1) Annual inspections are a must! This includes a seasonal performance check & an inspection for cleanliness. Mold can grow really fast if left unchecked for a season or two. Gone are the days of "if it ain't broke, don't fix it"~ You need to have a service tech looking at your equipment for anything that could cause a break down. Lets try this Trite phrase " An Ounce of Prevention, or a Pound of Cure"; how about "you can pay me now, or you can pay me later."
2) The duct work is as important as the A/C equipment. When you operate the newer high efficency equipment of the modern day, you need to have a duct system that is sealed to less that 5 % leakage of the overall airflow. A recent Department of Energy study shows many typical duct systems leak 25-40% of their airflow & cooling capacity. If your system is sealed to 5% or better you will be very happy, comfortable and financially secure with your A/C purchase. Not only does this save money on the Utility bill, it makes the home more comfortable by reducing humidity and causing less wear & tear on the equipment due to reduced run requirements.
3) Duct Leak Testing is common & affordable. Negative pressure testing on the duct system will tell you where you are losing comfort & energy. Check into it near your home location. It ranges from $100 to $500 depending on the scope of the testing~ get 'em to check the house leakage while they're at it! Alot of companies will include the testing if you are considering changing out the equipment. Don't use a contractor that can't perform duct leakage testing. If they don't offer the test, Find a company that does ~ it shows that they are "up to snuff" on current trends in Home Comfort & Energy Efficency. The A/C equipment you are buying will last at least 15 years and if your ducts leak, you will continue to have high utility bills, equipment problems, & IAQ issues for the next decade and a half. Not to mention the cost of future energy!! It's 2010 people, Consumers Should Demand Excellence from A/C Contractors!
4)When it's time for Air ~ "Be Prepared" ~ Schedule early & commit to a service agreement and as part of your commitment ask these things of your service provider: "Do I have priority service if I have a break down?" "Do I get a discount on required parts or Labor?" "What can I do myself to ensure I won't need you between service intervals?" ( Examples: filter, drainline, Thermostat operation, Ect. Ect.)
