🚨 Tech Tip — Change Those Air Filters! 🚨

Yes, that’s ICE in both pictures — and gallons of water sitting inside the return plenum! 😳

The cause? A severely clogged air filter restricted airflow across the evaporator coil, eventually causing the coil to completely freeze over.

A simple air filter can make a BIG difference. Restricted airflow can lead to poor cooling, frozen coils, excessive water and even costly system damage.

Don’t let a $10–$20 filter turn into a much more expensive HVAC repair!

🔧 Check your filters regularly and keep your system breathing properly.

💧🚨 Prevent Water Damage Before It Starts! 🚨💧

This homeowner experienced ceiling damage after their HVAC condensate drain backed up and overflowed. This is not the first time this particular customer has experienced this same issue.

To help prevent it from happening again, NFS Heating & A/C Services installed two electronic condensate overflow safety switches. If the drain begins to back up, these safeties automatically shut the system down before costly water damage can occur.

If your air handler is installed in an attic or above a finished ceiling, these inexpensive safety devices can provide valuable peace of mind. This is also a code requirement in Maryland.

🔧❄️ From Maintenance Visit to New System Installation ❄️🔧

This customer in Waldorf, MD originally scheduled a routine HVAC maintenance visit. During our inspection, we found that their aging system had multiple issues that made continued repairs difficult to justify.

After discussing the available options, the homeowner decided that replacing the system was the best long-term investment.

We installed a new high-efficiency heat pump system, providing improved comfort, increased reliability, and greater energy efficiency for years to come.

Preventative maintenance isn’t just about cleaning equipment—it’s about understanding the overall condition of your HVAC system so you can make informed decisions before an unexpected breakdown occurs.

If it’s been a while since your last HVAC inspection, now is a great time to schedule one.

🔧HVAC Tech Tip🔧

Clogged condenser coils and dirty air filters are costing homeowners an exceptional amount of money every summer.

Ladies & Gentlemen — clogged condenser coils cause a wide range of A/C system problems, including:

❌ Overworked compressors
❌ Reduced system efficiency
❌ Overheated condenser fan motors
❌ Capacitor failures
❌ Higher electric bills

The job of your outdoor condenser is to reject heat from the home. When the coil becomes clogged with dirt and debris, it can no longer release heat properly — causing the system to work harder and run hotter.

Dirty air filters create another major issue: restricted airflow.

Reduced airflow can lead to:
❌ Poor cooling performance
❌ Frozen evaporator coils
❌ Long run times

Changing your air filter regularly and keeping your condenser coil clean can help prevent many costly HVAC breakdowns.

NFS Heating & A/C Services is here to help keep your system running properly this summer.

🌤️ Good morning Facebook & Happy Thursday

This evaporator coil was found completely clogged, due to the previous air filters being the incorrect size. Over time, the filter would fall out of the filter rack, allowing dirt and debris to bypass the filter and build up directly on the coil.

This eventually led to:
❌ Cooling issues
❌ Heating issues
❌ Restricted airflow
❌ Higher energy usage
❌ Costly cleaning and repairs

Situations like this are exactly why proper filter sizing and routine HVAC maintenance are so important.

Don’t wait until your system stops performing properly or breaks down completely.
