Our water heater had stopped working. We called Seider Heating and they were at our place within a. hour, and fixed the heater in 30 minutes. Since our unit was within warranty, we were not charged anything. We were really happy with the service. Service: Electrical panel replacement or upgrading

Installed in attic central air unit in March 2020 in an almost 100 year old home with no vents. There were some tech issues with the wall thermostat that they came back and resolved quickly (due to not using it for heating and just the cooling), otherwise the house has been comfortable for summer 2020 and 2021 as well. Wanted to wait over a year before leaving a review to provide a longer experience example.

Great price, service and installation. Jason and Allex were here to install a 75 gal. water heater. They arrived first thing at 730 this morning and wrapped things up by 945. They were very professional and left the job site very clean. Totally loyal to Seider after they helped me previously getting a new furnace installed on New Year's Eve. Outstanding company.

I contracted with Seider to replace my old hot water heater and to replace a very old wash tub basin in my laundry area. All I can say was the work that was performed was AMAZING! I found them to be very reasonably priced, great work by Nathan my plumber with a suggestion to make it work much better. Super professional and friendly. Not always easy when trying to work with a contractor you are putting your faith into to do a good job. Thank you Seider!

Seider installed an AC unit in our home and has serviced it since its installation. I called today for service and was told they do not service our location. The phone operator (Amy) was rude, less-than-helpful, and either hung up on me (twice), doesn't know how to transfer a phone call, or their phone service is not working properly. She seemed put out that I was calling first thing in the morning.

Nobody can find a record of our business, but I have a cancelled check and paperwork showing purchase and installation of AC unit. There are plenty of other HVAC providers. Even if I receive a call from the general manager, we'll be taking our business elsewhere.
