At Infinite HVAC Services, our primary goal is to keep you comfortable by ensuring your HVAC system operates efficiently. By acquainting yourself with common HVAC terms, you’re empowered to:
Whether you need AC repair or an entire new air conditioner installation… understanding HVAC terminology serves multiple purposes. It allows you to:
- Choose the Right Unit: When you’re aware of terms like SEER (Seasonal Energy Efficiency Ratio) and BTU (British Thermal Unit), you can make an informed decision when purchasing a new AC or heating system. Higher SEER ratings signify better efficiency, while BTUs help you determine the system’s heating or cooling capacity.
- Communicate Effectively: When you can accurately describe the issue with your HVAC system, it becomes easier for professionals to diagnose and fix the problem. Whether it’s a faulty evaporator coil or a malfunctioning controller, knowing the terminology helps.
- Preventative Maintenance for HVAC Systems: Regular maintenance is key to avoiding major HVAC issues. Understanding terms like ACH (Air Changes Per Hour) and AFUE (Annual Fuel Efficiency Ratio) can assist you in discussing maintenance needs with your HVAC technician.
Don’t get lost in the technical terms. Dive into our easy-to-understand HVAC glossary below, and always remember that our team is just a call away!
