Next, consider the maintenance history.
The moment you drive that new car off of the dealer’s lot, its value drops by about 10%. That is one reason why used car sales are a huge business. The manufacturer’s warranty usually lasts for “three years or 36,000 miles” so the dependability of a nearly new car is usually not a concern. And there still may be a trace of the original “new car smell” that appeals to those not averse to inhaling a petrochemical vapor. Older cars with more mileage may come with a 30-day dealer’s warranty and the lower price will appeal to those on a budget. Purchasing an “old clunker” with no guarantees is a gamble. Homeowners that need to replace their HVAC system may wonder: Should I replace my old HVAC system with a used unit to save money? First, consider that while a used car can be taken for a test ride, there is no way to take a used HVAC unit for a spin unless it is already installed in some other house. Next, consider the maintenance history. Has it been kept clean and well maintained by a qualified HVAC professional? The answer is likely no as idle HVAC systems are often neglected which is why they are idle in the first place. And even if you find a used HVAC system in good condition and a great price, is it the right size for the house it will serve? Most reputable HVAC companies will not even consider installing a used HVAC unit because used systems will lead to problems just like those owners of “old clunkers” experience. With a new HVAC system, there are financing options and energy savings to be gained that make a new system quite affordable for any budget.
