Industry Definitions:


Annual Fuel Utilization Efficiency - Measures heating equipment efficiency in converting energy by projecting the average thermal efficiency for a heating season. Higher AFUE ratings means greater efficiency.


Air Conditioning, Heating and Refrigeration Institute.


The American Society of Heating, Refrigerating and Air Conditioner Engineers.


British Thermal Unit - The amount of energy required to cool or heat one pound of water one degree Fahrenheit.


Cubic Feet/Minute - A volume of airflow measurement.


Coefficient of Performance - An efficiency calculation comparing the heating or cooling provided to work required. The higher the COPs, the more efficient the system.


Energy Efficiency Ratio - Measures the cooling capacity at one condition. Cooling Capacity (Btu/h)   /   Input Power (watts)


High Efficiency Particulate Arresting - Filters which meet strict standards of efficiency set by the US Department of Energy.


Indoor Air Quality - Smoke, dust, allergens, etc., all affect indoor air quality.  It is important to use a whole-house air cleaner to clean the air you breathe.


Minimum Efficiency Report Value - A rating used to measure the effectiveness of air filters. The higher the MERV rating the more effective the filter. The key to choosing the correct filter is to balance indoor air quality and system required air flow.


Seasonal Energy Efficiency Ratio - A measurement similar to MPG for vehicles.  It is the amount of cooling produced divided by the amount of electricity used. For more information, check out our blog on SEER.

Answers to Common Questions:

Q: Can I get a quote for a new system over the phone?

A: To ensure you have the most appropriate cooling and heating system, our Comfort Advisors take many measurements to calculate the proper tonnage your new system should have. One of our Comfort Advisors would be happy to provide you a comprehensive quote. Contact us if you would like your free estimate.


Q: Why does tonnage matter?

A: Tonnage measures the amount of air an air handler moves. It is important to have the appropriate tonnage in an air conditioner for your unit to work efficiently and properly. If the system's tonnage is too much for a home, the unit short cycles and won’t remove humidity.  If the tonnage is too little, meaning the unit is too small for a home, it won’t cool the home and the system will continue running causing high energy bills. Our Comfort Advisors will look at all the specs of your home and design a system specifically for your home’s size and heat output.


Q: What are some important factors to consider when purchasing an air conditioner?

A: SEER rating, manufacturer's reputation, manufacturer's warranty, installing company's reputation, correct equipment sizing, permitting.


Q: What can I expect from my new HVAC system?

A: You can expect to have better efficiency, quieter operation, better comfort, more convenience, shorter lifespan. For more information, watch this video: What to Expect from Your new A/C System


Q: Why does my system need annual maintenance?

A: To ensure you get the best efficiency out of your air conditioning system, it is important to have it maintained at least annually. If your unit is not properly maintained, it could lose 5% of operating efficiency every year because of debris build up which obstructs airflow.

Q: Why are some A/C service calls so expensive?

A: Warranties are limited and equipment is built with efficiency in mind, not durability. For more information, watch these videos: Why Some A/C Service Calls Are so Expensive and Manufacturers' Limited Parts Warranties Explained


Q: What is the Gap Protection Plan?

A: There are many gaps embedded within manufacturers’ warranties, and some of those gaps are: unreimbursed parts and supplies, refrigerant, 2nd trip to install OEM part, non-part calls, processing fees, shipping and handling for parts, and others. If any of these issues were to occur in your air conditioner unit, then you are liable to pay for those damages. The Labor Gap Protection Plan that Tri County Air offers potentially saves you from paying hundreds of dollars. For more information, watch this video: Local A/C Company Stands in the Gap for You
