Installing a new air conditioning system is a significant investment, and a proper installation ensures maximum efficiency and longevity. Unfortunately, many homeowners and even some inexperienced contractors make avoidable AC installation mistakes, leading to performance issues and costly repairs. If you are in the St. Louis area and considering a new AC unit, understanding these common mistakes can help you make the right choice for your home.

1. Choosing the Wrong AC Unit Size
One of the most critical mistakes in AC installation is selecting a unit that is either too large or too small for your home. An oversized unit will short cycle, leading to higher energy bills and inconsistent cooling, while an undersized unit will struggle to cool your space efficiently. A professional HVAC technician from Galmiche & Sons can perform a load calculation to ensure the right-sized AC unit for your home.
2. Incorrect Placement of the Outdoor Unit
The placement of the condenser unit plays a crucial role in system efficiency. Installing it in direct sunlight, near obstructions, or too close to walls can restrict airflow and increase operational strain. Ideally, the unit should be placed in a shaded, well-ventilated area to maximize efficiency.
3. Poor Ductwork Installation
Leaky, poorly sealed, or improperly sized ductwork can lead to energy loss, uneven cooling, and increased strain on the system. Professional ductwork design and installation ensures that ducts are sealed, insulated, and appropriately sized for optimal airflow throughout your home.
4. Improper Refrigerant Charge
A common AC installation mistake is improper refrigerant levels. Refrigerant levels must be precisely measured and filled according to manufacturer specifications. Too much or too little refrigerant can impact system efficiency, leading to higher energy bills and potential compressor failure. An experienced HVAC technician will ensure that refrigerant levels are properly balanced.
5. Ignoring Proper Insulation and Sealing
A poorly insulated home can cause your AC system to work harder than necessary. Ensuring that doors, windows, and ducts are well-sealed helps maintain a consistent indoor temperature, reducing strain on your system and lowering energy costs.
6. Neglecting Proper Drainage
Your AC unit produces condensation that needs to be properly drained. If the drainage system is installed incorrectly or becomes clogged, it can lead to water damage, mold growth, and system failure. Checking and maintaining the condensate drain line is a key part of a professional installation.
7. Skipping the Thermostat Calibration
Incorrect thermostat placement or calibration is another common AC installation mistake that can cause inaccurate temperature readings, leading to inefficient cooling cycles. Avoid placing the thermostat near heat sources such as windows, lamps, or kitchens. A properly calibrated and correctly located thermostat ensures optimal system performance.
8. Not Testing the System After Installation
Failing to test the system post-installation is a common mistake. A professional installer will run thorough tests, checking airflow, refrigerant levels, and overall system operation before finalizing the job. This step ensures everything is functioning correctly from the start.
9. Attempting a DIY Installation
While DIY projects can save money upfront, attempting an AC installation without proper knowledge and tools can lead to costly AC installation mistakes. A professional HVAC technician understands the necessary permits, codes, and technical details required for a safe and efficient installation.
10. Hiring an Inexperienced or Unlicensed Contractor
Choosing the wrong contractor can lead to improper installation and long-term issues. When selecting an HVAC company in St. Louis, look for licensed, experienced professionals like Galmiche & Sons that follows a strict air conditioner installation guide and process to ensure a quality installation backed by expertise and excellent service.
