Frequency Asked Questions
Why is a matched system so important?
A matched system is important for a variety of reasons. One is comfort. When all your components are properly sized to your home, you can control exactly how much heating or cooling you need so you can relax. Also, a properly sized matched system enables every component to perform as designed, meaning proper cycle times are maintained, humidity is controlled, and system sound is minimized. Another reason matched systems are important is efficiency. Most systems people buy are too large for their homes, meaning they pay to heat and cool space that isn’t even there. A matched system outlined by a dealer who has completed a load calculation for your home provides just the right amount of heating and cooling you need so you get the most value for your utility dollar.
I keep my home very clean. Could the air in my home still not be clean?
Yes. Consider that the average home generates 40 pounds of dust for every 1500 square feet of space. While regular home cleaning is an excellent measure to reduce exposure to irritants and pollutants, it’s simply impossible to remove enough of the material by hand to make your home’s air as comfortable as it can be.
What are the advantages of units with variable speed fans?
Variable speed fans operate on a simple principle: they are able to spin at different speeds depending on the heating and cooling needs of your home. Usually, they operate at lower speeds, delivering a steady, reliable stream of warm or cool air to your home. This helps control humidity levels, utility costs and system noise. When conditions become more extreme, the fan speed increases so that the system can meet increased demand, guaranteeing that on even the hottest days or coldest nights, you’re comfort needs will be met.
I need a new outdoor unit, but my indoor unit works fine. What are the advantages of replacing my whole system at the same time?
We recommend that your replace the indoor coil or air handler when replacing the outdoor unit. Both of these components are integral to the closed refrigerant loop and together determine the capacity and efficiency of your system. If you do not replace the indoor unit, there will be no test data available for the new combination to establish the expected capacity or efficiency of your system. Also, the indoor system may be partially blocked by particles that will decrease efficiency, and you may be faced in the near future with replacing the indoor unit after it fails and having to pay to have the closed refrigerant system opened again. It would be expensive and be another opportunity for contamination. You end up paying more. If your whole system is replaced, you will be less likely to need service in the near future.
Will anything help control the humidity in my house?
Humidity is a problem in many areas. The best way to control excessive humidity is to have a system that runs longer at lower speeds. Variable-speed air-handling equipment runs at very low speeds, which keeps the air circulating against the cooling coil and removes much more moisture than conventional systems. At these low speeds, the variable-speed motor also uses much less electricity than conventional motors.
What is a load calculation and why is it so important?
A load calculation determines what the proper size system is for your specific home. Completed by your dealer, it factors in a number of criteria used to determine what size components you should include as part of your total comfort system, things like square footage, number of windows, and year-round weather concerns. A load calculation is important so that your system operates at maximum efficiency, with optimum performance. Most homes have systems that are oversized, so you end up paying more than you should to heat and cool your home. Also, systems that are improperly sized tend to cycle too quickly or too slowly, and that can lead to maintenance problems, uneven temperatures, and an inability to control humidity. A properly sized system based on a correct load calculation can help ensure you enjoy long-lasting, reliable comfort whatever the season.
What size system do I need for my home?
It is important that new or replacement equipment is not sized by “Rule of Thumb” or by duplicating the existing equipment capacity. The only accurate way to determine the correct capacity of heating and air conditioning equipment for your home is to have a load calculation performed on your home. There is a specific method available to all dealers to do this calculation. This will give your dealer the heat gain and heat loss design data for your home. These figures can then be used to select the appropriately sized air conditioning or heating system for your home, based on equipment-performance data. Many factors determine the size (capacity) system your home requires. Some of these are: square feet to be cooled and heated climate humidity number of windows insulation factors which direction your home faces heat producing appliances, and the number of people who will be in the home Oversized air conditioning systems will not remove adequate moisture from the indoor air due to short cycling. Also, oversized systems quickly cool the indoor air temperature, but they do not run long enough to remove the humidity. That leaves you feeling stuffy and uncomfortable. Control of your home’s climate is rarely achieved with oversized systems and electricity consumption is higher than with a properly sized system. An oversized furnace is similar to an oversized air conditioning system. The furnace run time is short, creating uncomfortable air stratification and less air filtration. Also, the frequent cycling of the unit on and off can cause undue wear and tear on internal working components. An undersized air conditioning system will not adequately cool your home on the hottest days and an undersized furnace will not adequately heat your house on the coldest days.
How much will my new system cost?
That depends. There are many factors that must be considered. These include: The efficiency of the equipment The size of your home Is the ductwork installed and in good condition? Do you need a thermostat or electronic air cleaner? In most cases, replacing your whole system, including both indoor and outdoor components, will result in a more efficient, longer-lasting system but will also cost a little more.
How close to the outdoor unit should I plant shrubs or flowers?
Manufacturers generally agree that plants should not be closer than 18 inches. Air conditioners need intake and exhaust air to operate efficiently. If air cannot circulate, the unit could build up heat and require service.
