A & Z Mechanical's Services
A & Z Mechanical is a full-service HVAC contractor serving Colorado Springs and El Paso County. Our Mechanical Class A Licensed comfort advisors are not paid on commission — so every recommendation we make is based on what your home actually needs, not what generates the biggest invoice.
Air Conditioning Services
AC repair, AC installation, AC replacement, and seasonal tune-ups. High-efficiency system installations sized correctly for Colorado Springs’ elevation, with expertise in the 2025 R-454B refrigerant transition. Emergency AC repair available 24 hours a day, 7 days a week.
Heating Services
Furnace repair, furnace installation, furnace replacement, and pre-season tune-ups — all with altitude-specific diagnostics built into every call. At 6,035 feet, Colorado Springs furnaces burn fuel differently than at sea level. We perform carbon monoxide testing on every heating service call and apply altitude adjustments on every installation. As a Armstrong Air Authorized Dealer, we install manufacturer-backed systems with full warranty protection.
Whole House Humidifiers
Colorado Springs’ annual relative humidity frequently falls below 20% — lower than most desert climates — and standard forced-air heating makes it worse every winter. Whole-home bypass, fan-powered, and steam humidifiers integrate directly with your existing HVAC system to protect hardwood floors, furniture, and respiratory health all season. Service and water panel replacement for installed systems also available.
Whole House Air Purifiers
Colorado’s June–September wildfire season pushes smoke and fine particulate matter across the Front Range every year. HVAC-integrated whole-home air purifiers with MERV 13–16 filtration and activated carbon media clean the air in every room, every time your system runs — not just one room with a portable unit. Installation and filter replacement for all makes and models.
Aeroseal Duct Sealing
A & Z Mechanical is one of the only Aeroseal certified contractors in El Paso County. Aeroseal seals duct leaks from the inside using a DOE and EPA-backed pressurized polymer process — no demolition, no wall openings. Results include up to 90% reduction in duct leakage, lower energy bills, eliminated hot and cold spots, improved indoor air quality, and a printed before-and-after measurement report. Backed by a 10-year warranty.
Unico Systems
A & Z Mechanical is the only certified Unico installer in Colorado Springs. Unico small-duct high-velocity HVAC systems deliver whole-home heating and cooling through two-inch flexible tubing — without soffits, without wall demolition, without compromising your home’s architecture. The right solution for historic homes in Old Colorado City and Manitou Springs, older properties, Broadmoor estates, home additions, and any space where conventional ductwork isn’t feasible.
Maintenance
Pre-season furnace and AC tune-ups, priority scheduling, filter replacement, carbon monoxide testing, and member discounts on repairs — from comfort advisors who are not paid on commission. Available year-round for residential and light commercial properties throughout El Paso County. A standalone one-time seasonal tune-up is also available for homeowners who want professional service without a program commitment.
