Having the Right Sized AC System Will Improve Performance and Energy Use
If you’ve decided to upgrade your air conditioner this spring, it’s fine to start exploring on your own. However, when you’re serious about making a purchase, it’s important to work with an HVAC professional to size your system, ensure a warranty and perform maintenance tasks.
Sizing
Many variables come into play when choosing an air conditioner. Sizing in particular is important, and HVAC professionals use a tool called Manual J to perform a heating and cooling load calculation. This calculation takes into consideration:
- The square footage of your home
- Amount of insulation
- Number, quality and orientation of the windows
- Appliances that emit heat
- Outdoor landscaping factors
- Climatic considerations
- Air infiltration inside your home
- Lifestyle habits
- Personal temperature preferences
Sizing problems
The calculation is all important, as it helps avoid selecting the wrong size equipment. If you upgrade your air conditioner with a system that’s too large, you’ll notice that the humidity levels indoors will become higher, because the system will run for short periods of time.
Additionally, short cycling limits the filter’s capabilities, when compared to smaller systems that run longer and with less on/off cycling. Frequent cycling consumes more electricity and causes further wear and tear on the parts inside the air conditioner, increasing repairs and reducing system life.
Warranty
Reputable manufacturers of air conditioners provide warranties for parts and labor. The HVAC contractor who installs the equipment honors the manufacturer’s warranty, and guarantees the installation. If you sidestep a qualified dealer when you upgrade your air conditioner, you lose these benefits, which can amount to high costs for repair and parts in the future.
Maintenance
HVAC technicians also show you how to maintain your equipment. Some of the tasks you can perform yourself, and others need to be done by the HVAC technician to keep the warranty valid and your system running efficiently. Your contractor keeps precise records about the maintenance and condition of the appliance, which helps troubleshoot any issues that could occur in the future.
