Knowing when it is the right time to have your HVAC system serviced can be hard. And if you wait too long to have someone come in and do a tune up, it can cost you a lot more in repairs than what you would have paid for servicing. It is much better to prevent problems than to try and repair them later. This is why it is best if you can detect problems early on. Here are some things you should be watching out for.
1. Loud Noises
Your HVAC system shouldn't be making loud noises at any time. It is normal to hear a gentle hum coming from the furnace or AC, especially if the unit is older. However, any noises shouldn't be noticeable when you are far away from the unit. If you can hear grinding, clanking, or any pounding from the unit, you need to turn it off right away and call for a repair man. It could just be a simple maintenance issue, but in some cases, loud clanking noises can mean a far bigger problem. The longer you ignore the problem, the worse it will get, and the more expensive the repair will be.
2. Water Pooling Around The Unit
If you have any water pooled around the AC or the furnace, this is a problem. It is very normal for the units to have mild condensation coming off the metal. You might even get a wet hand by touching the unit, but there shouldn't be so much that you get a pool of water at the base of the unit. Once again, if you notice this problem, make sure to power down the unit and wait until you can get an HVAC contractor there to look at the problem.
3. A Discolored Pilot Light
If your furnace has a pilot light, you should be checking the flame often to make sure that it is a healthy blue color. If the flame is anything other than blue, it could mean there is a gas problem. This is not only dangerous for your system, but it can be dangerous to everyone in the house. The furnace should only be run if the pilot light is healthy.
4. Poor Air Quality
If you feel like the air quality in your house has decreased, you should have you HVAC system looked at. Many times it is the ducts, filters, or the system in general that just needs a simple tune up.
By looking out for these things, you can detect problems early and keep your HVAC system in good shape.
