HVAC systems are appliances that require regular maintenance. If you often miss your biannual HVAC routine maintenance then you may encounter issues more often than not. Some of these issues may be small which you can easily resolve using DIY solutions. Other more severe problems, however, will require professional intervention. So, unless you take proper care and precautions, you will have some problems with your residential HVAC systems.

Here in this article, we will look at the 5 most common HVAC problems. We will also look at the most feasible solutions to these problems so that we need not experience temperature swings.

Top 5 Problems Reported With Residential HVAC Systems

The following are the five most commonly reported problems with an HVAC system at home.

Clogged or Dirty Filter

Cleaning or replacing the air filter is the most basic maintenance routine that you must perform. It is also the easiest one. If you do not clean or replace the air filter at regular intervals, dust and dirt will accumulate. This will clog your HVAC system and can block the airflow in the system. This can cause the system to work much harder than usual. It can also sometimes cause the unit to overheat and eventually shut down.

This indicates that cleaning or replacing your HVAC unit’s air filter at regular intervals is pretty important. It can adversely affect both, the lifespan of your unit as well as your energy bills.

It is advisable to replace your HVAC filter once in about 90 days. Doing so will extend the life of your HVAC or air conditioning system, allowing you to breathe freely.

Your System Becomes Unusually Loud

Though it is common for your HVAC system to make subtle sounds, unusual noises from the system often point to some mechanical issue. It can be either an issue with the motor or some of its noisy pieces that need mending or replacing. Dirty burners or issues with the compressor or airflow can also result in weird noises. Whatever be the cause, it is not something that you can resolve by yourselves. You’ll need a technician who is an expert in handling HVAC and air conditioning repairs.

So, in case you start hearing squealing, screeching or rattling noises from your system, take it as a sign to call an HVAC expert.

Malfunctioning Thermostat

The thermostat is the component through which you interact with your HVAC system. It lets you control the entire HVAC system and control the climate in your house. So if your thermostat begins to malfunction, it will affect the functioning of the entire system. Often the issue can be with how your thermostat is set. In that case, you can first refer to your HVAC’s owner manual and review the instructions. And if that’s not the issue, you may then need to reach out to a technician. In case you have got a programmable thermostat, you might also need to check if the batteries need to be replaced.

This tells us that a malfunctioning thermostat will require an intervention from a skilled technician unless the issue is purely superficial.

Tips: A programmable thermostat can sense the outdoor temperature and adjust the indoor temperature accordingly. So, installing a programmable thermostat can be beneficial in terms of the energy efficiency of your system. For those with a manual thermostat, it is advisable to set the temperature 10 degrees lower. This keeps your system operating regularly and can save you a handsome amount in your monthly energy bills.

A Constantly Running Blower

There are several reasons behind the furnace blower running continuously. One of those reasons can be the thermostat being set to the ‘fan-on’ position. When this happens the motor will run continuously and so will the blower. This often happens if you have accidentally switched the fan switch to on.

Another reason behind this problem can be when the safeties or limits on the furnace of your HVAC do not reset. The fan relay is one of these limits on the furnace that turns the blower on when the furnace activates the heat. So if the fan relay sticks, the blower will not shut off.

A trusted HVAC or air conditioning contractor can resolve the problem after assessing the cause of your constant-running blower.

Water Leaks from the Unit

Every HVAC system produces condensation while in use. Usually, drain pipes ensure proper drainage of the water from this condensation. But your unit can leak water if the drain lines are either clogged or damaged. You can resolve the issue of a blocked drain pipe by pouring bleach down the drain. However, there can be other sources of the leakage as well. These sources can include the collector box or the heat exchanger. So, you might need the help of a trained professional who can determine the source of the leakage and carry out the necessary repairs.
