We've been customers with Lartz Heating and Air for about 4 years now and they have always provided us with good service. Some guys that they send out are better than others but overall they are very consistent in the high level of customer service they provide us. My father was with them for multiple years before me as well and they did very good work for him as well. They have done general maintenance for me and also an A/C unit installation, which has all worked out very well. We have never had any issues with the work they have done and will continue to use them if we have any other heating or cooling needs.
