We’ve been driving to Mount Prospect since 2018. We know the split-levels east of Route 83 where the family room never warms up, the ranches near Elmhurst Road with original 1960s ductwork, and the raised-ranches around Rand Road that need creative zoning solutions. That familiarity matters. When your heat pump fails on a zero-degree January night or your mini split starts blowing musty air in July humidity, you want a crew that understands your house before they walk through the door.
Why Fireside Heating & Air Co. of Chicago Is Mount Prospect’s Preferred Heat Pump & Mini Split Company
Forty-two years in this trade teaches you which villages keep their homes for generations. Mount Prospect is one of them.

In writing. No paperwork, no arguing.

Our Heat Pump & Mini Split Services in Mount Prospect
Heat Pump Repair
Heat pump repair in Mount Prospect runs $150-$650 depending on what’s failed. The most common call we get is a unit that won’t switch out of auxiliary heat mode, which spikes your ComEd bill fast. In Mount Prospect’s climate, with Arctic air masses pushing design heating days to their limits, a heat pump running on strips is working twice as hard for half the result. We carry diagnostic tools and replacement parts for Carrier, Trane, Lennox, and Goodman systems, and most repairs are done same-day.
Heat Pump Installation
A full heat pump installation in Mount Prospect typically falls in the $3,500-$7,500 range. But here’s what separates a good install from a callback: Manual J load calculation. Mount Prospect sits on the northwest Cook County plain with no geographic buffer from Canadian cold fronts. Undersized equipment won’t keep up on the coldest nights. Oversized equipment short-cycles and dies young. We measure every room, account for your home’s insulation and air leakage, and size it precisely. For the ranch homes built 1955-1975 that dominate Mount Prospect’s 60056 zip code, we also evaluate whether your legacy ductwork can handle modern variable-speed equipment. Often, it can’t.
Mini Split Install
Mini split installation is where Mount Prospect’s housing stock becomes an opportunity instead of a limitation. In split-level homes east of Route 83 - the ones built between 1958 and 1965 - the sunken family room stays frigid all winter while upstairs bedrooms overheat. Standard single-zone installs don’t fix this. We design multi-zone systems with dedicated returns and damper zoning that balance temperatures across half-floors. On a raised-ranch in the Elmhurst Road corridor east of Route 83, our crew replaced a failing 1980s Lennox heat pump with a two-zone mini split system. The original ductwork had no return in the sunken family room, so we added a dedicated return from that level and installed a Daikin multi-zone to handle the chronic cold-spot issue. The homeowners reported even temperatures for the first time in twenty years.
Mini Split Repair
Mini split repair covers everything from refrigerant leaks to fouled blower wheels. In Mount Prospect, we see a specific summer failure mode: uninsulated ducts in unconditioned crawlspaces sweat in July’s high dew-point humidity, often 70°F or higher. That moisture breeds mold that migrates into mini split coils and blower assemblies. The system doesn’t fail all at once - it gets louder, smells musty, and cooling capacity drops. We clean coils, replace blower wheels, and seal ductwork to stop the source. Most mini split repairs in Mount Prospect are completed in under three hours.
Multi-Zone System
Multi-zone systems are our recommended approach for Mount Prospect split-levels and raised-ranches. Instead of forcing one thermostat to govern stacked half-floors with different sun exposure and duct runs, we install independent heads with individual controls. The upfront cost runs higher than a straight swap, but the elimination of chronic comfort complaints - and the callbacks they generate - makes it the right long-term value. We size each zone independently and commission the system with airflow verification.
Ductless System
Ductless systems bypass Mount Prospect’s legacy ductwork entirely. For homes where the original ducts are too deteriorated, too small, or too poorly routed to remediate, we mount compact outdoor units and run refrigerant lines through walls to indoor heads. No demolition, no chasing ducts through finished basements. We install Daikin and Carrier ductless systems with inverter-driven compressors that modulate output instead of cycling on and off, which saves wear and keeps humidity under control during Mount Prospect’s sticky July afternoons.

Trusted Brands We Service in Mount Prospect
We train our technicians on nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard.

