Heat pump and mini split installation in Hillsboro typically runs $3,500-$7,500, with most retrofits in the 97124 corridor requiring a duct audit first. We’re Heat Pump & Mini Split in Hillsboro within the hour from our dispatch, and we know the Tualatin Valley floor well enough to spec systems that handle your winter inversions without callbacks. Call (866) 561-3358 - a live person answers, day or night.
We’ve been at this since 2018. That’s long enough to remember when Hillsboro’s 97124 zip was still farmland, and long enough to have worked on hundreds of the tract homes built during Intel’s boom years. Those houses were engineered to Pacific Northwest standards that assumed you’d never need cooling. The June 2021 heat dome changed that assumption for good. Now we’re retrofitting heat pumps into homes that were never designed for the airflow they require, and we’ve learned exactly where the builders cut corners.
Why Fireside Heating & Air Co. Is Hillsboro’s Preferred Heat Pump & Mini Split Company
Hillsboro homeowners don’t call us for the lowest bid. They call us because their neighbor in Tanasbourne did, or because they found us after a franchise outfit short-cycled a heat pump into their Orenco Station duct system and walked away. We’ve earned our reputation here one house at a time, and we back every job with the 90-Day Done Right Promise - in writing, no paperwork, no arguing.
Our technicians are background-checked, uniformed journeymen who put on shoe covers without being asked. They treat your home the way they’d treat their mother’s. Most jobs finish in a single visit. When you call (866) 561-3358, you reach a live person - not a voicemail tree, not an answering service in another state. That’s been true since Glen Hartman founded Fireside in 1984, and it’s true at 2 a.m. on a Sunday when your heat pump locks out on a cold inversion night.
We know Hillsboro’s housing stock intimately. The 1,500-2,500 square foot single-family tracts north of Baseline, built roughly 1993-2008, with their original single-speed gas furnaces and return systems sized purely for heating. The older 97123 areas near historic downtown, with mid-century homes from the 1950s-60s whose undersized, leaky ducts need modification before any heat pump will work properly. This isn’t theoretical knowledge. We’ve crawled through the attics. We’ve measured the static pressure. We’ve fixed the callbacks other companies generated.
Our Heat Pump & Mini Split Services in Hillsboro
Heat Pump Installation
This is where Hillsboro’s 1990s-2000s tract homes need the most careful work. The Intel-boom subdivisions of 97124 are full of single-speed furnaces paired with duct systems that have no return air in secondary bedrooms and significant attic leakage. Skip the duct pressure test, and your new heat pump will short-cycle, wear out prematurely, and never deliver the comfort you paid for. We make the duct audit a near-mandatory first step on these jobs. A typical heat pump installation in Hillsboro runs $3,500-$7,500, with duct modifications adding to that figure when needed. The price we quote is the price you pay.
Ductless System & Mini Split Install
For Hillsboro homes where the duct system is too compromised to salvage - or where there never was one to begin with - a ductless mini split is often the straightest path to both heating and cooling. We’ve installed Daikin and Carrier ductless systems in historic downtown 97123 bungalows, in Tanasbourne townhomes with no attic access, and in Orenco Station additions where the original HVAC was never extended. No ductwork means no duct leakage, no airflow balancing nightmares, and no tearing open walls. A single outdoor unit can serve four or more indoor heads, each with its own thermostat.
Multi-Zone System
Hillsboro’s older homes with additions, or the split-level designs common in 1990s subdivisions, often develop severe temperature imbalances. A multi-zone mini split lets you heat the downstairs living area to 68 while the upstairs bedrooms stay at 72, or cool the west-facing master bedroom independently from the rest of the house. In the Tualatin Valley, where summer evenings can stay warm well past sunset while the valley floor cools, that independent control matters. We size each zone based on actual load calculations, not rules of thumb.
