Getting Rid of Mice Stuck In Your HVAC System— And How To Keep Them Out!

We’ve all heard about the occasional mice issue, which isn’t quite out of the ordinary. They find access to certain areas in the house to keep them warm and sneak on our food storage. Their favorite places to hide are dark or small corners, like roofs, attics, air ducts, and vents.  Of course, if we can help it, we would prefer having no signs of these tiny animals pestering our living space. They grow in numbers incredibly fast, and it’s rather unhealthy to keep them hanging around. In this article, we’ll focus on the common identifying signs of mice present in HVAC systems, what are the ways to get rid of them, and how to keep them out.  

How to Identify Evidence of Mice Roaming In The HVAC System

  • Faint running sounds in the air ducts and ventilation lines
The usual first sign of mice infestation in the HVAC units, and probably in most corners of the house, are the faint sounds you can hear running around the ceiling and ventilation systems.
  • Clusters of mouse droppings (small, black, seed-like shapes)
Mice running around the house through the ventilation pipes often leave black droppings everywhere. You’ll notice their unique seed-like shapes, which are hard to miss.
  • Bitten chunks and corners in the cardboards, fabric, furniture, etc.
In their attempt to hunt for food around the house, you will notice bitten corners in food cabinets, closets, and boxes.  

How to Get Mice Infestations Out of Your HVAC Systems

It’s highly possible that mice infestations cluster in the ventilation lines of your heating and cooling systems. These areas are hard to reach for us, and they provide the most accessible routes for mice to transfer from one area to another. Follow these steps to get rid of the problem:
  • Turn off the heating and cooling system for your safety and to draw mice clusters out of the ventilation lines.
  • Open the exit points of the ventilation system.
  • Place snap traps with bait food on each exit point.
  • Get rid of the trapped mouse who takes the bait and replace it daily with a new snap trap.
  • Repeat the process until you observe that there’s no evidence left of the mice infestation around the house, specifically in the HVAC system.

How To Keep Mice Infestations From Coming Back

You can always hire a pest control unit to sweep your house from the natural mice infestations and other kinds of pests. On the other hand, here are a few suggestions on how you can prevent mice infestations from coming back to your HVAC systems.
  • Ensure that your HVAC systems are clean inside and out. Infected areas often attract as a livable condition for pests. Maintain a cleaning schedule with your trusted HVAC maintenance service providers.
  • No matter how big or small, seal all the possible entry points in your air duct, ventilation, and exhaust systems. Some leaks may require professional ductwork. Make sure that you regularly have your system checked twice or once a year. 
  • HVAC system repairs and refurbishments are extra precautionary measures you can periodically follow as well.

Final Thoughts

Install the right kind of flue pipes and vent covers that will secure your air duct system. Ultimately, proper maintenance of your HVAC systems will help prevent mice infestations from happening in the first place.  Find out the best HVAC solutions near you.

Life Cycle of HVAC Systems: How Long Do They Last?

Heating, ventilation, and air conditioning (HVAC) systems can last for a significant duration. To get the best value out of your unit, you need to become aware of the most common factors that affect their life cycle. When HVAC systems reach the end of their lifespan, it’s highly advisable to have them replaced rather than spend an endless routine of repairs and costly maintenance services to extend its functionality. Habitual malfunctions often indicate that your unit is about to retire, and it’s probably causing a high influx rate on your electricity bills. So, let’s go ahead and jump over it!

How long do HVAC units last?

There are different kinds of HVAC units. We’ll discuss each of their functions and their expected life cycle.  

Air Conditioner

Air conditioners are central heating and air systems that require occasional maintenance and regular cleaning. The part that you need to keep an eye on in an air conditioner unit is the compressor.  When it starts showing fluctuating failures, it either suggests a major repair or unit replacement. They usually last for an average of 15 to 20 years. However, frequent usage of air conditioners, especially in warm regions, will probably limit the lifespan of the system for only up to 15 years.


Furnaces also function as central heating and air systems with an average lifespan of 20 years, which is quite longer than air conditioners. Typically, furnace units demand standard maintenance methods to make them last as long as they should. The most important feature of furnaces is the heat exchanger. Once this function starts breaking down, you’re better off buying a new furnace than having your old unit repaired.  

Heat Pump

Heat pumps can function as a heating or cooling system. They can last for as short as 10 years, but their life cycle can be extended for 20 years. Based on experience, they often fall out quicker than air conditioners, particularly when used in areas bordering the water.  


