A Dedication to Service
Report
You can get service when you need it because of our focus on service instead of the easier new construction. In order to make certain that we have technicians available to meet your service needs when you need them, Grenz Service Company, LLC focuses on repair services and replacing equipment that breaks down rather than spreading itself too thin and getting involved in new construction.
Selecting an HVAC Contractor
Report
Study up - Find out about license and insurance requirements for contractors in your state. And before you call a contractor, know the model of your current system and its maintenance history. Also, make note of any uncomfortable rooms. This will help potential contractors better understand your heating needs.

How BTUs and EERs Work
Report
Most air conditioners have their capacity rated in BTUs, or British Thermal Units. A BTU is, generally, the amount of heat required to raise the temperature of one pound of water one degree F. Specifically, a BTU is 1,055 joules, but the first definition is easier to understand in real-life terms. One "ton", in heating and cooling terms, is 12,000 BTUs.
