Ductless mini-split systems are one of the fastest-growing cooling solutions in Albuquerque — and for good reason. The city has a higher-than-average share of older homes without ductwork, detached casitas that need independent climate control, and room additions that central AC can't reach. A ductless system solves all three. Number One Plumbing, AC, Solar & Electric installs and services all major mini-split brands throughout Albuquerque — from single-zone systems for a guest casita to multi-zone installations that cool an entire home. Licensed technicians, 20 years in this market, same-day repair available. Call (505) 999-9567 or request service below.

Mini-Split Installation
We install single-zone and multi-zone ductless systems for homes, casitas, additions, garages, and commercial spaces throughout Albuquerque. Every installation includes proper sizing, correct refrigerant line placement, electrical work, and full commissioning before we leave.
Mini-Split Repair
When your ductless system stops cooling, produces error codes, leaks water, or loses efficiency we diagnose and fix it fast. We service all major brands and carry common parts on our trucks for same-visit repairs.
Mini-Split Maintenance
Annual mini-split maintenance keeps ductless systems running efficiently and prevents premature failures. We clean the indoor air handler filters and coils, inspect the outdoor unit, check refrigerant pressure, and test electrical components. Albuquerque's dust environment means ductless filters need more frequent attention than in other climates.
Multi-Zone System Design
Multi-zone systems connect multiple indoor units to one outdoor compressor, providing independent temperature control for different rooms or spaces. We design and install multi-zone systems correctly — matching indoor unit capacity to room load and outdoor unit capacity to the total system demand.

Casitas and guest houses
Albuquerque has one of the highest concentrations of detached casitas in the Southwest. A ductless system is almost always the right answer for a casita — it provides independent climate control without tying into the main home's ductwork or HVAC system.
Older homes without ductwork
Many Albuquerque homes built before the 1970s have no existing ductwork. Installing central AC in these homes requires significant ductwork construction. A ductless system provides whole-home or zone cooling without the disruption and cost of adding ducts.
Room additions
When a room addition extends beyond the reach of existing ductwork, a mini-split is typically the cleanest, most efficient solution. No duct extension, no blower sizing issues, just a properly sized unit for the space.
Garages and workshops
Home garages and workshops that need cooling for year-round use are ideal mini-split applications. A single-zone system handles the space efficiently without impacting the main home's AC load.
Supplemental cooling for problem rooms
Some rooms in Albuquerque homes — particularly south-facing rooms with large windows or rooms above garages — never cool adequately with central AC. A single-zone mini-split targeted at that room solves the problem without upgrading the entire central system.
Converting from swamp cooler
Homeowners who want to upgrade specific zones from evaporative cooling to refrigerated air without a full whole-home conversion often choose ductless for targeted rooms while maintaining swamp cooler coverage elsewhere.

We install and service all major residential and light commercial ductless brands:
Mitsubishi Electric — the most widely installed ductless brand in Albuquerque. Known for reliability, quiet operation, and industry-leading efficiency ratings. Our technicians are experienced with the full Mitsubishi product line.
Daikin — excellent efficiency ratings and strong warranty support. A growing presence in the Albuquerque market.LG — competitive efficiency and a wide range of single and multi-zone configurations.
Samsung — strong performance in heat pump applications, good choice for year-round heating and cooling.
Carrier, Trane, Lennox, Rheem — all major HVAC manufacturers offer ductless lines we install and service.If your brand isn't listed, call us — we service virtually all ductless systems with parts readily available in the Albuquerque market.
The Uno Care Club includes ductless mini-split maintenance as part of whole-home membership — annual indoor unit coil and filter cleaning, outdoor unit inspection, refrigerant pressure check, and electrical component testing. Scheduled before cooling season so your system is ready when Albuquerque temperatures climb.
Members receive priority scheduling during peak summer heat, one-year repair protection on completed work, and installation credits up to $600 annually that bank toward future equipment upgrades — up to $3,000 maximum.

System won't turn on or loses power
Could be a tripped breaker, failed capacitor, communication error between indoor and outdoor units, or control board issue. We diagnose the root cause on the first visit.
Indoor unit not cooling or heating
Low refrigerant, dirty coil, or failing compressor. Refrigerant leaks are more common in older systems and should be repaired rather than just recharged.
Error codes on the display
Most mini-split brands display error codes that indicate specific faults. We interpret the code, diagnose the underlying issue, and repair it — not just clear the code and hope it doesn't come back.
Water dripping from the indoor unit
A clogged condensate drain line or improperly pitched installation. In Albuquerque's dusty environment, drain lines in ductless systems accumulate debris faster than in cleaner climates.Unusual noisesRattling, grinding, or squealing from the indoor or outdoor unit indicates a specific mechanical issue. Addressed early these are minor repairs.
Reduced airflow from indoor unit
Almost always a dirty filter or coil. In Albuquerque's dust environment, ductless filters can clog faster than the manufacturer's cleaning interval suggests. Monthly filter cleaning during peak season is recommended.

What is a ductless mini-split system?
A ductless mini-split is a heating and cooling system that doesn't require ductwork. It consists of an outdoor compressor unit and one or more indoor air handler units mounted on the wall or ceiling. Refrigerant lines connect the outdoor and indoor units through a small hole in the wall. Each indoor unit cools or heats the space it's in independently — allowing different temperatures in different rooms.
How much does ductless mini-split installation cost in Albuquerque?
Single-zone installation costs vary depending on the system capacity, brand, and complexity of the installation — particularly how far the indoor and outdoor units are from each other and what electrical work is required. Multi-zone systems cost more due to the additional indoor units and refrigerant lines. We provide a detailed written estimate before any work begins. Call (505) 999-9567 for a free assessment.
Can a mini-split both heat and cool?
Yes. Most modern mini-split systems are heat pumps — they provide both heating and cooling from the same system. In Albuquerque's climate a heat pump mini-split can handle heating effectively for most of the year, though very cold nights may require supplemental heating for some applications.
How long do ductless mini-splits last?
With proper maintenance, ductless mini-split systems typically last 15 to 20 years. Annual maintenance — primarily cleaning the indoor coils and filters and checking the outdoor unit — significantly extends system life. Albuquerque's dust environment makes regular filter cleaning especially important.
Can I install a mini-split in my casita?
Yes — a ductless mini-split is almost always the best solution for a detached casita. It provides independent climate control, is relatively easy to install without major construction, and operates efficiently for a smaller space. Single-zone systems sized appropriately for a casita are one of our most common installations.
Do ductless systems work well in Albuquerque's climate?
Very well. Mini-splits are highly efficient in Albuquerque's dry climate and handle the temperature swings between hot days and cool nights effectively. Heat pump models provide both summer cooling and winter heating — particularly useful for casitas and additions that need year-round climate control without a separate heating system.
How often should I clean my mini-split filters?
Monthly during peak cooling and heating season — more frequently if you have pets or live in a particularly dusty area. Albuquerque's desert environment means filters accumulate dust faster than the manufacturer's typical cleaning interval. Most indoor units have washable filters that take about five minutes to clean.
