Tom was able to offer the solution to my hot water heating system that other major companies had not been able to figure out for years. It was a significant undertaking, but also very reasonable in price. Installers Nick and Chris are also very nice people to work with. The heat in our house now works better than it ever has.
Response from the owner:Thank you, James! We're glad Tom could provide the solution you needed and that Nick and Chris made your experience positive. It's great to hear your heating system is working better than ever!

Ryan has been a pleasure to work with. Unfortunately, to complete the installation of the contracted systems, there's still work to do getting the right vents in place, completing the thermostat placements, adjusting the airflow in the upstairs bedroom, etc. He's scheduled to come back next week and hopefully we can get this all finished.
Response from the owner:Thank you, Michael, for your feedback! We're glad to hear you've enjoyed working with Ryan. We'll make sure everything gets completed during his next visit.

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
