FAQ's
How often should I change or clean my filters? Generally, disposable filters should be replaced every month that the system is running. Replacement filters should be the same kind and size as the original filter. If your filter is not disposable, follow the manufacturer's instructions for cleaning procedures. Back to top of this page What do all those rating numbers mean to me? The federal government requires all air conditioning and heating equipment to be rated as to efficiency. The higher the rating, the more efficient the model. For cooling, the rating is SEER (Seasonal Energy Efficiency Rating); heat pump heating is HSPF (Heating Seasonal Performance Factor) and gas furnaces are rated with AFUE (Annual Fuel Utilization Efficiency). The experts at Arthur Air Conditioning will be glad to assist you with efficiency rating comparisons. You may also contact your utility provider or reference the ARI Directory for information. See: SEER Rating: Is Bigger Always Better? Ask us about our Energy StarSM Products. Back to top of this page How much will my new air conditioning system cost? The answer is: "That depends." There are many factors which must be considered: the efficiency of the equipment, the size of your home, the condition of the duct work, and whether you need a thermostat or electronic air cleaner. In most cases, replacing your whole system (indoor and outdoor components) will result in a more efficient, longer lasting system but will also cost a little more.

Air conditioners are manufactured to withstand all possible climate changes. In fact, rain helps keep your unit clean. Of course, because heat pumps run all year long, they should never be covered. Back to top of this page 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 uses much less electricity than conventional motors. Back to top of this page Is there any advantage to setting my thermostat fan to "ON" so the fan runs constantly? There are a couple. One is that you get constant filtering of the air in your home. The other is that because the air is moving, you have a more even temperature throughout. Back to top of this page 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 to take in and exhaust air to operate efficiently. If air cannot circulate, the unit could build up heat and require service. Back to top of this page 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? Air conditioners are designed as matched systems, with an efficiency rating given for the whole system. If you replace only one part, you do not get the advantage of many technology changes that make the system work efficiently to ensure comfort. Also, the indoor system contains a cooling coil which may be partially blocked by particles that will decrease efficiency. Further, if your whole system is replaced, you will be less likely to need service in the near future. Back to top of this page What is a ton of air conditioning and what size system do I need for my home? There are many things which will determine the size (capacity) system your home requires. Some of these are: square feet to be cooled, climate, humidity, number of windows, insulation factors, which direction your home faces, heat-producing appliances, and even the number of people who will be in the home. Arthur Air can do an energy analysis on your home and help you decide what your particular needs are for your lifestyle. Back to top of this page How do I find a dealer who will do a good job? The same rules apply here as for any contractor. Ask people you know who have had an air conditioning system installed and if they would recommend that contractor. Check with the Better Business Bureau. Have the dealer come out and give you an estimate--see how they handle their customers. Ask for references--and then check them. See: Customer Service: A Moving Target Back to top of this page What is the difference between a Manufacturer's Limited Warranty and an Extended parts and labor Warranty? A limited warranty covers specific parts (i.e. Compressor, coil, electronics, etc.); therefore, it is limited by the language in the warranty. Extended warranties are generally purchased in addition to the equipment. Extended warranties cover all parts and may also include the labor for the service call. An extended warranty protects you from unexpected and unbudgeted service calls for the duration of the warranty. Back to top of this page |
