FAQs

Q?

What is the average life expectancy of a system?

A.

Most systems have a lifetime of 10 to 20 years. As your equipment gets older, its efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. When a unit begins to show its age, you have two choices -- You can overhaul the system or replace it. Because heating and cooling technologies improve over time, a new system designed with newer, more energy-efficient equipment makes sense, especially if your system is 7 or more years old

Q?

How can I reduce my energy costs?

A.

- Upgrade to a high-efficiency system - Swapping your old, inefficient air conditioning system for a high-efficiency one can cut electricity bills by up to one-third.

- Adjust the temperature - Typically, adjusting temperatures 5–8 degrees (down in winter, up in summer) can help save energy if you're going to be away from home for several hours.

- Have annual maintenance performed – Tuning up your cooling system each spring and your heating system each fall will  help ensure each operates at peak efficiency and can help you identify and resolve any potential issues before a breakdown occurs.

- Don't block vents in well-used rooms – Keep your supply and return air vents free of objects like blinds, carpets or furniture so your air conditioner can operate efficiently and there is even, cool air distribution.

- Close vents in less-used rooms – By closing the vents, you won't be spending money cooling rooms that are used less.

- Install a programmable thermostat – A programmable thermostat enables you to control your home's temperature when you're away or asleep. For every 1° you lower your thermostat for seven hours per day, you can save approximately one percent on your heating bill.

Q?

What determines if I need to replace rather than repair my unit?

A.

If your unit is 7 years old or older, requires frequent repairs or stops working, fails to heat or cool areas of your home, runs excessively or constantly turns on and off, or produces high utility bills, it can be more economical to replace your existing system.

Q?

Do I need to have my ductwork replaced?

A.

Industry experts estimate that as many as 70% of all homes with central air have poorly installed ductwork. Ducts that are not properly sealed or insulated fail to get the hot or cool air where you want it efficiently, therefore costing you money. Before you invest in a new system, make sure an HVAC expert checks your ducts and includes specific recommendations in their proposal to you. Don’t spend the money on a new, super-efficient system unless you are sure those efficiency gains won't be lost by poor ductwork.

Q?

How important is it to get the right size of heating and cooling equipment?

A.

Sizing HVAC equipment is very important from the standpoints of both comfort and energy use. Heating and cooling equipment that are over-capacity will not run as frequently or as long when it does run. In both cases, this may mean poor humidity control. It could also result in temperature variations or noticeable cycling. Over-capacity equipment will not be as energy efficient as properly matched capacity either. On the other hand, equipment that is under-sized, will obviously result in loss of comfort during temperature extremes.
