St. Louis Air Conditioning Consumer Information

Hoffmann Brothers, a St. Louis air conditioning contractor, answers frequently asked questions on buying an air conditioner (AC).

What is the relevance for buying an EnergyStar certified air conditioning (AC) unit?

Heating and cooling systems labeled with the EnergyStar label have to pass stringent guidelines. The U.S. Environmental Protection Agency establishes specific energy efficiency standards, which promote indoor comfort and energy savings to reduce greenhouse gas emissions?

What basic features distinguish an EnergyStar qualified air conditioner from a standard one?

The EnergyStar qualified air conditioner optimizes energy efficiency by at least 10%. Timed controlled settings and seasonal energy efficient ratios (SEER) fuel many EnergyStar units’ energy conservation. It costs the typical single-family residence $1900 to $2,200 a year to heat and cool the home.

What mistake do St. Louis consumers prevalently make when purchasing a new AC?

For some reason, consumers misconstrue a larger air conditioner as the best solution for keeping a house cool. In contrast, an oversized AC wastes energy. Because air conditioners work to remove humidity and hot air, an ill-sized unit will rapidly cool a room but not have the capacity to remove the moisture. In St. Louis, lingering humidity gives way to a damp indoor environment.

What is a “quality installation” for an air conditioning unit?

The EPA reports that more than 50% of U.S. homes have an improperly installed AC. An incorrectly installed air conditioner attributes to higher annual monthly bills. With a quality installation, a cooling contractor sizes the correct sized AC; confirms the right refrigerant charge; and verifies that air moves via the cooling coils at the appropriate rate.

How to calculate the appropriate sized cooling system for a home?

British thermal unit (BTU) represents the measurement of air conditioners cooling capacity. Sizing an air conditioner entails taking a space’s size and pairing it to the corresponding BTU capacity.

For example, 100 to 150 square foot room needs 5000 BTSs per hour to keep the space cool. If the room happens to a kitchen where the oven and dishwasher are in regular use, plan for an additional 4000 BTUs.
