Thank you Van Genderen We had out of town company this weekend, and the air conditioning went out. We called Van Genderen and with in one hour they had a tech at our home. A full replacement was needed, a major project. Two hours later they had the new air conditioning unit and 3 techs working on the new install. At days end we had a cool home for our guest. The first call to the office was professional and kind, with results. The 3 techs were all experience, friendly and kept us updated. We are grateful

I needed to have my A/C unit serviced for the upcoming spring warm weather. I called my previous service company and was told they had no open A/C service calls open until mid to late May! They recommended Van Genderen. I called in the AM and was able to get a service call scheduled for that same afternoon!!!! The service technician that arrived was Ryan and I can't say enough about his knowledge, patience in explaining what he had found and recommending what he thought was necessary. I would definitely recommend this company and technician, Ryan, for any A/C service you might need before the really warm/hot weather.

Ryan was amazing. We needed service on a Friday night, and Van Genderen had the highest ratings. A small family business since 1946, & they were to our home within the hour, with all issues resolved (including going for parts) within 3 hours. Ryan was so professional, patient, and knowledgeable. We will be using this company ongoing for HVAC needs & can’t recommend highly enough. Thank you for everything, Ryan!

Called about my furnace in the middle of the day during the week, and they were able to be here within a half hour. Very prompt. The technician, Bob, provided top-notch service and was extremely respectful and knowledgeable. If I could give the Van Genderen company more stars I absolutely would! Thank you for your service and care. I absolutely recommend this company to anyone experiencing heating and air conditioning issues.
