How to Fix 6 Common HVAC Problems

Common HVAC Problems

HVACs are very sturdy appliances. 

However, this does not mean that you can avoid or push its maintenance to a later date. 

That said, it’s very difficult to carry out DIY cleaning and repair on certain HVAC parts as they are very complicated machines.

If your area hits high temperatures and your HVAC suddenly stops working, it might become unbearable to even sit indoors. 

So regular HVAC maintenance is crucial!

You can always get in touch with HVAC repair services in Baltimore and nearby areas for more complicated problems.

Meanwhile, let’s take a look at some common problems and ways to fix them.

Here are six common HVAC problems and solutions to fix them

The most common HVAC issues are related to ventilation, air conditioning, and irregular heating patterns. 

They occur due to a failure of different parts of the system. 

1. Unusual HVAC Noises 

A whining or squealing noise from the motor can be an indication of HVAC issues. 

Replacement of the motor may be required to avoid HVAC failure. 

You can’t ignore these signs as they may be a warning of a dangerous operating condition or can even lead to HVAC failure.

2. Dirty Filters 

Dirty filters are the most common problem of an HVAC. 

With the HVAC working round-the-clock, dirt and debris tend to build upon the filters. 

If you don’t change it or clean it regularly, then the old filters can block airflow which makes it harder for the HVAC system to heat your home. 

This will lead to mechanical and electrical parts going bad sooner than they should.

The standard procedure for changing air filters is to do it every one to two months if it is in constant use. 

When not in use, you can change it every three to six months.

3. Thermostat Problems

If your HVAC system is constantly turning on and off or not turning on at all, then it could be your thermostat that is causing problems. 

You need the thermostat in a good working condition to keep your home at the desired temperature. 

Sometimes all you’ll need are new batteries or sensor!

If you happen to have an outdated thermostat, try upgrading it to a newer model. 

4. Airflow to Your Condenser Unit

At times, there may be debris on the outside of the unit that may be blocking airflow. 

On the other hand, tall plants or weeds grow too tall and are too close to the condenser that partially or completely blocks the airflow. 

Trim them back or remove them completely to help the air flow in and out efficiently.

5. Leaking or Blocked Ducts 

The dirt and dust accumulate in the ductwork. 

Ducts that are really narrow can become easily clogged. 

In certain cases, there can be rodents, birds or insects that build nests in HVAC ducts. This leads to airflow and blockage issues.

You should ideally get the entire ductwork inspected once in six months. 

6. Mechanical Wear and Tear

Wear and tear is a big issue for your heating system. These include belts and bearings, which may result in overheating, poor heating, or airflow issues. 

Regular maintenance is a must. Oil the bearings and motors, if necessary.

Some other HVAC parts that you need to check are condenser coils, circuit breaker, pilot light, thermostat, and compressors. 

These are probably the most common problems you may face with your HVAC systems. 

While some can be taken care of on your own, most are quite complex to tackle them on an individual basis.

At times like these, it’s highly recommended to get in touch with a professional HVAC repair company in Baltimore or nearby areas.
