Even if you are handy and good at HVAC cleaning, there are some jobs that should only be handled by licensed contractors. That is, while might be easy to clean and maintain most components in a central HVAC system, you often need a professional touch to make more significant repairs to the most complicated components in your system. This article explains two important jobs that you should have professional HVAC technicians do to make sure your system is running as efficiently as possible.
Recharging the Refrigerant Lines
The refrigerant lines are obviously key to the creation of cold air when your air conditioning is running. Basically, the refrigerant lines connect the AC unit to the air handler and evaporator. When your refrigerant lines are properly calibrated, they help cool down air as it passes by the evaporator. So, smart homeowners will have professionals come check and recharge their refrigerant lines once every couple of years.
There are a few ways you can tell if your refrigerant lines need to be recharged. First of all, if it just seems like the air is not as cold as it should be, it could definitely be an issue with the refrigerant. Additionally, if the air does seem like it is as cold as it should be, but you notice a spike in your utility bills, this could also mean that your refrigerant lines are not properly charged. Professionals have the tools and knowledge to repair and recharge refrigerant lines very easily.
Checking the Gas Lines
You also want to have professionals check your gas lines. Messing with gas is never something you should do yourself. The flow of gas through the lines is more closely associated with the heating elements in your HVAC system. So, if you've noticed that your heating system is not as efficient as you think it should be, this is one thing that you should have professionals check out. If a gas line needs to be replaced or repaired, it can be easily handled by a licensed technician.
It could be nearly impossible to diagnose gas and refrigerant problem yourself if you don't have the right training. Often, a professional service call will result in the diagnoses of a serious problem that can be immediately fixed. In some cases, you might need to replace a major part of appliance.
Ultimately, the health of your HVAC system depends on regular personal maintenance and cleaning, but also professional heating contractor services.
