Installing the Right HVAC System

When it comes to choosing a new HVAC system, make sure you include size as one of your deciding factors. A system that’s too large or too small can reduce comfort, increase energy costs and shorten the lifespan of your equipment. Here are some potential drawbacks of each option:

An HVAC system that’s too large:

• Turns on and off frequently because it reaches the desired temperature too quickly (known as “short cycling”)
• Requires more energy because of the constant starts and stops (similar to driving in stop-and-go traffic instead of cruising steadily)
• Causes drafts and noisy airflow because of excessive air pressure
  

An HVAC system that’s too small:

• Runs for long periods of time to keep up with demand
• Places extra strain on the equipment
• Struggles to maintain consistent temperatures
  

The goal is to install an HVAC system that’s sized specifically for your home. Instead of relying on general estimates, an HVAC professional should perform a load calculation that considers your home’s size, layout, insulation and other factors. A properly sized system will operate more efficiently, maintain consistent comfort and help lower utility costs while extending the life of your equipment.
