HVAC Troubleshooting: When Should Replace My HVAC Blower?

Your HVAC (heating, ventilation, and air conditioning) system(s) are often the answer to your comfortable living.

In the colder months that are approaching, there is no doubt you are using your HVAC system for its ‘warm air’ setting. Thus you will want to remain warm throughout the winter, and to do so there is some troubleshooting that may need to be covered.

Many HVAC units are compact and have a simple design, these are regular designs that are found in houses and apartments. Larger buildings will have larger complex machines. Regular HVAC maintenance is required in order to ensure that the buildings in the unit do not break down and they are operating at maximum efficiency.

How To: Prevent AC Unit Faults in Winter

There are  a number things that can be done when taking precautions during the winter, so to prevent problems.

Ensure that your keep your units free from obstruction and make sure that your system doesn’t have to work harder than necessary – this can be applied to both indoor and outdoor units.

Similarly, ensure that nothing is blocking indoor vents or air discharge points enabling your system to run as smoothly as possible.

You will want to set your controllers to a reasonable temperature, keeping in mind the outdoor conditions. For an office, 23 degrees celsius is a sensible temperature, whereas 30 degrees celsius which is a common finding can put strain on the unit.

Preparing your AC Unit for Autumn

So, we’re finally into September meaning summer is officially over.

Right now, you may be thinking about what you will need to do now that the temperature is dropping and former long summer days are shortening.

Below, are some tips from BMS – one of the well-known Industrial Air Conditioning Companies in Midlands, which should maneuver around an AC Unit repair.

If you have a window AC unit, your only required maintenance is to take the unit from the window, ensure that it is clean – if not, clean it, and continue to clean the filters if necessary.

Regarding central units, you will need to replace your filters. Spend time looking for new filters and swapping them out with your old ones – this will save you money on repairing your air con. If you leave a dirty filter in the system, this is likely to lead to clogging later on as dirt particles will cling to the filter and build grime.

Ensure that you inspect you system thoroughly and that nothing is damaged is broken. Be sure to clean the outdoor HVAC unit, also.

After you have switched off the central AC unit, make sure that you cover it. To do this, you can use plastic or vinyl to protect it from the coming harsh elements.

Summer and your air conditioning unit

Getting your air conditioning unit ready for summer couldn’t be simpler with BMS Aircon’s tips!

Letting your AC Unit sit idle for a number of months will inevitably lead to it collecting dirt, dust and debris which could affect its performance when you need a cool down in the heat up ahead.

Clean/replace filters

Your initial step is to clean your filters or replace them, which should be reviewed twice, annually. Failure to do this will lead to a restricted air flow which will reduce its efficiency.

Clean condenser coils

Your central air conditioners’ condenser coil will typically be located outdoors. If debris has gotten inside the unit, it is likely that the coils will be clogged with dirt. To clean the coils, the top and side panels will need to be removed, then using a refrigerator coil brush or a soft brush on a vacuum, gently clean the coils from the outside of the unit. Use the vacuum to clean the insides of the coils.

Clear debris

Scoop out any debris and leaves from the base of the condenser and, if applicable, ensure the drain isn’t blocked.

Check coolant lines

Refrigerant tubes or pipes will typically have a roam coolant line insulation covering them to prevent the loss of energy. If there are any frayed areas, replace them by installing foam insulation sleeves, or wrap the lines with a foam insulation tape.


Ensure that you test your unit once it has fully dried and then turn off the power to the condenser back by turning the thermostat in your home off, then turning the power at both the main panel and disconnect box on, lastly, switch your thermostat to cool.

Saving Energy When Using Air Conditioning

As the weather eventually becomes warmer, using your air conditioning unit will be necessary.

In order for you to save energy while you’ll cooling off, we’ve listed a number of tips below for you to follow.

Night-time – In the late hours of the day, you will not require the AC Unit to work at full capacity – turn it down so it will be running less while you are sleeping.

Portable units and windows – Another great way to save energy is to invest in a portable cooler that will cool the room you are occupying. They use up to 50% less energy than a regular AC Unit.

Have your unit serviced – On some occasions, a quick maintenance check could be the only thing your AC Unit requires, however, many will benefit from a thorough cleaning.

Furniture rearrangement – Furniture placement actually plays a big role in potentially saving energy with air conditioning. If furniture proves to be an obstruction to any air conditioning vents, the back of a settee could be getting cooled rather than yourself.

78° – Running your AC Unit oat 78 degrees is a suitable level, similar to that of a car on cruise control. There is also the option of turning it another 5 degrees lower to save energy.

Home alone – When you are not home, attempt to turn the AC Unit to 85 with any windows and drapes securely shut. It may be warm when you return, however, the blinds/drapes will have kept out the sun as well as the heat not being so considerable thus the unit won’t have to work as hard to cool the air.

Use a fan – With air conditioning units being the go to, we are forgetting that fans also do a wonderful job of keeping you cool. Using them to circulate the cool air means that you will not require too much being pumped into the room, not only that but having them as a backup is a great idea as they use left energy!

Air conditioning benefits

The purpose of an air conditioning unit is to provide a comfortable environment to work in throughout the seasons.

Naturally, you would expect AC Units to possess many benefits because of their purpose. An AC Unit can have either of the two functions to heat or to cool. A majority of the newer models will have a smart changeover switch where you can set the temperature and the unit will swap from cooling or heating as needed, alone.

Another benefit is air purification; again, many modern units will have an anti-fungus filter which will catch any allergy-causing mites, smoke particular and odours that may be in the air.

