Problems with your HVAC system always seem to happen at the worst time in the dead of winter when you need heat the most. That’s why it’s essential to be aware of the most common wintertime HVAC problems, so you can have them fixed before they cause a complete breakdown.
Here’s a list of the most common winter HVAC problems, along with some tips on how to prevent them:
1. Frozen evaporator coils
One of the most common winter HVAC problems is frozen evaporator coils. This can happen when the air filter is dirty and blocks airflow, causing the coils to freeze.
To prevent this problem, change your air filter regularly and clear the airflow around your evaporator coils.
2. Clogged air filter
Another common wintertime HVAC problem is a clogged air filter. A dirty air filter can restrict airflow and cause the evaporator coils to freeze. What happens next is that the ice buildup can cause water damage to your home.
The best way to prevent a clogged air filter is to change it regularly. Depending on your filter type, you should change it every one to three months.
3. Malfunctioning thermostat
You’ll notice this problem right away-the temperature in your home isn’t what you set it at on the thermostat. If your thermostat is malfunctioning, it can cause your heating system to run more than it should, leading to higher energy bills.
You can’t prevent a thermostat from malfunctioning, but you can have it serviced regularly to ensure it’s in good working condition. At least once a year, have an HVAC professional come out and clean and calibrate your thermostat.
4. Leaky ductwork
Ductwork not properly sealed can leak heat, leading to wasted energy and higher heating bills. In addition, leaks in the ductwork can pull in dirty air from the crawlspace or attic, which can circulate throughout your home.
If you suspect there are leaks in your ductwork, have an HVAC professional come out and take a look. They can seal the leaks with mastic or metal tape.
5. Old or failing heating system
An old or failing heating system is the most common reason for HVAC problems in the winter. If your system is over 15 years old, it’s probably time to upgrade.
A new heating system will be more efficient and provide better home heating. In addition, a new system will come with a warranty, so you’ll have peace of mind knowing that it’s covered in case of any problems.
The problem is many people can’t afford to replace their entire heating system all at once. If that’s the case, you can have it done in phases, starting with the most critical parts first.
For example, you might replace the furnace first and then the air conditioner a few years later. Or, you could replace the outdoor and indoor units first.
Whatever you do, don’t wait until your heating system breaks down completely before you replace it. That’s when you’ll be stuck in the coldest weather with no heat!
If you’re having problems with your HVAC system this winter, don’t wait to have them fixed. Instead, contact an HVAC professional immediately to resolve the problem before it causes a complete breakdown.
And be sure to keep these tips in mind to prevent wintertime HVAC problems in the future. You can keep your heating system running smoothly all winter long by taking some preventative measures.
