Not always. In fact, there are three factors you should carefully consider when trying to determine the best system and the best value for your home:

1. Determine your current utility costs so you can calculate the potential savings of a new system.

2. Consider how much longer you expect to own or reside at the service location. Will you be there long enough to reap the benefits – and the long-term value – of your investment?

3. Think about your own personal lifestyle and daily schedule. For example, the heating or cooling preferences of a senior couple who spends most of their days at home will differ greatly from those of a young professional who lives alone and travels four business days each week.

Our service technicians are trained, experienced, and have the hands-on skills to work on virtually any brand of heating or cooling equipment, new or old. For new installations, we offer a broad range of furnaces and air conditioning systems from a number of leading manufacturers, all of which offer essentially the same high efficiencies and warranties.

Following our comprehensive evaluation of your home or business, we can provide you with multiple options, ranging from builder’s models to top-of-the-line equipment. And since our installation rates are exactly the same, regardless of which brand you choose, you can make your choice with confidence, knowing that our recommendations are based on your needs and your lifestyle, not your bank account.
