Reliable Heating & Cooling With a Boiler Upgrade in Albuquerque

Our customer’s home in Northeast Albuquerque was experiencing ongoing issues with an outdated boiler and an older cooling setup that could no longer keep up. Our team replaced the failing boiler and completed a partial system upgrade to support the existing evaporative cooler and mini split units. With a new high-efficiency heating boiler installed and system improvements completed, the home now operates more reliably and efficiently year-round.

Job Overview

• Location: Albuquerque, NM
• Client Type: Residential homeowner
• Scope: Partial HVAC system replacement including a boiler upgrade
• Equipment Installed: Navien NFB Series 95% High-Efficiency Condensing Heating Boiler
• Additional Work: System reconnections, testing, and integration with existing cooling equipment
• Why It Mattered: The older boiler was failing and unable to provide consistent heating, putting comfort and reliability at risk

What We Found

During our diagnostic review, we found that the existing boiler had reached the end of its service life. It struggled to deliver steady heat, and several components showed clear signs of wear. Our customer’s existing cooling system included a package unit, evaporative cooler, and three cooling-only mini split systems, all installed at different times. The heating boiler and a 64.5-gallon indirect water heater had been installed 11 months prior but required replacement due to performance concerns and system failure.

The Solution

We removed the failing boiler and prepared the mechanical area for the new installation. Our team installed a Navien NFB Series 95% high-efficiency condensing heating boiler, ensuring proper venting, gas connections, and hydronic plumbing. We reconnected the system to the existing indirect water heater and cooling equipment, then verified all control wiring and safety features. Once installation was complete, we pressurized the system, bled air from the lines, and performed a full startup test to confirm strong heating output and stable operation. Final checks included sensor verification, temperature consistency, and efficiency tuning.
