When we were suddenly having issues with our heat last Saturday morning (of course when we had a houseful of company staying with us!), my husband called Lenz Heating and Cooling. Scott arrived within two hours and quickly diagnosed the problem – that the filter simply needed to be replaced! Our heat was back up and running in no time, and the best part: Scott didn’t charge us for the service call! We will certainly turn to Lenz with all of our servicing and tune-up needs in the future. They have earned our trust that they will provide quality service for a reasonable price!
