Modern air conditioning systems often use fan delay timers to keep the circulating fan running after the thermostat is satisfied. The reasoning is pretty simple: The evaporator coil is still cold, so it makes sense to get all the cooling you can for the money you're spending in energy. Furnaces have always run for a short time after the call for heating has ended.

McCullough’s comfort consultant will measure your home and calculate the actual heating & cooling load on the home (calculation using Manual J v8 that incorporates information about window size & direction, walls, ceiling, floor, appliances, insulation, etc). This will determine the proper size of equipment and ductwork that is needed.

Generally allow one day for replacing a heating and air conditioning system. Installing a brand new central heating and cooling system, including ductwork , may take two days. Be aware that reputable contractors will refuse to install a new air conditioning system or heat pump system when it is raining. This is due to the fact that when moisture gets inside refrigerant lines it can be very damaging and can cause reliability and maintenance issues. [ back to top ] See similar questions...

Generally 12 - 15 years. Of course, this depends on several factors, among them how the system has been maintained, quality of construction, and environmental quality. Regular preventative maintenance has been proven to extend the useable life of your system, but many people only have their system maintained when it breaks down. Quality of construction is another factor. Some lower tier units just aren't built as well as other brands, and they don't tend to hold up well as they age. See similar questions...

Yes. Air conditioners require more air flow than furnaces and it may be necessary to add more ductwork. Also, local codes require that your ductwork be insulated in attics and crawl spaces, and your electrical service may need to be upgraded.

The ideal location for the air conditioner is typically a compromise. We try to find the out-or-the-way location that is close tot he furnace room and the electrical panel. the farther away the outdoor unit is from the furnace, the more it costs the homeowner in installation costs. Proximity to neighbours is also a factor - you don't want your unit impinging on your neighbour's property! The best location is also one that gets a lot of shade. See similar questions...

Generally speaking, yes you should. If, however, you've recently replace one component, you may not need to replace everything. For example, if your furnace was installed within the last 5 - 7 years you probably will be okay just installing a new condenser and coil. Beware of companies who insist on replacing everything, or who claim that you'll void warranties on your condenser if you don't replace your furnace - that's a load of horse hooey.

Central air conditioning helps keep your home cool and reduces humidity levels. By transferring heat from air located inside your home to the outside, conditioned and cooled air is left to be re-circulated. Using electricity as its power source, the compressor inside an air conditioning unit pumps coolant, or refrigerant, back and forth to gather heat and moisture from indoors. See similar questions...
