"Beware of shipping issues with this company. Ordered an ice maker installation kit on 10/10/25. Shipping was due no later than 10/20 according to company and FedEx tracking. FedEx tracking showed the package at their facility for 8 days without moving beginning on 10/15. Called FedEx 3 times. Each time they said they cannot find package and I have to contact shipper. Shipper has to make a claim, they will not mark it as lost. Called Appliance Parts Pros twice. Each time they say FedEx has to mark package lost before they will do anything. They also state they have to wait 14 days from them before doing anything because of their contract with FedEx. I don't care about their contract, I want what was ordered and paid for.

We are proud to be northwestern New York's authorized Basement Systems Premier Dealer. All of our warranties are backed by Basement Systems. Contact us today for your free estimate!

"The project went very smooth. Tim was the only one that brought up points that other contractors did not. 1. The window I already had was too close to an electric panel. Most contractors want to charge a lot extra to block it in to move new egress window over. Tim did not and said it would not be a big deal. 2. Had many good reasons why I should go with a slider for my particular situation. 3. Estimate received did not just had a price but listed the work to be done properly. Too many contractors skip the details. 4. One of the only contractors that would dig all the way to the footing. Most just dig a hole with a post hole digger for the drain and cut corners. The project had to be rescheduled a couple times but that all was smooth. Brandon, John and crew arrived on the start date and you could tell right away they had a smooth process for installing egress windows. No damage to the lawn because they lay boards down to protect it. Brandon addressed my concerns about the drain and after discussing with him I felt much more comfortable having a better understanding of it. Great communication. They were neat and tidy in the house. I had no idea what to expect having a hole cut in my foundation wall. However, it was suprisingly not that messy. All flashing details with the window were done properly. No complaints I would hire again. In a few years I will be calling about my garage floor."

Heating and Air Conditioning questions, answered by experts

No, not all HVAC systems have a fresh air intake, but there are many advantages to having one. For example, a fresh air intake can boost the air quality inside your home and help your furnace run more effectively. Plus, it can make your house more energy efficient, possibly saving you money on your utility costs.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.
