"Mark and Corey were both very prompt, courteous, and professional. They presented fair pricing and superior installation on the 2 (two) HVAC systems that they supplied for my wife and I . They went the extra mile with them showing up to complete the install prior to a Hurricane headed directly at our area. I highly recommend Sensible Air Solutions for all of your needs, whether it be a full HVAC installation or HVAC service/repairs."

Heating and Air Conditioning questions, answered by experts

Modern AC leak sealants work as a temporary measure to stop refrigerant leaks. You can purchase them at most home improvement stores or on online. When using an AC leak sealant, keep in mind that it’s only a temporary solution, so you’ll still need to hire a pro to install a replacement part as soon as possible.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

While all portable AC units will collect moisture as part of their cooling and dehumidifying process, whether and how often you need to drain them depends on what kind of unit you have and the natural humidity levels where you live. For example, if you live in a very dry area and have a self-evaporating unit, you may not need to drain your portable AC very often at all. Some units may automatically drain collected moisture out the window through their exhaust vent.
