While there are many variables in any particular home or building, the main decision points regarding repair or replacement of your air conditioning and heating system are not difficult concepts.
One of the most direct points to consider regarding replacement of your HVAC system is simply its age.
Consider installing ENERGY STAR qualified heating and cooling equipment.
If your HVAC equipment is more than 10 years old or not keeping your house comfortable, have it evaluated by a professional HVAC contractor. If it is not performing efficiently or needs upgrading, consider replacing it with a unit that has earned the ENERGY STAR. Depending on where you live, replacing your old heating and cooling equipment with ENERGY STAR qualified equipment can cut your annual energy bill.
Replacing your old heating and cooling equipment with new, energy-efficient models is a great start. But to make sure that you get the best performance, the new equipment must be properly installed. In fact, improper installation can reduce system efficiency by up to 30 percent — costing you more on your utility bills and possibly shortening the equipment’s life.
New Equipment is Easier on our Environment.
If the payback period from a financial point of view will take longer than you expected, consider this: diverting your monthly spending from higher energy and repair costs to new equipment helps save fossil fuels and slow CO2 emissions. Though difficult to place a specific dollar amount upon, it makes sense to consider this benefit.
