Frequently Asked Questions
Question: How important is an air filter in my heating and cooling system?
Answer: It's a fact: the trapped air we breathe in our homes can be loaded with dust, pollen, plant spores, and other pollutant particles. In many cases, it's worse than the air outside.
Question: After my air conditioner runs for a while, ice forms on the big pipe outside and it stops cooling. What could be the problem?
Answer: More than likely, it's either low on refrigerant or low on airflow. As a homeowner, replace your filter and allow the unit to thaw out. If the problem reoccurs, call Advanced Roofing's Air Conditioning department to schedule service on your system. We recommend having annual maintenance performed to keep your systems in peak operating conditions. Ask your ARI Air Conditioning representative about our energy saving maintenance agreement program.
Question: What does SEER mean?
Answer: SEER stands for "Seasonal Energy Efficiency Ratio". Basically it tells you how efficiently it converts electricity to cooling comfort. The higher the SEER rating, the more efficient the system will operate. By federal law all units must be a 13 SEER or higher. ARI Air Conditioning recommends having a Comfort Consultant to come to your home and perform a heat load calculation to insure the proper size unit is installed. This is a free service to our customers that may help you save money and increase your indoor comfort.
Question: Why is the upstairs of my house always hotter? What should I do?
Answer: Heat rises, thus the reason it's hotter in the summer. Assuming the system was sized and installed correctly, you should consider installing a zone system if possible. Sometimes the addition of return air ductwork will help improve air movement and help make upper levels more comfortable.
Question: Should I get my ducts cleaned?
Answer: Cleaning your ducts may be beneficial in improving your indoor air quality. A premium whole house duct cleaning will help decrease the spread of contaminates in your ductwork and home. New construction homes can benefit from having the ductwork cleaned to remove drywall dust, sawdust and other debris from the construction process.
Question: What's that black stuff on my ceilings and vents?
Answer: Burning candles can be the culprit for the black on your walls and ceilings as well as polluting the air your family breathes. Keep wicks trimmed to no longer than 1/4th of an inch to help reduce soot from the candles.
Question: I have friends and relatives that have installed UV lights. What are they for and why do I need one?
Answer: UV is the abbreviation for ultraviolet. Located in the return air ductwork and by the indoor cooling coil, the ultraviolet air treatment system continuously emits high - intensity ultraviolet (UV) energy. The energy eliminates (kills) a very high percentage of airborne bacteria and germs passing over the UV light field inside the ductwork. The UV light mounted next to the indoor cooling coil will help eliminate the growth of mold, mildew and other contaminates from the drain pan and coil surface. At ARI Air Conditioning we recommend installing UV products.
Question: My air conditioner is new, do I really need to have it cleaned?
Answer: Yes!! Even though your system is new, it still needs to have annual maintenance performed. This will help keep the warranty in effect. Most all equipment manufactures state in the terms of their warranty that annual maintenance must be performed by a qualified technician. Keeping your system maintained will give you assurance that it is operating at peak efficiency and safety.
Question: Whats' the difference of R-22 & R-410A refrigerants operating AC Systems?
Answer: The term "refrigerant" means any Class II substance used for heat transfer in a refrigerating system, according to the U.S. Environmental Protection Agency. Refrigerant is the gas used to heat or cool the air in heat pumps and air conditioners. Without refrigerant, these appliances would operate only as fans. Most residential air conditioners and heat pumps rely on hydrochloroflurocarbons, or HCFCs, for this purpose. The one most often used is called HCFC-22, or R-22, known as Freon®. About 10 years ago, the federal Clean Air Act was amended to begin a mandatory phase out of the production and use of many ozone-depleting substances, including R-22 and R-12, which is found in vehicle air conditioning. Products using R-22 will be phased out by Jan. 1, 2010, and a total ban on production and importation becomes effective in 2020.
Puron® is a brand name for a refrigerant called R-410A. Several air conditioning and heat pump manufacturers are using 410A because it operates at higher pressures and higher efficiency is easily attainable. The other huge factor is that 410A is a environmental friendly Freon that does not contain any ozone depleting molecules.
