What to Expect From a Professional AC Installation

In order for your air conditioner to work efficiently, it must be installed correctly. Professional AC installation by a skilled technician is done in a way that ensures your system reaches top efficiency.

Here’s what you can expect when you choose Sherlock for your Oceanside AC installation service:

  • Accurate sizing: An undersized air conditioner can’t meet your demand for cooling on the hottest days. To avoid this situation, some careless technicians deliberately oversize their systems, which causes temperature swings, humidity problems and excess component wear. A competent HVAC technician uses the Air Conditioning Contractors of America’s (ACCA’s) Manual J to accurately size every system they install. This requires collecting detailed information about the house, such as the number and size of the windows.
  • Recommendations for improving your ductwork: Ducts that aren’t properly air sealed leak conditioned air and uninsulated ducts waste energy. Both these problems compromise your whole cooling system’s efficiency. Before your system is installed, your technician will inspect your ducts. If necessary, the technician will use mastic or metal-backed tape to seal the duct joints and add duct wrap or other duct insulation. Your technician might also make upgrade recommendations, such as reconstructing parts of the duct system to reduce sharp corners that slow airflow.
  • Airflow assessment: Your air conditioner was manufactured for a specific rate of airflow. Too little airflow means you won’t get enough cool air and your system will run less efficiently. Insufficient airflow can also cause your evaporator coil to freeze, which can damage the evaporator and the compressor. With too much airflow, however, you could end up with temperature swings. After a professional AC installation, your technician will measure for the correct airflow.
  • Measurement of the refrigerant charge: Both a high and low refrigerant charge can impair your system’s efficiency. Low refrigerant will limit the system’s cooling capacity. Too much can lead to refrigerant entering the moving parts of your compressor, possibly destroying this component. For this reason, your technician will test the refrigerant charge after the system is installed.

We Offer HVAC Maintenance Plans for Your Convenience

As a rule, you need to maintain your air conditioner each spring, and your heater in the fall. This will help ensure the systems are functional for when you need them the most. Having your air conditioner break down during the hot summer season, or your heater malfunction during winter, is frustrating. Our team will provide routine maintenance to keep your systems running all year long.

Benefits of regular HVAC maintenance include:

  • Longer-lasting system
  • Improved indoor air quality
  • Better energy efficiency
  • Lower utility bills

Our Oceanside HVAC team will check for signs of wear and tear, and will replace necessary components. Regular heating and air conditioning maintenance will also help protect the quality of your indoor air supply, keeping you safe from allergies and other respiratory conditions caused by poor indoor air quality.

We make maintenance simple.
