"The company was paid to diagnose and fix a leak to my roof. They determined that a small patch of roof needed to be replaced. A couple of weeks later the leak continued from the same spot in the ceiling. The tech again came out and claimed it was another leak in a different spot although the leak inside was in the exact same spot. They did not fix the problem the first time and wanted more money for this “new leak.”"

Heating and Air Conditioning questions, answered by experts

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.

AC capacitors typically last for a long time and many last for the life of the air conditioning unit. You can expect to get about 20 years out of an AC capacitor. When an AC capacitor suffers an untimely death, it’s usually due to overheating, a power surge, or a short circuit. You can prevent these events from happening and extend the life of an AC capacitor by getting regular AC maintenance every year.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

Unlike other types of air conditioning, portable units don’t require venting or any other associated parts like hoses. For that reason, they don’t function the same as their counterparts, but will do a similarly good job of cooling down small spaces and won’t require any installation or much maintenance.

No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building’s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners.