We’ve approached summer and soon the outside air will begin to reach uncomfortable levels, your home will begin to become warmer than the outside temperature. When an AC Unit is installed, the temperature can quickly be reduced to much more comfortable level.

Air can be recirculated through the filters in the air conditioning unit and will trap any dust and pollen which is a great benefit for those that suffer from allergies.

Readying your AC unit for summer

Taking the steps to help your AC Unit function at their peak throughout the summer months can be done with our help.

Two of the steps that can be taken will be weatherstripping the windows and caulking air leaks – these will help keep the cool air inside the building.

Another step to do is turning back the thermostat from its original setting by seven to ten degrees for eight or so hours – this tactic can save up to 10% a year on heating and cooling costs.A fourth way of saving is through using a programmable thermostat.

A fourth way of saving is through using a programmable thermostat.

If you are hiring an air conditioning contractor, it may fair well to follow the below advice:

– Prior to doing anything, check the warranty on your current air conditioning unit to determine whether any repairs, replacements or tune-ups
– Arrange for annual maintenance on your AC Unit with a qualified technician. This will entail checking the airflow over the coil, testing for the correct fluid level, know as the refrigerant, reviewing the combustion process and ensuring proper airflow to each room
– Research the company you have hired, their work history and if there have been any complaints
– Similarly, check licensing by asking to see a copy of the contractor’s license and insurance before work stats
– Compare at least three estimates you have acquired before choosing a contractor

Buying an AC Unit

Air conditioning is becoming a common feature in offices and shops, leading to the increase of AC units sought after for homes.

What comes into question is which air conditioner should be bought. There are a number of factors that come into play with choosing the right AC Unit – there are essentially two main types of air conditioners available; single-unit models that are portable and will need to be vented through a window or door, and split-unit models that are permanently fixed to a wall.

Single-unit model

A single-unit or portable air conditioner, will often be easier to install, be a fairly cheap fix for cooling your home and allows the hot air to vent out through a hose, allowing it to be moved from room to room.
However, there are disadvantages that can become apparent such as venting the hose through an open window could potentially pose a security risk; portable air conditioners are not as effective at cooling compared to split-unit models – they will quickly get hot and leak heat back into the room; some models can be heavy, so ensure your chosen unit isn’t too heavy for you to lift comfortably and that the hand-holds are easy to grip.

Split-unit model

The advantages of acquiring a split-unit air conditioner come as follows: ideal for a room that often becomes too hot, a secure way of air conditioning your home – no need to leave windows open, quieter and more efficient that single-unit models, along with being more powerful than a single unit.
Among advantages come disadvantages such as the cost, it will be a larger amount than a single-unit model and a split-unit model will need to be mounted on an outside wall and may require a professional to install it.

Your AC unit

Central AC units are effective at cooling a home efficiently, providing that much-needed relief from that stuffy heat, come Spring/Summer time.

Although, your AC unit will only work well if the parts are kept clean and in a functional condition.
You will need to perform routine maintenance on your air conditioner so to keep the operating sufficiently.

Dirty filters will rob air flow and decrease the unit’s performance. Along with dirty filters, another energy waster is a dirty condenser coil.
If your AC unit is outside, it will likely collect the dirt the wind is blowing, thus the condenser coil becoming dirty which will not allow the sufficient airflow through the coil, therefore the refrigerant won’t be cooled as quickly, leading to a low efficiency.

Fan blades on the condenser fan or the squirrel cage fan inside that are damaged or unclean will eventually begin to vibrate and restrict the air flow.
Damaged or bent blades are what causes the vibration and will shorten the life of your motor. Build up of dirt and grime on the fan blades can also cause the vibration and restrict the air flow.

To see to these issues, your initial step would be to turn off the power to the AC unit and the outside condenser. You can then proceed to pick apart the condenser for a thorough clean.
To clean the coils, use a hose with a spray attachment and rinse.
When cleaning a blower fan, it is advised to call a professional to handle the job as they will be skilled in this area and have more expertise about the maintenance.

Things to know about air conditioning

During the warmer months, many homes will have air conditioning. However, air conditioning can be a necessity as well as a luxury.

What is air conditioning?

The first functional air conditioning was made in 1908, it made a promise to:

– Maintain a suitable humidity in all parts of a building
– Release the air from excessive humidity during certain seasons
– Supply a constant and appropriate supply of ventilation
– Remove micro-organisms from the air, along with dust, soot and other foreign bodies
– Cool a room depending on certain seasons
– Heat up rooms in winter

How it works

What an air conditioner does; moves the heat from your home to the outside, thus cooling the home.
They actually blow cool air into the home by pulling out the heat from that air, the air is actually cooled by blowing it over a cold set of pipes that are called evaporator coils.

This process is powered by a motor that runs in the compressor of your AC unit.

Maintaining the system

Filters should be changed in your air conditioning unit regularly so to keep the filter clean and the air that is blown out clean also, this may prevent any illnesses that could be caused by owing dirt and dust into the air which would then be breathed in.

To clean the system, a brush can be used on the obstructions and coils, however depending on the system, this may have to be done by a professional.

If your AC unit isn’t producing as much cold air as it would regularly, there may be a problem with the airflow or could indicate a refrigerant charge – this would need servicing.

Increasing your energy efficiency

One fo the biggest improvements for energy efficiency is sealing leaky ducts, as well as replacing dirty filters, cleaning the coils and maintaining the right charge and airflow.

Check if your outdoor condenser is blocked by any foliage or leaves that may be affecting its performance inside of your house.


The former points have focused mainly on cooling, whereas ventilation is probably one of the most important things an air conditioning unit can do.
Ventilation is needed to remove all of the contaminants that are generated indoors and may possibly lead to health conditions.
