What to Know: St. Louis HVAC Issues to Leave to the Experts

July 4, 2017


Some minor maintenance a homeowner can do themselves, but most HVAC issues should be left to an experienced technician.

AC Repair St. Louis

There are some parts of your HVAC system that you can fix yourself. For instance, changing an air filter yourself is pretty simple. However, some tasks could be potentially dangerous, so it’s important to know which tasks you can safely undertake yourself and which you need to leave to the professionals.

Electrical Problems

HVAC systems conduct high amounts of electricity. An unqualified person who tries to fix electrical issues, is putting themselves at risk of being electrocuted. And not only can this person personally dangerous, it can also damage your system if you meddle with it. If you have any concerns that your HVAC system has developed an electrical issue, it is very important to call an experienced St. Louis HVAC technician.

Keeping the Unit Clean Outside

One job you can do, that could save you time and money later, is to ensure that the outside unit is free from debris such as twigs and leaves. Sweeping your yard regularly is a great habit to get into.

Cleaning the Coil Fins

While cleaning the coil fins may seem like an easy job, these fins are incredibly delicate. Your HVAC technician will have just the right tools to do the job properly.

Part Replacement

It can be tempting to order a cheap part online and attempt to fit it yourself. However, be wary of buying cheap parts online, they may not be up to standard and could be potentially dangerous. Additionally, failure to fit a part correctly could cause an even bigger problem down the line.

Changing the Air Filter

This is a job that you can do, and you should do it regularly. At least once every three months, and as often as once a month in the summer when the AC is running more often. A clogged air filter will make your HVAC system work harder. This puts a strain on the parts and also costs you more money when it comes to the electricity bill.

Handling Refrigerant

You must not attempt to handle refrigerant. It can cause a wide range of health problems. It can cause breathing problems if inhaled, and it can freeze your skin if touched. Don’t try to fix a refrigerant leak or top off the refrigerant levels. There are also regulations regarding the disposal of HVAC chemicals.

Checking the Fuse Box

Before you go to the expense of calling out a technician, do check the fuse box first. A blown fuse could be the reason your HVAC system has lost power. But, if the fuses blow regularly, then it’s wise to have this checked out as it could be a sign of an underlying problem.
