If the temperature in your home has cooled enough to satisfy the thermostat and the compressor on your air conditioner or heat pump continues to run, you may have a failed contactor. The steel contacts are likely to have become welded together, causing the failure. Although a contactor's ultimate demise can be delayed by using some methods we do not advise, without addressing the issue, significant damage may be caused to the compressor. Most if not all mechanical failures of contactors can be prevented by owning an annual preventative maintenance agreement on your HVAC system. Corrosion and wear can be easily identified and replaced at a fraction of the cost compared to a demand service call in the middle of summer. However, if your Orlando air conditioning system has failed due to a faulty contactor, Melco HVAC Services of Orlando can have that part replaced and your system cooling and heating again in just a short time. Our technicians are close to your neighborhood with fully stocked service vehicles.
