Q: Should supply air be equal to return air?

• <div><p>Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.</p></div>

Q: Do HVAC zoning systems save energy?

• <div><p>Yes, HVAC zoning systems offer energy savings by allowing precise temperature control in different zones in your home. Rather than conditioning the whole house uniformly, these systems direct airflow where needed, preventing energy waste. Tailoring comfort to specific areas reduces energy consumption and lowers utility costs, making HVAC zoning an energy-efficient choice.</p></div>

Q: Can a frozen AC unit cause damage to the system?

• <div><p>If left untreated, a frozen AC unit can lead to costly damage, especially to the compressor and evaporator coils. When ice forms on the evaporator coils, they become brittle and more susceptible to breaking. Plus, a freeze makes your AC system much less efficient, which means it's wasting energy and costing you more in your monthly energy bills.</p></div>

Q: Do services include refrigerant checks?

• <div><p>Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.</p></div>

Q: Should a whole house dehumidifier run all the time?

• <div><p>You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.</p></div>

"J & J Air, installed our new Trane system a couple of years ago and did a wonderful job. Installation went very well, on a terribly hot day, the team did a great job, with no mess left behind. We have had a couple of Mechanical issues 1 with a broken part, and 1 with a failed switch. Both times the J & J teams showed up on time and resolved the issues as needed. Jeremy and his team are to be commended for their efforts and their Customer Service."

After looking the room over as well as the old A/C he worked up a price for a new system. The price was very reasonable and Tommy explained the payment plan in every detail.
