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 ]

Not necessarily, however there are many considerations here. Similar to the question above, if you think you are going to need to replace your furnace in the next 24 to 36 months, you should consider having it installed with the air conditioner, i.e., a complete system. With the new higher efficiency system you'll probably qualify for cash rebates, low interest financing, and far better warranties than when you replace one component at a time.

Most furnaces and air conditioners last between 15 and 20 years, but by replacing your furnace and/or air conditioner before its life expectancy is up with a high efficiency furnace and/or air conditioner can save you money on your gas and electric bills.

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.

Absolutely. By having our highly trained technicians installing a new high efficiency furnace and/or air conditioner, your gas and electric bill will usually be cut in half. Insulation quality in your home is also important in keeping your heating and air conditioning bills lower.

YES! A new 15 SEER air conditioner can usually cut the electricity used by the old air conditioner in half. Even a 12 SEER air conditioner (this is the minimum efficiency the federal government allows to be sold) will cut the electricity used by approximately 40%. A new 90% furnace can usually cut the gas used by the old furnace by as much as 30%, and a new 80% efficient furnace (minimum allowed by the federal government) will use approximately 20% less. [ back to top ] Yes, this is fine.

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. McCullough Heating & Air Conditioning can design a central air conditioning system for you and provide you with a fixed price quote to install it.

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.

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.
