When Albuquerque’s summer heat and cool desert nights put your HVAC system to the test, an aging system can quickly show its limits. Uneven temperatures, frequent cycling, or higher energy bills are often signs it’s time for a replacement. Recently, the team at B. Carlson Heating, Air Conditioning & Plumbing completed a full HVAC system replacement for a local homeowner—installing a modern, energy-efficient Amana system built to handle New Mexico’s unique climate year-round.
Job Overview
- Location: Albuquerque, NM
- Scope: Full system replacement including furnace, evaporator coil, and condenser
- Equipment:
- Amana 80% AFUE AR9T80 Series Gas Furnace
- CAPTA Series Evaporator Coil with TXV – AlumaFin7, R-32
- Amana 15.2 SEER2 3.5 Ton AC Condensing Unit
- Why it mattered: The existing system was no longer providing consistent performance or efficiency. Upgrading the system ensured reliable heating and cooling, lower utility costs, and readiness for future energy demands.
What We Found
During the initial assessment, our technicians evaluated the homeowner’s existing furnace, evaporator coil, and condenser. The system was aging and inefficient, struggling to maintain stable indoor temperatures. The ductwork and electrical components required updates to support modern equipment, and refrigerant testing showed the system was no longer operating within manufacturer specifications. These factors made a full system replacement the most cost-effective and long-term solution.
The Solution
Our installation team completed the replacement over two days, following Amana’s installation specifications and local Albuquerque code requirements. The process included:
- Removing the old furnace, coil, and condenser safely and preparing the site for new equipment
- Installing the new Amana 80% AFUE furnace and cased evaporator coil inside the existing closet, ensuring a precise fit and proper airflow
- Setting the new 3.5-ton Amana 15.2 SEER2 condenser on a level pad with a new disconnect and proper clearances
- Running and sealing updated refrigerant lines and electrical connections
- Pressure testing the system above 500 psi, vacuum testing below 500 microns, and performing decay tests to confirm system integrity
- Verifying static pressure and temperature splits at multiple registers throughout the home
