Quick Note for Homeowners
Your home might have a smell.. It could be a small issue that you can fix easily. A simple cleaning of the condensate drain or evaporator coil can often solve the problem. These fixes do not cost a lot.
- It is an idea to get a detailed quote from a licensed HVAC professional. This will give you an estimate.
- If the smell is coming from the ductwork or hidden mold the costs might be higher.
- Make sure the estimate includes all equipment, labor, ductwork and electrical upgrades.
What Local Techs Check First
When local HVAC professionals evaluate your system they check some things. These things can affect how big the job is.
They look at:
- The condition of your ductwork
- Your electrical panel capacity
- The type of refrigerant used
- The drainage of your condensate line
- The cleanliness of your air filter
These problems can make a simple system swap more complicated. For example damaged ducts or a clogged drain line can cause standing water. This can lead to mold growth. Mold growth often causes smells that do not go away. The HVAC professionals will check these things to find the cause of the smell.
When replacement is smarter than repair
When it is better to get a system instead of fixing the old one it is usually because the repair costs a lot of money. If the repair costs than half of what a new system costs or if the system is really old like over 12 to 15 years old then it is probably better to get a new one. Also if the system keeps breaking down and needs to be fixed all the time then replacement is usually the way to go. New systems are better because they run cleaner and use kinds of refrigerants that are good, for the environment. They are also more efficient which means they use energy and that makes your monthly bills lower.. You will not have to make as many emergency calls for repairs.
Sometimes people ask me why their air conditioner still smells musty even after I fix it. This can be a reason to get a system especially if the smell is coming from mold that is hidden in the ducts.
