When it comes to heating and air conditioning, bigger isn’t always better. At SRI Energy, we take a whole-home, building science-based approach to help homeowners across Tulsa and the surrounding areas choose systems that are properly sized, energy-efficient, and cost-effective.
Oversized HVAC units are a common issue. They may seem like a good idea, especially in Oklahoma’s hot summers and chilly winters, but they often do more harm than good. An oversized unit will short cycle—turning on and off frequently—which leads to higher energy bills, excess humidity, and uneven temperatures.
Undersized systems aren’t the solution either. They struggle to keep up with your comfort needs and run longer than necessary, resulting in energy waste and more wear and tear over time.
The efficiency of air conditioners is measured by SEER (Seasonal Energy Efficiency Ratio), and furnaces are rated by AFUE (Annual Fuel Utilization Efficiency). A higher SEER or AFUE rating means better energy performance and lower utility bills. But even a high-efficiency system won’t work properly if it’s not the right size for your home.
Up to 35% of a furnace’s energy output can be lost through ducts located in attics, garages, or unconditioned spaces. That’s why our team recommends a proper Manual D ductwork calculation and design. Efficient duct layout and sealing go hand-in-hand with a right-sized HVAC unit to improve performance and comfort.
Getting the correct HVAC size requires more than just square footage. SRI Energy recommends a professional load calculation using Manual J standards to determine the actual heating and cooling needs of your home. This includes window performance, insulation levels, air infiltration, and more.
In many cases, homes that have undergone energy upgrades—such as air sealing and insulation improvements—may need smaller HVAC systems than originally thought.
We also offer blower door testing and air sealing services to help improve your home’s performance. These services reduce leaks and drafts, helping your system work more efficiently and keeping you comfortable all year long.
Whether you’re in Tulsa, Jenks, Broken Arrow, Bixby, Owasso, Sapulpa, or Sand Springs, SRI Energy is here to help you make informed decisions about your HVAC system. Our team takes the guesswork out of sizing and connects you with trusted local contractors who understand the science behind home performance.
Don’t let an oversized or inefficient HVAC system cost you more than it should. Book your home energy assessment with our Home Performance Professionals and learn how the right-sized system can improve comfort and reduce energy bills.
