The reason your HVAC system may not be working could be a number of things. Always make sure to take the necessary steps to keep your system running properly. Here are some common reasons and steps you can take to make sure your HVAC system runs properly always
Uneven heating and cooling is a common problem with heating and air conditioning systems. Some rooms are nice and warm in the winter, others are chilly. Some rooms get comfortably cool in the summer, others are stuffy. Air flow has a lot to do with this problem. Dirty filters, closed vents, and ductwork issues can impede air flow, causing uneven heating and cooling. Home insulation is also a factor. Make sure to check or replace filters and make sure all the vents are clean and open.
If you see enough dirt and debris on the air filter to fill a moon crater, you need to replace it. Or clean it if it is the washable kind. Filters should be replaced about once a month, depending on the system you have. If you don’t you’re making your system work harder than necessary. Also, check the heat exchanger and coils for any dirt.
If there is water coming from the indoor unit of your HVAC system, you need to correct it as soon as possible to avoid water damage to your home. Water around the indoor unit means your system is leaking, not draining properly, or making excess condensation. Condensation can form on the evaporator coil and suction line if they are not properly insulated. If the necessary insulation is missing or leaving part of the coil or line exposed, more condensation collects on it, which can drip onto the floor. In some situations the coil may ice up, and when the ice melts it will leave a puddle on the floor. If the condensation drain is blocked it can cause pooled water. In the worst case, your system could be leaking refrigerant. Both air conditioners and furnaces can leak water.
Another way you can track your HVAC systems issues it with your utility bill. Utility rates adjust often. If rates have remained steady while your bill has increased, you may have an issue that needs to be addressed. For AC systems, the federal government increased minimum efficiency ratings in 2006. If your system is older than that, it may be another reason for your higher energy bills.
There are other things that can cause your HVAC system to run poorly. These are some of the most common and taking he steps provided will help you along the way.
