Lakeside Heating staff and installers were always professional and courteous. They went out of their way to explain every detail to us. After installation, the installers walked us through all the steps on how to change the filter and how to work the electronic thermostat. I was very impressed by Lakeside. The office staff associate, Holly- was always friendly and returned my calls or concerns in a timely manner. The office staff also helped us with getting our rebates and warranty paperwork. They were great and I am definitely referring them business in the future. As for Lennox products themselves, their reputation as a strong quality product has always stood out to me. The fact that I chose Lennox products was a no brainer to me. My family has always had Lennox air conditioning and furnace equipment.
