How to Shop for the Right Air Conditioning Installation in St. Louis, MO

There are a lot of factors that go into making any purchase, especially when you’re buying something that’s supposed to last for a long time, like an air conditioning unit. In this blog we’ll delve into the top five things to consider before buying a new unit.

Unit size and capacity

Consider how big of a unit you actually need. A 3,000 square foot home won’t be sufficiently cooled by a unit that’s too small. Conversely, a two bedroom condo probably doesn’t need the biggest unit on the market. A unit that’s too big will cycle on and off more frequently, which wastes energy and will drive up your electric bill!

The first step in the air conditioning installation in St. Louis, MO process should be hiring an HVAC contractor to measure your square footage and determine what size unit you need.


Air conditioners have come a long way from the old window units. Today’s units can come with a variety of features that you may or may not want or need. Of course, each feature you add is going to increase the price.

Some units are designed to limit noise, as low as only 21 dB loud. To put that in perspective, a standard library is about 30 dB. High end air filters on your unit are designed to sterilize the air coming into your home and potentially eliminate some common allergens such as pollen. Some of the most advanced units can even be Wi-Fi enabled to be controlled from your smart phone.

An important factor that you might consider paying more for is a unit that has a higher energy efficiency rating.

Energy efficiency

Every air conditioning model must be evaluated for energy efficiency. Each model is given a Seasonal Energy Efficiency Ratio (SEER) number. The lowest acceptable number is a 13. Some of the most advanced models have a SEER of up to 26. The higher the SEER number, the more expensive your unit is likely to be, but you’ll end up saving money down the line. It’s estimated that with every two-point increase in SEER rating, you can save up to $25 each month on your electric bill!


Cost is a huge factor in determining anything you’re buying. As we’ve said, more features mean a more expensive unit, but sometimes paying more for a very energy efficient unit will save you money down the line.

The two costs associated with air conditioning installation in St. Louis, MO are the price of the unit and the cost to have it installed. You can definitely save money by purchasing a cheaper unit, but again, you get what you pay for. A brand name unit is more likely to last you longer.


The old adage “you get what you pay for” remains true in the air conditioning unit world. There are many different brands out there, at Ashley Brothers, we only rely the top brands like Amana, Goodman, Ruud and Weil Mclain. You can be sure these brands will be energy efficient, come with all of the features you need, and last for a long time.

Consider all of these factors before you go out and buy a new unit to brace yourself for the heat in St. Louis this summer.
