Having Properly Sized Duct Work will Lower Operating Costs and Provide Greater Comfort

Duct Work

We Offer Manual D Ducting Calculations on a room to room basis. This will allow proper air flow for your unit’s heating and cooling functions. A Manual D is the procedure recognized by the American National Standards Institute (ANSI) and is specifically required by residential building codes. Air is the first word in air conditioning.

Duct Balancing-
This is measuring your home’s airflow, using a velometer and damper equipment. HVAC Air Balancing benefits include: enhanced heating and cooling performance, lower operating costs, and greater comfort. When properly balanced, HVAC systems will minimize their energy usage, operational costs and ensure your home is pressurized accurately.

Duct Testing-
We use a Duct-Blaster that tests for any air leaks and deficiencies, due to poorly insulated duct. This also confirms the Static Pressure Testing of your system; which manufacturers require after installation of new HVAC equipment. Measuring static pressure is a fundamental part of diagnosing how a duct system is performing. It’s kind of like getting your blood pressure tested when you go to the doctor.

Tri-County provides excellent service. We’ve worked with both Pete and Dustin and highly recommend both. We are renting our home and have had problems with our air conditioning since we moved in over a year ago. Another company came out and told us everything was fine and that we just needed to adjust our thermostats, but that didn’t work. Tri-County came out and discovered the real problems (which included fried wires and a broken duct), even took photos to show us the problems, and then took their time to fix them. We really appreciated their expertise, thoroughness, and commitment to doing a good job.Jacqueline N. Round Rock, TX, Yelp Review
