  • Efficiency of Your System. If your system is older, it may cost you a lot of money to operate it on a daily basis. Is your energy bill more expensive every month? Purchasing an energy efficient system can save you money in the long run.
  • Expensive Repairs and Frequent Breakdowns. It is important to weigh the cost of repairs and purchasing a new unit. How frequently are you having to repair your system? Are they expensive repairs? Is it worth it to pay for repairs?
