Your HVAC system, also known as your heating, ventilation, and air-conditioning system, is responsible for the temperature and air quality of your home. It's extremely important to maintain if you want your home to be clean and comfortable. Here are some common signs that indicate you need an HVAC repair.
  

Your Air Conditioner Blows Hot Air

Your air conditioner (AC) is for more than decoration. If it isn't blowing out cool, refreshing air, this is a sign you may need AC repairs. Call a technician to inspect it for you.

Your Air Conditioner Has a Weak Flow

If the air is cool but barely coming out, that's not helpful in circulating cool air around your home. There are several potential causes of this problem, so once again, contacting a heating and air conditioning company to get a technician to your home is your best bet.

Your Thermostat Doesn't Work

Your thermostat is what communicates with your HVAC system. It's how your HVAC determines if it needs to be hotter or cooler. If your thermostat doesn't work, there's no way to control your heating and air conditioning. Start by checking the battery, but if that still doesn't work, it's indicative of a larger problem.

Your Utility Bills Are Unusually High

It's normal for your HVAC system to be responsible for a significant chunk of your energy and electricity bill, but if you notice a sudden uptick from its normal number, something is causing your HVAC system to work harder than normal. This can sometimes be a relatively easy fix. According to the U.S. Department of Energy, replacing a dirty filter with a clean one can reduce your AC's energy consumption by 5% to 15%. If this doesn't work, you may need some sort of HVAC repair from a professional.

Your House Is Too Humid

As previously stated, your HVAC system is responsible for air quality. If the air in your home feels sticky, stuffy, and just plain uncomfortable, something is wrong with your HVAC system. Calling a professional for an HVAC repair will be the best course of action.
