HVAC Services in Minneapolis, MN
Beltrami Air & Heating handles the full range of residential and commercial HVAC work across the Minneapolis–St. Paul metro area — from emergency furnace repairs in the middle of a Minnesota winter to planned system replacements and seasonal tune-ups. Below is a breakdown of what we do, the equipment we support, and how we approach each job.
Furnace Installation & Repair
Natural gas, propane, and electric furnaces for Minneapolis homes and businesses. We handle full replacements, heat exchanger repairs, ignition and flame sensor issues, blower motor service, and emergency no-heat calls. Proper sizing and airflow setup are standard on every install.
- High-efficiency 80% and 90%+ AFUE equipment
- Heat exchanger inspection and replacement
- Ignition, flame sensor, and control board repair
- Emergency no-heat response
Central Air Conditioning
Central AC replacement and repair sized for real Minnesota cooling loads. We diagnose refrigerant issues, compressor failures, capacitor and contactor problems, and coil freeze-ups. New systems are matched to your existing ductwork and load profile for efficient, even cooling.
- 14 SEER to high-efficiency inverter systems
- Refrigerant leak detection and recharge
- Compressor, capacitor, and contactor replacement
- Coil and condensate drain service
Heat Pump Systems
Cold-climate heat pumps that deliver both heating and cooling from a single unit. We size for Minnesota heating demand, verify backup heat integration, and configure controls so the system hands off cleanly when temperatures drop. A strong option for electrification and efficiency upgrades.
- Cold-climate rated heat pump selection
- Dual-fuel and backup heat integration
- Defrost cycle and reversing valve service
- Balance point evaluation
Boiler Service
Hot water and steam boiler repair, replacement, and maintenance for older Minneapolis homes with radiator and in-floor systems. We service gas and oil boilers, address circulation and pressure issues, and recommend efficient replacements when a unit has reached end of life.
- Cast iron and mod-con boiler replacement
- Circulator, zone valve, and aquastat repair
- Pressure relief and expansion tank service
- Radiator and in-floor zoning
Ductwork Design & Sealing
Duct inspection, sealing, and modification to fix uneven temperatures and reduce energy waste. Many Twin Cities homes have undersized or leaky duct runs. We measure airflow, seal leaks, add returns where needed, and balance the system so every room gets conditioned air.
- Duct leakage testing and mastic sealing
- Return air and supply run modification
- Air balancing for even temperatures
- Duct cleaning and inspection
Ventilation & Indoor Air Quality
Whole-home ventilation, filtration, and humidity control tailored to Minnesota’s tightly built homes. We install and service HRVs and ERVs, media filtration, UV treatment, and whole-house humidifiers to keep indoor air healthy through sealed-up winters and humid summers.
- HRV and ERV installation and service
- MERV 11–16 media filtration upgrades
- Whole-house humidifier and dehumidifier service
- UV and bipolar ionization treatment
Seasonal Maintenance Programs
Spring cooling and fall heating tune-ups that keep equipment running efficiently and catch small problems before they become mid-season failures. Our maintenance visits include a full performance checklist, safety checks, and a written record of condition.
- Spring AC tune-up and winterization
- Fall furnace safety and efficiency check
- Filter, belt, and component inspection
- Priority scheduling and written service record
Equipment, Sizing & Diagnostic Methods
Equipment Brands Supported
We install and service equipment from major manufacturers including Carrier, Trane, Lennox, Rheem, American Standard, Bryant, and Goodman. Brand choice is based on your building, budget, and reliability history in the Minneapolis climate — not sales quotas. We’ll recommend what fits, whether that’s a premium high-efficiency unit or a dependable mid-range system.
System Sizing Methodology
Every replacement starts with a proper load calculation, not a rule of thumb. We evaluate insulation, window area, ceiling height, occupancy, and orientation to size equipment for real heating and cooling demand. Oversized systems short-cycle and fail to dehumidify; undersized ones can’t keep up on the coldest days. Right-sizing matters in Minnesota.
Diagnostic Approach
We diagnose before we replace. Using manifold gauges, combustion analyzers, temperature rise and delta-T measurements, and electrical testing, we identify the actual failure point. Common Minneapolis-area issues — frozen coils from low airflow, cracked heat exchangers from age, short cycling from oversized equipment — each have specific root causes we trace before recommending a fix.
