A dirty air filter doesn’t just affect airflow — it affects system performance, efficiency, and static pressure too.

These pictures show the difference between a one-year-old dirty filter and a brand new filter using a Testo manometer:

🔹 Dirty filter: 0.14 in. w.c.
🔹 New filter: 0.10 in. w.c.

At first glance, that may not seem like a big difference, but the dirty filter caused roughly a 40% increase in filter pressure drop. That extra restriction forces the system to work harder to move the same amount of air.

Another thing many homeowners don’t realize: properly taping filters in place can help reduce air bypass around the edges. When air slips around the filter instead of through it, dust and debris can still end up inside the system and ductwork.
A clean, properly sealed filter helps: ✅ Improve airflow

✅ Reduce dust buildup
✅ Protect the equipment
✅ Improve indoor air quality
✅ Keep the system operating more efficiently

Rainy, mild temperature days can make your home feel sticky and uncomfortable — even when the AC is running. 🌧️🏠

That’s because AC units don’t always run long enough during mild weather to remove excess humidity from the air, especially when oversized.

High indoor humidity can lead to:

- Musty odors
- Condensation on vents/windows
- Poor comfort
- Mold and mildew concerns

At Avalanche Heating and Air Conditioning, we can help improve your indoor comfort with solutions like:

✅ Whole-home dehumidifiers
✅ Electric heat reheat kits for heat pump systems
✅ Load Calculations to ensure that your HVAC system is properly sized

If your house feels damp during rainy weather, give us a call and let’s get your comfort back under control. 💨

HVAC Capacitorn Replacement

Changing a capacitor on an AC Unit in Statesville, NC and thought I'd give my best explanation on the process.

Dirty air filters will send your HVAC system into a downward spiral of poor performance, leading to a service call if not caught in time. A dirty air filter causes low total system air flow, which causes the following problems:

- Rapid freezing of the AC system
- Drain issues due to excessive moisture and ice buildup. This can cause your Air Handler to flood with water and ruin the cabinet insulation, and can damage electrical components.
- Worst case, it can damage your compressor under some circumstances.

Want to learn what circumstances can cause compressor damage while others may not? At 50 likes, I'll make a post explaining.

Here are some contact points that have been removed from a compressor contactor (the one in my hand and the one on the left is a new point).

Outside of a capacitor, this is probably the second most failing part of an HVAC system. When they reach this point, it creates a poor connection, which generates unwanted heat that eventually causes the part to fail.

Another Unit checked, cleaned, and waxed!

Away until the week of the 20th. I will have my phone on me if anyone needs to speak with me but may have limited service. While gone, if any HVAC services are needed, I recommend Duncan Heating and Air Conditioning or Aither Heating and Air Conditioning. Thank you all for the support!
