HVAC Problems & Its Solutions
1. Refrigerant Leaks
2. Humidity
3. Electrical Issues
4. Poor Air Flow
5. High Energy Bills
Refrigerant Leaks
If you notice that warm air is blowing when 
the AC is supposed to be on, the cause might 
be a refrigerant leak. The coils and refrigerant 
lines in your AC unit develop tiny leaks over 
time and they become very obvious during 
the summer.
Humidity
Summer days are often humid days. While high 
humidity is a nuisance outside, it can be 
downright problematic inside. Not only is it 
uncomfortable, but high humidity indoors can 
stretch wood frames causing damage. It can 
also lower indoor air quality. As a result, we 
recommend keeping humidity levels indoors 
between 30-50%.
Electrical Issues
There are components in your HVAC system 
that are more vulnerable to damage. The 
capacitor, for example, can get overheated due 
to the outdoor temperature or due to overuse. 
Yard work and renovations can also cause 
unintended damage to AC units. These can 
result in electrical issues that can cause 
breakdowns.
Poor Air Flow
If you’re noticing that air flow is worse, then 
many things could be to blame. It could be an 
issue with your air filter. Or, it could be due to 
grass growing on the outside of your AC unit. 
Keeping the grass trimmed and the air filter 
clean can help prevent air flow problems during 
the times when good air flow is needed the 
most.
High Energy Bills
Although it’s common to expect high energy bills 
during the summer, sometimes energy bills are 
much higher than expected… and it may not be 
due to rates changing. HVAC systems (especially 
air conditioners) can get less energy efficient 
over time, and this is especially pronounced 
during times when we rely on it the most. Getting 
proper HVAC maintenance in the spring can help 
prevent these issues from cropping up.