Heat Pump Repair & Mini Split Repair
When your heat pump locks out on a 28-degree Hillsboro morning, or your mini split throws an error code in the middle of a July heat wave, you need someone who answers the phone and knows how to diagnose it. Our technicians carry common parts for Rheem, York, Daikin, Bryant, and the other major brands we service. Most repairs in Hillsboro are same-day. We offer $50 off any repair over $250, and we’ll give you a free second opinion on any written estimate you’ve already received.

Trusted Brands We Service in Hillsboro
We’re trained to service nine major residential brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Hillsboro customers, that means we stock the parts that fail most often locally - capacitors and contactors for the aging single-speed furnaces still common in 97124, low-ambient kits for heat pumps that need to perform through valley inversions, and refrigerant linesets sized for the longer runs common in suburban lots. We don’t have to order everything from Portland and make you wait. Most jobs, we’ve got what we need on the truck.
Common Heat Pump & Mini Split Problems We See in Hillsboro Homes
- Duct systems designed only for heating airflow cannot handle a heat pump’s higher CFM requirements. In 97124 tract homes, we’ve measured static pressure so high the compressor short-cycles within minutes. The fix isn’t a bigger heat pump - it’s fixing the ducts first, or going ductless.
- No return air in secondary bedrooms creates hot and cold spots that get worse in cooling mode. That master bedroom with no return? It pressurizes, forcing conditioned air out through every crack and leaving you sweating at 2 a.m. We add dedicated returns where the original builder skipped them.
- Attic duct leakage in 1990s-2000s homes bleeds 20-30% of your efficiency into the insulation. On cold inversion nights, that can mean your heat pump simply cannot reach setpoint. We seal with mastic and proper mechanical fasteners, not tape that dries and falls off.
- Original thermostats and wiring from the gas-furnace era often can’t communicate with modern heat pump stages. We see this constantly in Hillsboro’s Intel-era homes: a two-stage heat pump wired to a single-stage stat, running at half capacity forever or not at all. We upgrade the control package as part of the installation, not as a surprise add-on.

FAQs - Heat Pump & Mini Split in Hillsboro
Because the duct systems were engineered for gas furnace airflow, not heat pump airflow, and most have no return air in secondary bedrooms plus significant attic leakage. In an Orenco Station home built in 2001, we found the original single-speed gas furnace (a 60k BTU Goodman) paired with a leaky flex-duct system that had no return in the master bedroom. We installed a 3-ton Carrier 38MURA heat pump and upgraded the supply duct runs to handle the higher airflow, adding a dedicated return. The homeowner now reports balanced temps across all three bedrooms for the first time. Call (866) 561-3358 and we’ll audit your ducts before quoting any heat pump work.
Usually, yes - but only if your duct system can handle the higher airflow and your electrical panel has the capacity. Most 2003 Tanasbourne and 97124 homes have 150-amp service, which is often tight for a heat pump addition. We check this during our free estimate. If the ducts won’t cooperate, we’ll tell you straight and quote a ductless alternative. No point in selling you a system that short-cycles.
Most installations take one to two days, with permitting through the City of Hillsboro adding three to five business days beforehand. We handle the permit application as part of our service. If your home needs duct modifications - common in 97124 - we add a day. We schedule the work when we say we will, and we finish when we say we will. Call (866) 561-3358 to get on the calendar.
Yes, when properly spec’d for low-ambient operation. Hillsboro sits on the Tualatin Valley floor where cold air pools during inversions, routinely dropping several degrees below Portland proper. We install Daikin and Carrier hyper-heat models rated to perform at sub-zero temperatures, not standard units that lock out when you need them most. The key is matching the outdoor unit to your actual design temperature, not the manufacturer’s headline number.
Sometimes, but we usually recommend upgrading. Most Hillsboro homes from the 2000s have single-stage thermostats that can’t communicate with modern two-stage or variable-speed heat pumps. We install the correct control package so your system actually delivers the efficiency you paid for. The thermostat is included in our installation quote - not an add-on surprise.
