Frequently Asked Questions

Q: Why should I replace my existing heating or air conditioning system?

A: You may wish to consider replacing your air conditioning or heating system if it is old, inefficient, or in need of repair. Today's systems are as much as 60% more efficient than those systems manufactured as little as 10 years ago. In addition, if not properly maintained, wear and tear on a system can reduce the actual or realized efficiency of the system.

If you are concerned about utility bills or are faced with an expensive repair, you may want to consider replacing your system rather than enduring another costly season or paying to replace an expensive component. The utility cost savings of a new unit may provide an attractive return on your investment. If you plan on financing the purchase, the monthly savings on your utility bill should be considered when determining the actual monthly cost of replacing a system. The offsetting savings may permit you to purchase a more efficient system.





Q: How expensive are air conditioning and heat pump systems?

A: Many factors affect the cost of a heating or air conditioning system, including the size of your home, the type and condition of the ductwork installed, and accessories you might need such as a thermostat or an electronic air cleaner. We have a complete range of systems and accessories available to meet all your needs, including your financial ones! We will be happy to assist you in finding the right system to meet not only your comfort needs but also your household budget.

Q: How do I select the right heating/cooling system?

A: First, make sure the unit is properly sized. We will provide a load calculation for your home if deemed necessary. We will also consider any comfort issues in the home. If you have allergies, an indoor unit with an ECM motor will allow you to circulate the air in your home continuously while filtering the air for about the same cost as operating a standard light bulb. Finally, know your budget parameters and the efficiency of the system being proposed. Does the system offer a payback? In other words, will the monthly savings over time offset the cost of the new unit or efficiency option being considered?

Q: What is involved in replacing an old system?

A: Aside from the placement of the new equipment, we will inspect several items and make a determination of whether or not these items need to be supplied or replaced. Some of the items include: ductwork, insulation, refrigerant piping, electrical service, wiring, thermostat, condensate piping, flue piping, flue terminations, chimney liner, slabs, filter, driers, registers, grills, drain pans, and evaporator coil.

Q: What is involved in installing a new system?

A: If a system is being added to the home for the first time, most of the items noted in the previous question and answer may be required to install the new system. Besides the equipment, the most significant component is ductwork. The ductwork can be either metal or fiberglass ductwork. The ductwork needs to be properly sized to deliver the right amount of air to each room. The ductwork consists of supply and return ductwork. The supply duct is attached to the outlet of the furnace or air handler and delivers air to individual zones in your home. We will determine the size of the ductwork going into a space by the amount of air that needs to be delivered to the space, per the specifications listed by the manufacturers.

Q: How long can I expect a new system to last?

A: If you have a qualified technician perform regular preventative maintenance and service suggested for your unit, industry averages suggest that an air conditioner should last 12-15 years (sea coast applications may be less) and a gas furnace should last as many as 20-25 years. (Please see our "maintenance contract" area for more details on our services.)

Q: What are some preventative maintenance things I should be aware of?

A: With the proper attention, heating and cooling systems can keep you comfortable year-round. Heat pumps and air conditioners need a yearly professional tune-up. A check of the heat pump should include an inspection of the compressor, fan, indoor and outdoor coils and refrigerant lines. Indoor and outdoor coils should be cleaned, and the refrigerant pressure should be checked. Drain lines should be cleaned and tested.
