Heating and Cooling

WarrantyCompare each manufacturer’s warranty on key components and parts. Initial savings on lower-cost products can evaporate if key components fail after they’re out of warranty. Strong warranty programs ensure you’re protected.

Energy EfficiencyBy selecting products with the recommended efficiency ratings for your area, you can save on your utility bill. Compare the purchase price and operating costs of similarly rated products for an apples-to-apples comparison. Also, the Department of Energy (DOE) has established minimum efficiencies that require heating and cooling products to be significantly more energy-efficient than products manufactured prior to 1992.

Comfortable OperationMake sure your new system will meet your comfort requirements! Things like quiet operation, even-air-flow and moisture control all affect your system’s overall performance and your comfort level. And not all systems are created equal! Check to be sure that your system operates to your required specifications.

System Analysis & Design By A ProfessionalIf your present system is more than 10 years old, your dealer may perform an analysis that evaluates duct sizing, runs, and registers in your home. In addition, if you’ve made changes to your home since your last system was installed, these may affect your heating and cooling needs. Make sure your dealer knows about these changes.

Because heating and cooling requirements vary by building, geographical area, and the specific needs of the occupants, products are available in a wide range of capacities, performance options, and features. That’s why a trained, professional contractor should help you choose the right system for your home or business.

Preventive Maintenance PlansAsk what maintenance or service plans a dealer offers. Regular maintenance on heating and cooling equipment will ensure that it continues to perform efficiently for years.
