What Causes Poor Airflow in Alberta Homes During Summer?

As temperatures rise in Alberta in the summer, homeowners want their air conditioning units to maintain comfort in their homes. Yet one of the more popular HVAC issues is the lack of air circulation, which may cause cooling efficiency to go down and cause energy expenses to rise. When it comes to home maintenance, and HVAC research, I have seen that many people don’t pay attention to the airflow problem until they start noticing their home isn’t as comfortable as they think it should be. Familiarizing yourself with the underlying causes can help homeowners take preventative measures and be aware of when to reach out to a professional, like Hydro-Flo AC repair services, for help.

Dirty Air Filters Restrict Airflow: This is the reason for Hydro-Flo AC Repair!

During Alberta summer months, poor air circulation is often caused by a clogged air filter. The purpose of an air filter is to trap dust, pollen, pet dander and other airborne contaminants. These pollutants build-up over time and prevent air from being able to flow through the HVAC system.

The air conditioner will run with greater frequency and on higher levels to compensate for a dirty filter, which means that it will be less efficient and will wear out parts more quickly. It is possible to dramatically improve air flow in many homes by changing the filter once a month or as needed every three months. If homeowners observe reduced airflow from the ventilation at their home, it is advisable to get in touch with Hydro-Flo AC repair specialists to check and maintain the cooling systems in the home so that they do not cause more damage.

Hydro-Flo AC Repair: Blocked or Leaking Ductwork

Air ducts are very important in providing cool air to the house. Leaky, broken or blocked ductwork can lead to significant air loss. Attic, crawl spaces or wall cavities can leak conditioned air from the living space before it reaches the living areas, due to small leaks.

There have been a lot of times I’ve had homeowners believe that their air conditioner was beginning to fail when it was actually a duct leakage problem. Duct inspections can be done by professionals, and they can find any hidden issues and get the air flowing again. Avoiding the hassle of Hydro-Flo AC repair services and executing regular maintenance can help ensure the entire cooling system runs smoothly during the summer season.

Closed or Obstructed Air Vents 

Furniture, rugs, curtains, and household items can inadvertently block air vents. If the supply or return vents are blocked, the flow of air is limited and uneven cooling can occur in rooms.

Many Alberta homeowners pay close attention to the setting on the thermostat without considering that ventilation is a major factor in airflow and relies on open vents. Keeping all vents open and clear ensures that conditioned air flows properly and that temperatures are kept constant within the interior during extreme hot weather.

Frozen Evaporator Coils Reduce Cooling Performance 

Poor airflow can also be caused by a frozen evaporator coil. The coils may freeze when they are not getting enough air movement, if the refrigerant temperature is too low or even if the parts are dirty. When ice is formed the system begins to have trouble moving air through the unit properly.

Common symptoms are: decreased airflow, warm air from vents, and increased cooling time. It is important to attend to it as soon as possible, to prevent overloading the compressor. When HVAC experts can check the cause of the problem and get the system working properly before the damage is done, it is a lot easier.

Undersized or Aging HVAC Systems 

Older homes in Alberta are still using old AC units that were installed many years ago. Older equipment blower motors deteriorate, parts break down and air leakage decreases.

Sometimes the HVAC system may be smaller than what is needed for today’s household requirements. The cooling needs may exceed the capabilities of the system due to the addition of rooms and/or changes to the occupancy. When upgrading old equipment, it is often beneficial to improve the air flow, increase energy efficiency and create more consistent indoor environment during hot weather.

Dirty Condenser Units Affect Air Movement 

For outdoor condenser units, they must be vented properly in order to draw out heat. The surrounding can be filled with dirt, grass clippings, leaves and debris which can restrict heat transfer and lower cooling efficiency.

Proper condenser maintenance and clearance facilitates efficient operation. Outdoor units have to work hard to maintain the desired temperature during Alberta’s summer months and regular maintenance is especially important to ensure proper air flow.

Thermostat and Blower Motor Problems 

Poor airflow may not be due to physical blockages, but mechanical or electrical problems. When thermostats are not working properly, they can cause false signals to be sent to the heating and cooling system, and when blower motors fail, they can be unable to push air through the ductwork.

These issues may be progressive and not be recognized until there is significant loss of cooling performance. Problems can be small and will cost a lot of money if not detected by a professional diagnostic.

Conclusion

Summer poor ventilation in homes in Alberta can be caused by dirty filters, duct leaks, duct blockage, frozen coils, old equipment, dirty condenser units, and blower motor issues. Prompt action on these issues creates a more comfortable indoor environment, reduces energy costs and increases the life of HVAC systems. Through my own experience and industry research, the best way to avoid any airflow issues is to keep the equipment maintained on a regular basis. Once cooling efficiency starts to drop, hiring a professional Hydro-Flo AC repair service is a great way to pinpoint the problem and resume proper air circulation in the house.
