Getting Your AC Ready for Spring and Summer

Spring is here and summer is just around the corner. Instead of waiting until the heat comes, get your air conditioning unit ready now. During the start of the summer months, we get a lot of calls for fixing air conditioning units, it’s best to inspect yours ahead of time.


Change the filter

Most people don’t change the filters in their air conditioners often enough. Before you start to use your unit, check to make sure the filter doesn’t need cleaned or replaced. You should be replacing the filter on your air conditioner once a month when it is in use. Some air conditioners have a permanent, reusable filter. If yours has a permanent filter, clean it once a month with a water and vinegar solution.

Clean the lines in your AC unit

The condensation lines in your air conditioning unit can become plugged up with debris. You really don’t want this to happen as this can cause a big mess. It can also be expensive to repair. A lot of times these lines become backed up due to algae growth. If it is not draining properly, you can use an algaecide to kill the algae growth.

Remove debris from around the unit

After a long season, a lot of things can grow around or even in the air conditioning unit. Look for tall grass, weeds, or vines that may be obstructing it. Be sure and remove any plants or other items that are blocking it and making your air conditioning less effective.

Clean the coils and fins on the outside of your AC unit

After sitting unused for a long period of time, your AC unit can collect a lot of dust and it is exposed to the elements, especially if you don’t use a cover. Disconnect the power and wash down the outside of your AC unit. If it is extra dirty, you can buy a specialized cleaner for your unit. To clean the fins, gently clean with a soft brush. Also try and straighten out any severely bent fins.

10 Most Common HVAC Problems

This symbol indicates a possible danger — if this is located next to the issue you’re experiencing, contact a professional HVAC technician immediately!

1) Lack of Maintenance

Just like any good technician will tell you, regularly scheduled maintenance by a professional is a must to keeping your high-end purchases in tip-top shape. Many common HVAC problems can be avoided with proper maintenance by a certified service contractor. Neglecting to perform regular maintenance on your HVAC system will most likely result in costly repairs down the road and a possibly poor-functioning system.

Regular maintenance on your HVAC system also means getting your ducts cleaned. Sam’s Heating & Air Conditioning offers this service. Contact us for more information or to schedule an appointment. Professionally having your ducts cleaned out is also a great idea if you just renovated your home, had animals living in your system, recently encountered mold or other contaminants within your system, or if someone in your home is suffering from an unexplained allergy-related illness.

2) Dirty/Clogged Filters

With time, HVAC unit filters get dirty and clogged. Filters should be changed regularly to prevent this from happening. When a clogged filter isn’t changed, the airflow is reduced causing the system to work overtime — this can lead to an increase in your energy bill. A dirty filter can also cause more allergens to circulate through the HVAC system. Holding a filter up to the light is a good indicator of whether it needs to be replaced or not. If no light passes through, it’s time to change the filter.

3) Pilot or Ignition Problems

Ignition problems can be due to a number of causes. A dirty pilot, flame sensor, or burner can cause a pilot outage, short cycling, furnace lockout, or delayed ignition of the burners. It could also be the result of a gas supply problem or wear and tear. Whatever the reasoning, this issue needs to be addressed by a professional since this deals with dangerous elements like natural gas and high voltage.

4) Thermostat Malfunctions

It’s easy to blame something within the HVAC system when things go awry, but occasionally the problem is within the thermostat itself. The good news is that sometimes the problem isn’t a problem at all, but just a minor issue with how the thermostat is set. Your thermostat regulates the timing and amount of hot or cold air your unit should produce. Referring to your owners manual may prevent you from paying for a costly or unnecessary service call. If your thermostat runs on batteries, be sure to check those as well.

5) Unusual Furnace Noises

Noise from your furnace can be part of normal operation, however, some sounds may be a warning or indication of a mechanical problem.

  • A high-pitched screeching noise can be a motor bearing problem. Another screeching sound could be a bad belt.
  • A sound that is similar to a card stuck inside the spokes of a bicycle typically indicates something is stuck in the blades of the blower or something is stuck inside the housing of the furnace.
  • In the unfortunate event that you hear a scraping sound like metal parts rubbing together, you’ll need to call a professional right away as this can be the result of a much larger issue such as a broken wheel or the blower assembly hitting the housing.

6) Blown Fuses or Tripped Breakers

A common reason the furnace trips a circuit breaker is that the blower is overworking. If something is blocking airflow to your system, your blower has to overcompensate. That being said, one of the main reasons is a dirty air filter. Check your filter and replace it if needed before resetting your circuit breaker.

7) Dirty Condenser or Evaporator Coils

Chances are regular maintenance isn’t being conducted if your HVAC unit has this issue. You can hose off the outdoor coil after shutting off the power to the condenser. The indoor evaporator coil will need to be cleaned by a professional if it is extremely dirty. If regular maintenance is performed on your HVAC unit, coils should remain relatively clean and could possibly only need a professional cleaning roughly every three years.

8) Drips and Leaks

While both air conditioners and high-efficiency furnaces can produce condensation, drips and leaks are traditionally signs of a bigger problem. The common causes of leaks are:

  • Gas Line Leaks – usually imply a broken or cracked furnace heat exchanger
  • Refrigerant Leaks – Mainly caused by weak joints or faulty connections in an AC or heat pump
  • Water around the air conditioner – typically caused by a clogged drain hose or dirty coil

9) Blower Runs Continuously

There are several reasons a furnace blower may run continuously. First, check to see if the fan switch on the thermostat is on – this will cause the motor to run continuously. If that didn’t do the trick, then you most likely have one of these three problems:

  1. Your furnace fan limit switch is set to “manual override”
  2. The fan limit switch is faulty and needs to be replaced
  3. There’s a problem in your thermostat wiring

Unfortunately, you’ll need a professional to fix those last two problems.

10) Outdated HVAC Design

Most heating and cooling equipment have a service life of around 20 years. However, unmaintained units face reduced efficiency and lifespans. Older units may need to be completely replaced, especially if home or office renovations have taken place since the original installation.

Another good reason to consult an HVAC expert: you may find that simple ductwork changes can make a huge difference in your HVAC airflow and comfort.

If your furnace is more than 10 years old, a new high-efficiency model may provide better comfort and cost far less to operate.
