One of the easiest ways to protect your HVAC system? Change your air filter.

It’s a simple task that makes a big difference.

A clean filter helps:

✔ Improve airflow
✔ Increase energy efficiency
✔ Reduce strain on your equipment
✔ Improve indoor air quality
✔ Help prevent costly repairs

During the summer months, we recommend checking your filter every 30–60 days depending on your home, pets, and usage.

A simple thing can help protect one of the biggest investments in your home.

Need help finding the correct filter size? Give us a call—we’re happy to help.

As we move toward May, demand starts to shift.

More service calls.
More breakdowns.
Fewer open install dates.

Homeowners who wait until summer often face:

• Limited scheduling
• Higher urgency decisions
• Days without cooling

Right now, you still have control.

That window doesn’t stay open long.

Secure your install before peak season begins.

Not when it fails.
Not when you’re uncomfortable.

It’s not finished… until it’s sealed.

Every system we install ends the same way
with our custom Schoonmaker sticker placed on the unit.

Not just for branding but for peace of mind.

So years from now, when service is needed or questions come up, homeowners know exactly who to call.

Because we don’t just install systems…
we stand behind them.

From startup to final walkthrough, every detail matters.

That’s the Schoonmaker standard.

Most HVAC systems don’t just stop working they decline.

Lower efficiency.
Longer run times.
Higher energy bills.

By the time summer arrives, your system is already under stress.

Replacing or servicing your system now means:

• Better scheduling
• Smarter investment decisions
• A home that’s ready not reacting

The difference is planning ahead.

Not all HVAC systems are built the same.

And not every system meets our standard.

That’s why we trust Gree Comfort

This inverter-driven system delivers:

• Higher efficiency with lower energy consumption
• Quieter operation no loud cycling
• Consistent, balanced comfort throughout the home
• Advanced technology built for long-term performance

For homeowners, that means:
Less noise. Lower bills. Better comfort.

For us, it means installing a system we stand behind.

At Schoonmaker Heating & Air, every product we install is selected with intention because your comfort isn’t something we compromise on.

The best HVAC decisions are never made in the heat of summer.

They’re made now when you have time to plan, design, and install the right system without pressure.

At Schoonmaker Heating & Air, we approach every home with intention:

• Proper system sizing
• Clean, efficient installs
• Long-term performance in mind

Because comfort should feel effortless not reactive.

April is where that starts.

Where comfort starts long before the walls go up.

New construction HVAC isn’t just installation it’s planning, precision, and performance from day one.

At Schoonmaker Heating & Air, we work alongside builders and homeowners to design systems that deliver:

• Proper load calculations (no guessing)
• Custom duct design for balanced airflow
• Clean, efficient installs that integrate seamlessly
• Long-term energy performance built into the home

Because in custom homes, comfort isn’t optional it’s expected.

This project is another example of doing it right from the ground up.

If you’re building or planning a custom home, now is the time to bring HVAC into the conversation early.

What’s happening above your ceiling matters more than you think.

Inside the attic is where your HVAC system actually delivers comfort to every room in the home. The ductwork you see here is responsible for distributing conditioned air throughout the house.

When duct systems are designed and installed correctly, homeowners benefit from:

✔ Balanced airflow in every room
✔ Consistent temperatures throughout the home
✔ Improved energy efficiency
✔ Quieter system operation

However, poorly designed ductwork can lead to:

• Hot and cold spots
• Higher energy bills
• Reduced system performance
• Increased wear on equipment

That’s why proper HVAC design includes load calculations, duct sizing, airflow planning, and strategic vent placement before the system is ever installed.

At Schoonmaker Heating & Air Conditioning, we take the time to design HVAC systems that perform efficiently and keep homes comfortable year-round.

Because true comfort starts behind the ceiling.
