ERV's are a great way to get fresh air into your house, and stale air out.

They work great when integrated with a ducted heat pump system.

They help with indoor air quality and efficiency.

This is a "Renewaire" ERV that we installed in 2025 on a Mitsubishi 12,000 BTU air handler. The system works great!

New service alert 🚨 : Attic Fans Matter More Than You Think

Most people don’t think about their attic… until something goes wrong.
But what happens up there can have a big impact on your comfort, energy bills, and even the life of your heating system.

That’s where attic fans come in.

Attic fans help:

Remove excess heat in the summer

Reduce moisture buildup in the winter

Prevent mold and wood rot

Take strain off your heating and cooling systems

Improve overall energy efficiency

When an attic gets too hot or too damp, your heating system has to work harder to keep your home comfortable. Over time, that extra strain can lead to higher bills and unnecessary wear on your equipment.

We’ve seen homes where poor attic ventilation caused:

Ice dams

Condensation issues

Shortened system life

Uneven temperatures throughout the house

A properly ventilated attic helps your heating system do its job the way it’s supposed to.

If you’re not sure whether your attic ventilation is working correctly, we can take a look during your next service visit.

A lot of homeowners don’t realize how important their attic is to the performance of their heating system.

If your attic is too hot in the summer or full of moisture in the winter, your system has to work a lot harder to keep the house comfortable.

That’s where attic fans come in. They help remove heat and moisture, protect your roof structure, and reduce strain on your heating equipment.

We’ve seen issues like ice dams, condensation, and higher energy bills just because of poor attic ventilation.

If you’re not sure what’s going on in your attic, we can take a look during your next service visit. Just send us a message or give us a call.

“Mini splits? Don’t those cost like $17,000?”

We hear that all the time.

And yes… they can.
But the truth is, every home is different, and many mini split installs cost much less than people expect.

We’ve installed systems for:

-Single rooms
-Small homes
-Additions and garages
-Full-house heating and cooling

Sometimes it’s a simple, affordable solution. Other times it’s a larger, whole-home system. The only way to know is to take a look at your space and talk through your goals.

What we’ve found is that a lot of people who thought mini splits were out of reach were pleasantly surprised once they saw real numbers.

If you’ve been curious about:

-Lower heating bills
-Better summer cooling
-Getting rid of old electric baseboard or oil
-A system that’s quiet and efficient

Send us a message and we’ll walk you through your options.
No pressure, just honest advice.

This past summer we helped a homeowner who had a camp that was unbearably hot—and because of the setup, window AC units weren’t an option.

Our solution:
A simple 1-to-1 wall-mounted heat pump system, 24,000 BTU, designed to cool the space efficiently and quietly without taking up window space.

The result?
❄️ Cool, comfortable air all summer long—and a happy homeowner who can finally enjoy their camp again.

Sometimes the simplest systems make the biggest difference.

📞 Have a space that’s too hot and short on options?
Only Heat Pumps can help find the right solution.

🔧 Why Routine Equipment Checks Matter

During a recent service visit, we discovered a small animal inside an outdoor heat pump unit. Unfortunately, it caused an electrical short that damaged the system’s control board, resulting in a complete system failure.

While this isn’t something homeowners expect, it’s a real risk—especially in outdoor equipment exposed to the elements and wildlife.

This is exactly why thorough inspections during service visits are critical:
✔ Catch hidden issues before they cause major damage
✔ Prevent unexpected system shutdowns
✔ Protect expensive electrical components
✔ Improve long-term system reliability

Problems like this often go unnoticed until the system stops working entirely.

🔍 Routine service isn’t just maintenance—it’s prevention.

If your heat pump hasn’t been checked recently, now’s the time.
