Date Published: June 24, 2022

If you find yourself constantly Googling questions regarding your air conditioning system, you have come to the right place! We don’t expect you to be the air conditioning expert, so having simple or detailed questions is normal. In this blog, we will answer common homeowner questions about everything HVAC!

How can I tell if my air conditioner is broken?

If your air conditioner is broken, there are likely warning signs such as:

  • Warm air flowing from your vents
  • Insufficient airflow
  • High utility bills
  • Strange noises

When should I replace my air conditioner?

With proper upkeep and preventative maintenance, your unit can last around 15 years. Frequent breakdowns and costly repairs can start around the 10th year. Homeowners start replacing their systems depending on the price to continue repairing.

Which way do I put in my air filter?

Air filters have arrows printed on the sides to indicate which way to install. If your filter is on the wall, the arrows should face the wall. If on the ceiling, the arrows should face the ceiling. If you are replacing your furnace air filter, the arrows should face the furnace. Take note of the previous air filter’s placement and replicate it if placed correctly.

Why is my air conditioner freezing up?

The most common reason why your air conditioner is frozen is due to a dirty or clogged air filter. A dirty filter restricts airflow, causing the coils to freeze. The coils need warm air to blow across them, which is restricted with a dirty air filter.

Why is my air conditioner not blowing cold air?

There could be multiple reasons causing your air conditioner to blow warm air, but here are the most common:

  • Leaking or Low Refrigerant
  • Dirty Air Filter
  • Thermostat Issues
  • Problem with evaporator coil
  • Blocked Condenser

How often do I need to change my air filter?

You should be changing your air filter at least every 90 days. Depending on factors such as indoor pets, air filters should be changed about every two months.

What are the different types of air conditioners?

There are many cooling options for your home, but the most common air conditioners are:

  • Central Air Conditioner: circulate cool air through a system of supply and return ducts
  • Window Air Conditioner: a single unit with all of the parts and components contained inside one box or casing
  • Portable Air Conditioner: a cooling system that can be moved around easily, just requiring a window and electrical socket
  • Ductless Mini Split: one indoor and one outdoor unit which do not require ductwork

  • Inadequate maintenance
  • Drainage problems
  • Sensor problems

Why is my air conditioner making noises?

It is normal for your air conditioner to make a little noise, but if the unit begins banging, squealing, or rattling something could be very wrong. Noises can indicate a broken or loose part, which can develop into a much bigger problem.
