Common questions

Why should I replace my existing system?

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 ten 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.

How do I select the right system?

First, make sure the unit is properly sized. Randall's Temperature Control will provide a load calculation for your home. We can provide an energy analysis to determine operating cost. Next, consider any comfort issues in the home. Some products can reduce air stratification and uneven temperatures from room to room. 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?

How long can I expect my new system to last?

If you have a Randall's Temperature Control qualified technician perform regular preventative maintenance and service suggested for your unit, industry averages suggest that an air conditioner should last 12-15 years. A gas furnace should last as many as 20-25 years.

Where do I get replacement parts?

Specialized replacement parts for your HVAC system can be hard to find. You can contact the manufacturer of your present HVAC system or call Randall's Temperature Control to see if we can possibly help you locate your parts. This might be a safer decision because some replacement parts have specialized technical instructions that have to be followed to assure the part is installed correctly and safely. When in doubt, call us at Randall's Temperature Control and we will be glad to assist you.

How expensive is a new system?

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! Randall's Temperature Control will be happy to assist you in finding the right system to meet not only your comfort needs but also your household budget. Call us today and see what we can do for you today.

What is involved in replacing an old system?

Aside from the placement of the new equipment, your Randall's Temperature Control 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.

Should I replace my indoor coil?

When replacing your air conditioner or heat pump, the answer is most likely yes. The efficiency ratings that are advertised for an air conditioner or heat pump are based on the performance as part of a matched system. If only the outdoor portion is changed, the efficiency and savings could be less than that of a matched system.

What is covered in my warranty?

All products that we sell and service, come with a written limited warranty on parts. This warranty states that a replacement part will be furnished for any part of the product that fails in normal use and service during the applicable warranty period specified in accordance with the warranty's terms. Randall's Temperature Control can review with you the warranty periods for the products you select.
