Ryan arrived 20 minutes early. A great start to our day as we had a plumber coming today as well. They did overlap, but Ryan was thorough, efficient and gave us a clean bill of health on our furnace in about 45 minutes. WE LOVE THOMAS HOFFMANN AIR CONDITIONING AND HEATING. Oh and get the combo service plan for both your furnace and AC annual service. Very reasonable.

Factors to Consider When Choosing an AC Unit

  • Size of Your Home
    • The square footage of your home is a primary factor in determining the appropriate AC unit size. A unit that’s too small will struggle to cool your space efficiently, while an oversized unit will cycle on and off frequently, wasting energy and failing to dehumidify properly.
  • Energy Efficiency
    • Look for units with high Seasonal Energy Efficiency Ratio (SEER) ratings. An energy-efficient unit can significantly reduce your cooling costs in St. Louis, where summers can be long and hot. The minimum SEER rating for new AC units is 13, but we often recommend systems with SEER ratings of 16 or higher for optimal efficiency.
  • Home Insulation and Sunlight Exposure
    • The quality of your home’s insulation and its exposure to sunlight can affect your cooling needs. Well-insulated homes with minimal sun exposure may require less powerful AC units, while homes with poor insulation or large, sun-facing windows might need more robust systems.
  • Humidity Control
    • St. Louis is known for its humid summers. Look for AC units with good humidity control features to ensure your home stays comfortable and free from excess moisture.
  • Ductwork Compatibility
    • Consider whether your current ductwork is compatible with the new unit if replacing an existing system. In some cases, ductwork may need to be modified or replaced for optimal performance.

Types of AC Systems to Consider

Central Air Conditioning

Central AC systems are popular in St. Louis homes. They cool the entire house through a network of ducts and are ideal for larger homes or those with existing ductwork.

Ductless Mini-Split Systems

Ductless mini-split systems are efficient for homes without existing ductwork or for cooling specific areas. They’re also great for additions or sunrooms.

Heat Pumps

Heat pumps can cool your home in summer and provide heat in winter, making them a versatile option for St. Louis’s variable climate.

Long-Term Considerations

When selecting your new AC unit, think beyond the initial purchase and installation costs. Consider factors like:

  • Warranty coverage
  • Expected lifespan of the unit
  • Availability of parts for future repairs
  • Potential for integration with smart home systems
  • Future energy costs based on the unit’s efficiency