If you’re running an older Goodman or Rheem, we know the failure patterns and keep the replacement boards on hand. Fast turnaround matters when your house is cold.
Common Heat Pump & Mini Split Problems We See in Mount Prospect Homes
- Short-cycling mini splits in split-level family rooms. In homes built 1958-1965 east of Route 83, the sunken family room has no return air path. The mini split reaches setpoint quickly because the space is small, then shuts off before warming the whole level. It restarts ten minutes later. We add dedicated returns or relocate the head - never just swap the unit.
- Static pressure trips on variable-speed heat pumps. Mount Prospect ranches from the 1950s and 1960s have ductwork engineered for low-static, high-BTU furnaces that no longer exist. Modern heat pumps need higher airflow volumes at lower resistance. When we encounter undersized ducts - often 6-inch round supplies where 8-inch is needed - we either upsize the trunk or recommend ductless.
- Mold-fouled blower wheels from sweating crawlspace ducts. July in Mount Prospect brings dew points that soak uninsulated metal ducts in crawlspaces. That moisture feeds mold that gets drawn into mini split indoor units. The first sign is a musty smell; the last sign is a seized blower motor. We clean, treat, and seal - or bypass the duct entirely with ductless.
- Refrigerant leaks in aging copper linesets. Original heat pump installations from the 1980s and 1990s used copper lines buried in walls or run through concrete. After thirty years, pinhole leaks develop. We pressure-test, locate with electronic detectors, and replace linesets - sometimes requiring creative routing through closets or soffits to avoid opening finished walls.
Pricing for Heat Pump & Mini Split in Mount Prospect, IL
Here’s what heat pump and mini split work costs in Mount Prospect. These are real ranges based on jobs we’ve completed in 60056 - not teaser rates that change once we’re in your home.

What moves the needle within these ranges? For repairs, it’s parts - a capacitor is $150-$250 installed, a compressor replacement pushes toward $650. For installation, it’s zones and ductwork condition. A single-zone ductless mini split on an exterior wall with easy electrical access sits at the lower end. A four-zone multi-zone system with dedicated returns in a split-level, plus electrical upgrades, moves toward the upper end. We quote upfront, in writing, before any work begins.

FAQs - Heat Pump & Mini Split in Mount Prospect
Yes - a properly zoned mini split with a dedicated return can fix that cold family room without opening walls. We run refrigerant lines through exterior walls or soffits, mount the indoor head on the family room wall, and add a return path from that level. In Mount Prospect split-levels east of Route 83, this is our standard approach rather than an upgrade. Call (833) 983-1671 and we’ll walk through your floor plan - estimates are free.
Not always, but it must be evaluated. Original Mount Prospect ranch ductwork from the 1960s was sized for low-efficiency, high-temperature furnaces. Modern heat pumps need more airflow at lower static pressure. We measure with a manometer. If your ducts test within range, we adapt. If they’re undersized or leaky in unconditioned spaces, we quote remediation separately - or recommend ductless if the cost to re-duct exceeds the value. Call for a free assessment.
Telltale signs: ice on the outdoor coil in summer, hissing near the lineset, rising electric bills, or the system blowing cool-not-cold air. We pressure-test with nitrogen and use electronic leak detectors to pinpoint the source. In Mount Prospect, we still repair refrigerant leaks on systems less than fifteen years old if the coil is intact. On older units with degraded copper or obsolete refrigerant, we give straight talk about repair versus replace. Call (833) 983-1671 - we’ll test it and tell you exactly what we find.
Yes - the Village of Mount Prospect requires permits for all HVAC equipment installations, including mini splits and heat pumps. We pull the permit as part of our standard process, schedule inspections, and handle the paperwork. You don’t chase the village clerk or wait in line. The permit fee is included in our quoted price, not added later. We’ve worked with Mount Prospect building inspectors for decades; we know the local amendments to the mechanical code and spec our installs to pass the first time.
Yes - zoning is the right fix for that exact problem, and it’s especially effective in Mount Prospect’s split-level and raised-ranch stock. We install motorized dampers in your ductwork or, more often, a multi-zone mini split with independent heads per floor. Each zone has its own thermostat and temperature target. The upstairs stops overheating. The basement stops freezing. Your system stops working against itself. Most zoning retrofits in Mount Prospect are done in one day. Call (833) 983-1671 for a free estimate - we’ll show you the layout before we start.
