As a bunch of us are dealing with heat waves and it’s only June, I have some tips for you to apply to your home cooling.
- Change out your HVAC filter to a lower MERV filter now. The high merv allergen filters reduce air flow and to be honest, you really need the hvac system to push as much air flow to keep the house cool.
- Clean out the furnace condensate trap / safety float if you haven’t done it already. The condenser cools down the air, which takes out moisture and also dust. The dust settles in the trap but if it clogs the trap it turns the switch off and furnace turns off. This is a common hvac problem. Clean it out- there are lots of instructions online.
- If your upper levels are way too hot and your basement way too cool- get a booster fan for your register vents upstairs. 💨 it boosts the air flow up towards the upper levels keeping them much cooler than they would be otherwise. If you need a link- I will try to find one and post in the comments.
- If you have ceiling fans, make sure they are on and turning so that the air from the flow wants to move down from the ceiling. Keep them on all the time.
- If you haven’t had AC check up in a few years, it is good practice to get it done. When doing so, go outside and ask to take a picture of the capacitor. These things break and are an easy fix- so it’s good to have one around (Edit to add- so that if it does break the HVAC guy can just install it that day when it does break.) The maintenance plan will also clean your coils and do other things so you can learn more about your hvac and save the hassle of being in a sweltering house.
