Heating and Air Conditioning questions, answered by experts

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.

If you’re planning an AC replacement, choosing an AC with a higher SEER rating may save you money in the long run. Tax credits could cover as much as 30% of the job, and you’ll notice smaller utility bills (particularly if you live in a hot climate where you need to constantly run the AC). Generally, you can expect to pay between $350 and $1,500 for each SEER rating increase. Weigh the cost against your typical utility bill to figure out what’s worth it to you.

You should use a breathable, weather-resistant cover with ventilation. It can be a top cover or a full cover that has mesh to allow airflow. A full, non-breathable cover can cause moisture to build up, leading to rust, frozen parts, and corrosion. A full cover also attracts unwanted critters, such as mice, that can damage the wiring and your unit. If you need to protect your AC unit from falling icicles, choose a sturdy top cover or piece of wood that prevents icicles from damaging your unit.

Signs that your A/C system needs professional service include increased energy bills, uneven or poor cooling, loud or unusual noises, and frequent cycling.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.
