No AC Call: GE R22 unit manufactured in 1983. Found the condenser fan motor not operating. Tested the capacitor and found it had failed. Replaced the capacitor, but the condenser fan still did not operate. Tested the fan motor and confirmed the motor had failed.

Replaced the condenser fan capacitor and motor, then verified proper motor rotation and operation. While the unit was disassembled, inspected the condenser coil and found it heavily impacted with dirt and debris. Cleaned the condenser coil and reassembled the unit. System is now operating properly with discharge air temperature approximately 50°F.

🔧 A2L Refrigerant Safety Certified! 🔥

At Critical Heating & Hydronics LLC, safety isn’t something we take lightly.

We’re proud to be A2L Refrigerant Safety Certified, with training focused on the proper handling, installation, servicing, and safety requirements associated with today’s lower-GWP A2L refrigerants.

As the HVAC industry continues moving toward newer refrigerants such as R-32 and R-454B, proper training is more important than ever. A2L refrigerants are classified as mildly flammable, which means technicians need to understand the proper procedures, equipment, ventilation requirements, leak detection, and safety practices.

Our goal is simple: protect our customers, their families, their employees, and their property while providing professional HVAC service.

When you choose Critical Heating & Hydronics LLC, you can have confidence that we’re staying current with the changing HVAC industry and taking the safety of every installation seriously.

Trained. Certified. Safety First.

🔥 32 Years of Service — Time for a New Furnace! 🔥

Another furnace replacement completed by Critical Heating & Hydronics!

This 32-year-old American Standard 80,000 BTU, 80% furnace had provided decades of service, but it was time for retirement. We replaced it with a new Goodman 80,000 BTU, 80% AFUE furnace, maintaining the home’s existing heating capacity while providing a reliable new system for years to come.

But installing a furnace is only half the job — proper commissioning is just as important.

🛠️ Installation & Commissioning Included:
• Removed the 32-year-old furnace
• Installed new Goodman 80,000 BTU 80% furnace
• Adapted and connected the existing ductwork
• Verified gas piping and connections
• Checked and adjusted gas pressure
• Performed an external static pressure test to verify airflow and system resistance
• Performed a combustion analysis to verify proper combustion and safe operation
• Verified flue gas performance and combustion readings
• Tested heating operation and controls
• Completed final system startup and commissioning

The combustion analysis readings were looking very good, and the static pressure and gas pressure checks gave us the information needed to verify the new furnace was operating properly with the existing system.

A furnace replacement isn’t just about putting a new box in place. Proper testing, setup, and commissioning are what make sure that new equipment operates safely, efficiently, and as designed.

After 32 years, this American Standard has officially earned its retirement. 🔥

A little HVAC misinformation we came across this week…

Not gonna name any HVAC companies, but a customer contacted us after being told this was “crystallized carbon monoxide” and that their 80% furnace was being phased out.

Neither is accurate.

Carbon monoxide (CO) is a gas. It doesn’t crystallize or leave behind a powdery residue on a furnace.

What you’re seeing is much more consistent with oxidation/corrosion from the galvanized metal around the flue and draft hood, mixed with accumulated dust. Heat and moisture from years of combustion can cause this type of buildup.

And as far as 80% furnaces go, they’re still a legitimate option for replacement in many existing-home applications. Don’t let someone tell you that you have to replace an existing 80% furnace with a 96% furnace simply because it’s “being phased out.”

HVAC should be diagnosed with facts—not made-up terminology.
