to work with a bank is often the wisest choice due to their generally favorable interest rates. Banks offer competitive rates compared to other lending institutions, making them an attractive option for financing major home improvements like HVAC installations. The stability and reputation of banks along with their ability to add collateral to the loan contribute to their availability for lower interest rates, resulting in potential cost savings. Additionally, banks may offer a variety of loan terms to suit different financial needs. While other financing options exist, the reliability and potentially lower financial burden make banks a preferred choice for securing a loan to enhance your home’s comfort with a new HVAC system.