Boilers are fuel-powered heating systems most suitable for places with harsh cold weather. They’re designed with old-school technology, but long as the heat exchanger remains working, they can last 20 to 35 years.  

Spit System

Split systems work like central heating and air conditioning for all kinds of weather. They can also serve as a pollutant or allergen prevention unit because it’s equipped with a filtration system. Constant use in coastal areas might cause split systems to last for only as short as 10 years. However, they’re initially designed to function for up to 30 years.  


Two primary factors that affect HVAC systems’ lifespan are (1) the frequency of usage and (2) amount of maintenance methods applied during their functional years. If you wish to extend your HVAC system’s life cycle, you need to invest in regular maintenance methods. By doing this, you can always keep efficiency at an optimal level.

5 Amazing No-Cost Tricks To Make An Air Conditioning Unit Be More Energy-Efficient

According to the Department Of Energy, heating and cooling make up half of the total utility expenses in a household in the United States. So it also follows that the AC unit constitutes the largest slice of the pie in terms of your monthly utility bill. If this is the case, then is there any way for us to save money while using our aircon? And to be more specific, are there any no-cost tricks to make your air conditioning unit more efficient? If you’re interested to know more then we invite you to read further as we are going to explore this topic in today’s entry.

Routine Cleaning Around The Outdoor Condenser Unit

Believe it or not, this part of your AC system is a magnet for dirt and debris. And if we tend to ignore it, then the dirt will build up over time and thus resulting in poor performance of your AC. So it’s very crucial to clean the outdoor unit of debris so that it will work efficiently. Of course, basic cleaning can be done as a DIY project, but more in-depth cleaning chores should be handled by a professional.

Increase The Thermostat By A Couple Of Degrees

adjusting thermostatTypically, adjusting your AC temperature to a couple of degrees up (or more) during summer (and a couple of degrees down during winter) does have a significant effect on your monthly energy consumption. And the good thing about this is that you can program this device to change the temperature at different periods of the day or during times when you’re going outside for several hours.

Use The Vacuum To Keep Indoor Vents Unblocked

Another no-cost trick to make your air conditioning unit more efficient is to remove dust and debris from the indoor vents using a vacuum cleaning. You may not be aware of this but dust buildup impedes the airflow of your AC system. So removing these impurities will help maintain a steady airflow and allow your cooling and heating appliance to operate more effectively than the usual.

Avoid Placing Lamps And Other Heat-Producing Devices Near The Thermostat

This is also necessary so that your thermostat will function properly as the presence of any heating appliances near this device will create a false reading. In short, it will only indicate that your home needs to be cooled even more and run longer (and work harder) than it’s supposed to.

Avoid Using Your Oven And Dryer During The Hottest Time Of The Day

And finally, your air conditioning unit can be more energy-efficient just by changing the time when you are using the oven or dryer. To be specific, running these appliances will only produce warm air. And as a result, your AC system will have to work harder just to create a desirable temperature for your home.

How To Troubleshoot Your Air Conditioner Thermostat?

The thermostat is a primary component of your air conditioner. And if something went wrong or if it’s not installed properly, then chances are this device would not function the way it’s intended to be. However, not all thermostat issues require the help of a technician for there are some troubleshooting steps that you can do on your own before calling an HVAC expert. So read more as we are going to share some DIY information on how to troubleshoot your air conditioner thermostat in today’s guide.  

Things That You Need To Check When Performing A Thermostat Troubleshooting Process

Before considering the services of a professional, you need to check on these things first:

Is The Device Receiving Power?

If the air conditioner thermostat is always shutting down or the backlight keeps turning off, the first thing you need to do is to check if the device is receiving enough power. Thermostats are powered by batteries and your AC itself. So you need to ensure that there is enough power coming from these sources. Likewise, you also need to check if the circuit breaker has tripped, which also causes the device and the whole air conditioning unit to lose power. We also recommend that you change the batteries and replace them with a fresh set.

Is The Thermostat Situated Near Sources Of Warm And Cold Air?thermostat installation

If the device is installed in very cold or warm areas, then it won’t be able to make an accurate reading of the temperature in your home. And as a result, it won’t be able to activate when cooled air is needed inside the house. So make it a point that the thermostat is installed in areas away from windows, vents, direct sunlight, and any other factors that might influence the temperature around the house.

Is The Device Properly Mounted On The Wall?

