I really appreciate the time he took to answer my questions and make sure I understood everything. I just want to say thank you, Chris, for all your help! I look forward to a great installation! I’m scheduled for tomorrow"

"CB Mechanical provided exceptional service. The staff provided a level of friendliness that made me feel as though my time spent on the repairs was time spent with old friends. Charlie provided a lot of detail to his work and even double checked the repairs before completing the job. I feel as though the quality and low pricing makes them a top choice for my household. I promise you wonâ t be disappointed!"

"Chris’s crew was outstanding. They cleaned our crawlspace and didn’t encapsulated it. They were placed ductwork where it was needed. The photographs are clear documentation of a home improvement. I think the cost was reasonable to high, but I have nothing to compare to. In the end, I am quite pleased. The dehumidifiers have lowered the humidity in the living space and eliminated a musty smell that had been present. I can recommend him with no reservation."

Heating and Air Conditioning questions, answered by experts

You can adjust uneven airflow in your home by adjusting the dampers on the vents. However, if the temperature feels consistent throughout the home, don’t worry too much about uneven airflow. Generally speaking, larger rooms should receive more airflow than smaller rooms, especially if they only have one vent.

Your central A/C unit should be professionally serviced and inspected at least once a year to ensure it operates properly and efficiently. This is best done before the peak cooling season. A full-service inspection by a qualified pro will typically include checking safety components for issues like carbon monoxide leaks, verifying cooling components and coolant levels, and inspecting electrical parts like fuses and wiring. Regular servicing enhances efficiency, mitigates potential problems, and maintains optimal performance. Because AC systems contain hazardous refrigerant, professional handling is essential.

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.
