📌 Federal Energy Tax Credit – QMID Numbers (Helpful Info)

If you installed a qualifying heat pump in 2025, you may be eligible for the federal energy-efficient tax credit (IRS §25C).

When filing, homeowners are often asked for a Qualified Manufacturer ID (QMID) — a 4-character code used on IRS Form 5695.

Below are commonly requested QMID numbers for major manufacturers.
(Shared for general reference — even if we didn’t install the system)

Heat Pump / HVAC Manufacturer QMIDs:
• Goodman / Daikin — I7Q6
• Bosch — K3M2
• Carrier / Heil — N8H2
• Lennox / Allied Air — L7S0
• Mitsubishi Electric — E8X7
• Trane / American Standard — B8T9
• Weil-McLain — 46H2

⚠️ Important:
Tax credits and eligibility can vary — always check with your tax preparer or accountant before filing.

If we installed your system and you need documentation (model numbers, AHRI certificates, invoices), just reach out — happy to help.

❄️ Extreme Cold Weather & Heat Pump Performance ❄️

With temperatures at or below 0°F, we’ve been getting a lot of questions about heat pumps and thermostats. Here are a few important things to know:

🔹 Thermostat vs. Room Temperature
In extreme cold, it’s common for a heat pump to maintain a temperature slightly below what the thermostat is set to. Heat pumps move heat rather than create it, and when outdoor temperatures drop this low, their capacity is reduced.

🔹 Nighttime Setbacks Can Cause Long Recovery Times
If you turn your thermostat down overnight, don’t be surprised if it takes many hours to recover in the morning — or never quite gets there. In very cold weather, heat pumps work best when maintaining a steady temperature.

👉 Best practice: Keep all thermostats set to the same temperature day and night during extreme cold.

🔹 Aux / Emergency Heat Is Normal
You may see auxiliary or backup heat running more often. This is normal when temperatures drop and helps the system keep up with demand.

🔹 What You Can Do to Help Your System
✔ Keep outdoor units clear of snow and ice
✔ Make sure supply and return vents are not blocked
✔ Close blinds at night to reduce heat loss
✔ Seal drafts around doors and windows
✔ Replace dirty air filters (this makes a big difference)

🔹 Reality Check on Heat Pumps
Heat pumps are very efficient, but no system is magic when it’s below zero. They’re designed to maintain comfort — not recover quickly from big temperature setbacks in extreme cold.

If your system is running continuously, that doesn’t mean it’s broken — it often means it’s doing exactly what it’s designed to do in these conditions.

📞 If you’re unsure whether your system is operating properly or have concerns about comfort, give us a call — we’re happy to help.

❄️Snowy Weather Heating Tip❄️

With all this snow and cold temps, please take a quick moment to check your heating systems, outdoor vents and exhaust pipe pipes.

Make sure they are clear of snow, ice and debris – blocked vents can cause your system to shut down or even trigger safety issues.

❄️A quick shovel out now can save you from:
🚨 No heat at the worst time.
🚨 Emergency Service Calls.
🚨Carbon monoxide risks

❄️ Cold snap alert!❄️

❄️With colder temperatures (and a possible storm approaching) heating systems tend to work overtime —and that’s often when small issues turn into big ones.

❄️ If you notice unusual noises, inconsistent heat, or no heat at all, please call us as early as possible.

❄️Early calls allow us to respond more efficiently and keep everyone on schedule. We’re here to help, please call 978-558-6526.
