First of all, make sure you will be working with somebody who is experienced in installing air conditioning units - a reliable contractor. The existing ducts and the model/manufacturer you have gone with may greatly influence the service fee of the contractor. Research will be your best friend as you want to check as many quotes as possible and as many potential contractors to work with you, or units to purchase. There is no substitute for quality installation experience. Be thorough when gathering data and checking references.
Air conditioner units use electricity to run. Your electric bill could multiply exponentially - really, it could - if you use this appliance on a regular basis. This is especially true in warmer climates where it is a necessity to cool the home. It is advisable that if you live in a warm weather locale, you should research into the unit's efficiency to keep those disconnection notices at bay. This may mean a larger initial investment, but should save money in the long run.
The efficiency rating is required to be on all air conditioners. So that you can narrow down your choices, you would want to compare each model carefully with each other. And with greater efficiency, the greater your savings will be on your electric bill. The costs of running an efficient air conditioner are less as it exerts less energy when cooling a house or building.
You will need to determine the appropriate size of the unit needed for your house. This is an important step because units that are too small will have to work harder to cool the home. Units that are too large are simply wasteful and unnecessary. A qualified air conditioner contractor will be able to analyze the size of your home and make recommendations on the size needed.
Before enlisting the help of a contractor, you definitely would need a contract. Ensure that all costs are clearly detailed and not shrouded in double-talk. These costs should include the costs for both unit and installation. Any payment terms and warranty details must certainly be included. Generally, a warranty should include the cost of the compressor, among other parts. Avoid touching a unit that does not have a five year warranty or greater - ten years warranty is the most ideal time frame. As for additional parts, they may come with a separate warranty and be valid between one to five years.
