Introduction

Welcome! This guide is for homeowners that are looking to replace their existing central air conditioner with a new unit. We go through some of the important points when looking at options. SEER = Seasonal Energy Efficiency Ratio, higher the SEER the less electricity required to cool.

What Efficiency?

Today's regulation requires that manufacturers produce at a minimum of 13 SEER rating for their central air conditioners. Here in Wisconsin we are a strong believer that we need to invest in a good furnace before worrying about our air conditioner. This is the complete opposite of those in Florida. Most of our customers find the sweet spot for central air conditioners between the 13 and 16 SEER rating.

What Blower?

Even though the blower motor is part of the furnace, it does come into play to determine the air conditioner's efficiency rating. Ask your estimator about what type of blower you have in your furnace. If you have a PSC blower motor (standard efficiency), adding an evergreen motor to your furnace you can get an extra boost to your energy savings. Blower upgrades pay for themselves in 3-7 years* depending on use.

Proper Air Flow

If you had problems getting good air flow with your existing air conditioner now is the time to bring this up with your estimator. Talk to them about what rooms are not getting good air flow. They can take a look at duct work and make sure that everything is properly sized and if there is anything they can do to assist.

R410 or Bust

Your existing air conditioner is most likely an R22 refrigerant. R22 is being phased out and the price of the refrigerant is astronomical compared to where it has been the past decade. There is a chance that you're situation is your current system has a leak and we have to keep adding R22. Current systems use R410A and it is much more reasonable and is also better for the environment over R22.

Quality & Trust

Find a company you trust to do the work. Air Conditioners have so many points where there could be problems. Find a company that has been around and will be around in the future if you need them. Make sure they register all equipment with the manufacturer and that any additional warranties are done through the manufacturer. Check with friends and family to find someone that they have had good experience with.

Conclusion

Find a good balance of price and comfort. Make sure you get one with R410A refrigerant and that a company you trust installs it. You can upgrade your blower motor if you have a standard PSC motor on your furnace.
