Homeowners today have the luxury of owning HVAC systems to improve the overall functionality of their homes. While it is nice to own such systems, they cannot perform well unless they are adequately maintained and repaired when necessary.

Below we can look at the most frequently asked questions about air conditioners to help you understand more about maintenance and repairs on your existing system. If you need maintenance or want to learn more about repairs on your HVAC unit, then be sure to contact us at True Climate Heat + Air.


If you have air coming out of your vents but it’s not cold, you should turn your thermostat off completely. One common problem we run into is that customers think they can keep their AC turned on when it’s not blowing out cold. This can cause your unit to freeze up in addition to causing potential further damage to whatever has gone wrong with your condenser. If our technician arrives and the unit is frozen, there isn’t much we can do until it thaws out, leaving you stranded in a hot home longer and having to reschedule your service call.


There are several factors that can cause airflow issues. Some helpful things you can do are to change your filters; a dirty filter can cause not only airflow restriction but also cause damage to your unit. Rinse off your outside condenser. Outside condensers can accumulate dust, dirt, and other debris that can restrict airflow. Keeping your condenser rinsed off and free of debris can help airflow and extend your condenser’s life. Have a licensed technician do an air balance. Sometimes doing some minor changes to the ductwork or adding some dampers can help with the airflow as well.


Some filters require change every month, however, some pleated filters can be changed once every 4 months. There are larger filters for allergy defenders that do not need to be changed but once every six months or every year. Suppose you have pets or issues with dust/allergies. In that case, it may be a good habit to change your filters more often than the suggested manufacturer’s guidelines but check your manufacturing guidelines or one of our knowledgeable technicians on recommended change.


The optimal range for indoor humidity is right around 35 percent relative humidity. If your home is within the 30 to 40 percent range, you should feel comfortable and experience no issues with higher humidity. Check for condensation inside the windows to know if your home has a relatively high humidity level. You definitely want to avoid this, as it can create an ideal growing environment for mold. If you notice condensation, adjust your thermostat to achieve lower humidity.
