What size HVAC system do I need for my home?
That varies with the size of your home and living situation. There is no rule of thumb for an HVAC system so it is best to have a trained professional assess your home to provide an accurate review and recommendation.
How can I increase the efficiency and lifetime of my HVAC system?
Each system is different, but the best way to get the most out of your HVAC unit is to change your air filters. Regularly changing your air filters allows your unit to work more efficiently to provide you with clean, filtered air.
How often should I replace my air filter?
Changing the air filter on your HVAC unit differs case by case. You should check the air filter monthly to ensure there is no substantial build-up. Changing the air filter can help improve the efficiency of your HVAC system between 5% and 15% while also ensuring your unit is operating at peak performance.
Some factors that can affect how often you should change your air filter are:
- How many people are in your home – more people equals more dust and dirt in the air \
- If you have pets – it helps to reduce dander
- If you are in a high construction area (such as a new subdivision) or an area with lots of pollen (trees and plants)
What is the ideal temperature to keep my thermostat set at?
Ideally, you want to set your thermostat lower in the winter and higher in the summer. Doing this reduces the difference between the temperature outside and the temperature inside, thus minimizing the need for your HVAC unit to work harder at heating/cooling your home. This not only increases the efficiency of your unit but also helps save money on your bill.
If you’re away for a weekend or longer, you should not shut your system off completely but rather make use of the hold/vacation feature, if there is one. Otherwise, set your thermostat to a few degrees higher than normal (in the summer) or lower (in the winter).
If you were to turn your unit off completely, it could result in higher humidity levels inside the home, which has the potential to lead to mould growth due to decreased circulation.
Is there anything I can do at home if I think my unit is malfunctioning?
Your HVAC system is complicated, and it is best to have a certified professional identify the issue; however, there are a few basic steps you can try which may correct the problem.
- Make sure your circuit breakers are in the ON position
- Open the supply and return vents and make sure they’re unobstructed
- Check the settings on your thermostat
If after completing these steps your system is still having issues, do not hesitate to call an Afterglow professional.