Proper installation is also necessary for the device to function well. If not, then it will only give you faulty readings which can then result in waste of energy (as reflected in your monthly electric bill). So try to use a bubble level and check if the thermostat is properly mounted on the wall. Also, make sure that it is installed at least 5 feet from the floor to ensure accurate readings at all times.

Is The Thermostat Dirty?

And one last thing that you need to check is if the AC is dirty because any dirt buildup in your cooling system can also cause the air conditioner thermostat to malfunction. So clean up your AC unit by opening the cover and remove any dirt that you can find.

The 5 Features Of Environment-Friendly HVAC Units

In recent years, technology has made it possible to develop products and process that are not harmful to the environment. And with this in mind, the AC industry is no exception to these innovations as eco-friendly air conditioners are becoming widespread in use and manufacturers are phasing out the use of ozone-depleting refrigerants to give way for “clean and green” alternatives without compromising convenience. Read more as we are going to tackle the 5 features of environment-friendly HVAC units in today’s entry.

Size Does Matter

This may come as no surprise but the size of the AC unit does play a role in its eco-friendliness. And the reason for this is that experts have found out that some people just install HVAC units without really considering the size of their homes. Now if a wrong size of AC is installed, it will consume more energy to cool down the house, which will then produce more carbon emissions into the air (since most ACs are run by fossil fuels such as coal) and harming the environment in the process. Good thing manufacturers have found a way to maintain this balance by producing AC systems in different sizes to suit the needs of every home or establishment.

Customized Matched Systems

In order to achieve optimal energy efficiency, some environment-friendly HVAC units make use of different energy sources for heating and cooling. In other words, AC companies have developed modern ways to customize each part of the AC system from the indoor coils to the thermostat to meet the individual heating & cooling needs of every household.

2-Stage Compressors

Nowadays, air conditioners have 2-stage compressors to automatically compress more during hot days and less during cooler days to save more on energy.

Geothermal Heat Pumps

This innovation makes use of the earth as a natural heat-sink so the AC can capitalize on the flow of warm air for a certain area and convert it into cooled air. This feature has made eco-friendly ACs up to 40% more energy efficient compared to its predecessor units.

Smart (Programmable) Thermostats

Lastly, the introduction of home automation has also made it possible for environment-friendly HVAC units to use smart thermostats to automatically set the unit remotely so the entire house will be already cooled by the time you go home. This simple advancement is by far the most effective feature since it prevents the appliance from exerting too much effort in producing cooled air as the device can automatically turn off the AC when the room has reached the appropriate temperature.

The 5 Most Important Air Conditioning Components

In 1902, the first electrical air conditioning systems was invented by Willis Carrier, a well-known pioneer in the air conditioning industry. Now, the air conditioner or “air con” as colloquially called is one of household appliance that we can’t live without. Yet, most of us still wonder how it produces cooled air and eliminates the heat off from your house. If you are one of the many people who are interested to know more about the working of the air conditioner, then we suggest that you continue reading as we are going to share the 5 most important AC components that make this appliance function for the production of cooled air.


The blower facilitates the air flow so that it can distribute cooled air in your household. Likewise, this part is also responsible for working with your furnace and pulls the room temperature air to the machine for re-cooling.


As previously mentioned, the air conditioning appliance takes the warm air inside the house and disperse it outside. With that being said, the compressor is also considered as one of the essential AC components since it assists in the entire cooling process of the appliance by converting gas particles in the air into liquid. Likewise, it enables the refrigerant chemical to flow continuously. The refrigerant absorbs room temperature air inside your home and sends it into the compressor through the suction line. The compressor will then squeeze the air very tightly to produce gas which then causes the molecules to increase gas’ temperature. So in other words, the compressor is the one responsible for converting the low-pressure gas into a high-pressure state. The high-pressure gas will then go into the condenser to be cooled and converted into liquid.

Condenserair conditioner parts

This is the second most important part of the air conditioning appliance as it cools down the gas, converts it into a liquid, and helps the heat to escape inside the house. The condenser can be easily recognized as it somewhat similar to a car’s radiator in terms of appearance.

Expansion Valve

The expansion valve component is responsible for regulating the amount of refrigerant entering into the evaporator.


And finally, the thermostat is also considered as one of the crucial AC components since it indicates the desired level of cooled air inside a room. So basically, it’s the primary controlling mechanism of your appliance. The thermostat component also includes a sensor to notify the AC system to stop working for a while once it reaches the desired temperature and starts working again once the air temperature in the room begins to rise again.
