How to Compare Central Air Conditioner Brands

Although it's not decorative, an efficient air conditioner improves your home environment in the summer months.

If your central air conditioner is wheezing or you have just learned its core is kaput, it's time to consider replacing the entire unit. Using an internet search engine, a telephone and some common sense, you can locate both a quality central air conditioner and a responsible contractor and restore your happy summer home environment.

Instructions

1. 

   A little math will help you find the right air conditioner for your home.

   Calculate the cooling capacity your space requires here:

2. 

   Investigate each candidate for a replacement air conditioner.

   Compile a small list of qualified HVAC (Heating, Ventilating and Air Conditioning) contractors in your area. Visit each company's website or phone their offices to find out which brands of central air conditioners they install.

3. Research each brand, making a list by model of capacity, SEER (Seasonal Energy-Efficiency Rating), equipment warranty and price. Add energy-efficiency incentive data to your list for each model you research. Local utility companies, your state, the federal government and the manufacturer may offer tax credits or rebates when you install a qualifying air conditioning unit. Doing so saves your household money throughout the life of the machine.

4. 

   HVAC contracting firms will send a representative to your home.

   Arrange in-home consultations with at least two contractors and evaluate their pricing, service warranty, maintenance plans and that intangible facet, whether you think you trust them. Then select a company and a new central air conditioner.

Tips & Warnings

• Expect to replace your central air conditioner approximately every 20 years.

• A bigger central air conditioner than your space requires will waste money two ways: it will cost more to install and will use more power over its lifetime.

• An air conditioner will operate at its rated efficiency (SEER) only when teamed with the appropriate coil. Invest in a new coil when you install a new air conditioner.
