Whenever your outdoor unit (condensing unit) goes out, an air conditioning technician likely will recommend that you replace your indoor unit (air handler) as well. This is because your two units must be matched in order for your new outdoor unit to run at its promised level of efficiency. Furthermore, mismatched units may comprimise your level of comfort and may possibly shorten the lifespan of your new unit. However, there are times when a customer simply cannot afford to replace both units at once. When replacing an outdoor unit, Drake Heating & Air advises its customers on the costs/advantages of replacing a functioning indoor unit versus the savings/disadvantages of leaving the existing indoor unit in place. This allows our customers to make an informed decision regarding unit replacement, based on the condition of their current cooling system, their air conditioning needs, and their current financial situation. Unlike many contractors, we do not force our clients to replace both systems at once.
