Why Gresham Homeowners Call Us

ThermexaPro has been running HVAC Service in Gresham since 2023, and in that time we have worked on just about every kind of system this city has. Gresham's housing stock is genuinely diverse: you have 1920s bungalows near Main City Park, mid-century ranches out toward Gresham East, and newer construction in the 97080 ZIP code that still uses builder-grade Goodman and Rheem equipment. That mix means we see everything from R-22 systems that need a recovery machine to brand-new Mitsubishi Electric heat pumps that just need a thermostat dialed in. As an affordable HVAC contractor in Gresham OR, we keep our trucks stocked with the parts that fail most often here: capacitors, contactors, blower motors, and common igniters. If you search for HVAC Service near Gresham and want a straight answer instead of a sales pitch, call us at (855) 947-9500.

Gresham sits at the mouth of the Columbia River Gorge, which means colder winters and hotter summer afternoons than Portland proper. That temperature swing is hard on equipment. We see more frozen evaporator coils in spring and more ignition failures in January than our crews working closer to Milwaukie. The city also has a lot of older homes with original sheet metal ductwork that leaks 20 to 30 percent of conditioned air before it reaches a bedroom. We serve Gresham because the demand is real and the housing stock rewards a contractor who actually understands it.

HVAC Services We Run in Gresham

Gresham generates a steady mix of emergency calls and planned replacements, and we staff for both. If you need 24/7 HVAC Service Gresham OR because your heat pump locked out at 2 a.m., we answer. If you are planning a pre-summer AC tune-up before the first 90-degree week, we schedule that too. Here is what we actually do in this city.

01
␁

furnace repair

Gresham furnace repair usually means a failed igniter, a cracked heat exchanger, or a flame sensor that needs cleaning. We carry parts for Carrier, Trane, Lennox, and Goodman furnaces on every truck. Most no-heat calls in 97030 and 97080 get fixed in one visit, usually under two hours.

air conditioning repair

AC repair in Gresham spikes hard in July and August. The most common failures we see are blown capacitors, dirty condenser coils packed with cottonwood seed, and low refrigerant from a slow leak. We pressure-test with manifold gauges, find the leak, and recharge with R-410A.

furnace replacement

A lot of Gresham homes still run 20-year-old furnaces that are one repair away from replacement. We size the new unit to the house, not to the old one, and we check duct static pressure before we set anything. Most replacements are done in a single day.

air duct cleaning

Older Gresham homes with original sheet metal ductwork collect decades of dust, pet hair, and construction debris. We run a duct cleaning vacuum through the whole system, seal visible leaks with mastic, and replace fiberglass duct insulation where it has collapsed. You will notice better airflow at the far registers.

heating repair

Heating repair in Gresham covers furnaces, heat pumps, and the occasional boiler. When we get a no-heat call, we test the thermostat first, then the control board, then the ignition sequence. Nine times out of ten the problem is in one of those three places, and we can prove it with a multimeter before we quote anything.

heat pump repair

Heat pumps are common in newer Gresham construction, especially the 97080 subdivisions. We service Mitsubishi Electric and Daikin systems, diagnose reversing valve failures, and check defrost board operation. A heat pump that ices up in winter is usually a defrost sensor or a low charge, not a dead compressor.

emergency HVAC repair

When your heat dies at 11 p.m. in January, you want an emergency HVAC contractor near Gresham who actually picks up. We run after-hours dispatch for Gresham North and Gresham South, and we keep a stocked truck on call. No overtime surprise on the diagnostic.

AC repair

AC repair in Gresham East often comes down to airflow. Shaded lots near Main City Park hold moisture, and condenser coils grow a mat of pollen and grass clippings that chokes the system. We pull the coil, wash it out, and check the charge. Cooling comes back the same day.

heating and cooling repair near me

If you are typing heating and cooling repair near me into your phone, you want someone close. Our Gresham crews work out of the east metro, so we are usually 20 to 40 minutes out depending on traffic on Powell or Division. We text you an ETA and the tech's name before we roll.

ventilation system maintenance

Gresham homes built tight in the last 15 years need mechanical ventilation to stay healthy. We inspect bath fans, HRV and ERV cores, and dryer vents. A clogged ERV core will leave your house stuffy and humid all winter, and it is a 30-minute fix once we get to it.

hvac maintenance

Our Gresham maintenance plan covers two visits a year: a pre-summer AC tune-up and a winter furnace tune-up. We clean the flame sensor, check capacitor microfarads, test the condensate pump, and swap your air filter. Customers on the plan get priority scheduling when something breaks.

hvac replacement

Full HVAC replacement in Gresham means matching a new furnace and coil to your existing ductwork and line set. We measure static pressure, check return air sizing, and confirm the electrical panel can handle the new equipment. Most jobs are permitted and inspected, and we handle the paperwork.

AC installation

AC installation in Gresham is not just dropping a condenser on a pad. We set the unit level, braze the copper tubing with nitrogen flowing, pull a deep vacuum with a vacuum pump, and verify subcooling before we call it done. That is how you get a system that lasts 15 years instead of 8.

Heat pump repair

Heat pump repair in the Gresham hills often involves defrost issues and auxiliary heat strips that never got wired correctly. We check the reversing valve, the outdoor sensor, and the sequencer. If the strips are pulling 60 amps when they should pull 30, we find out why.

Air conditioner replacement

When your old R-22 air conditioner finally gives out, replacement is usually the smarter call. We haul the old unit away, dispose of the refrigerant through a recovery machine per EPA Section 608, and install a new R-410A system sized to your home. Most swaps are done in a day.

◒

Smart thermostat installation

We install Nest and Ecobee thermostats across Gresham, and we do the C-wire right the first time. A lot of DIY installs fail because the old furnace does not have a common wire, and the thermostat battery dies in a month. We run the wire and configure the staging properly.

Same-day HVAC service

Same-day HVAC service in Gresham is our default, not a premium add-on. Call before noon and we will almost always have a tech at your door that afternoon. We stock the common parts so we are not making a second trip for a $12 capacitor.

Furnace maintenance

Furnace maintenance in Gresham should happen every fall, before the first cold snap. We pull the burners, clean the flame sensor, inspect the heat exchanger for cracks, and check the inducer motor amp draw. Catching a cracked heat exchanger in October is a lot cheaper than catching it in January.

␁

pre-summer AC tune-up

A pre-summer AC tune-up in Gresham means cleaning the condenser coil, checking capacitor values, testing the contactor, and verifying the refrigerant charge. We do this in May and June so you are not the person calling on the first 95-degree day when every shop is booked out.

↯

winter furnace tune-up

Our winter furnace tune-up covers the full combustion side: gas pressure, flame sensor, igniter wear, and flue draft. Gresham winters push furnaces hard, and a unit that ran fine in October can start short-cycling by December. A tune-up catches that early.

AC repair near me

AC repair near me searches in Gresham usually come from the 97030 side, where the older homes have window units and central air that was added later. Those add-on systems often have undersized returns. We check airflow before we check the charge, every time.

heating and cooling near me

Heating and cooling near me in Gresham means you want one shop that handles both sides of the system. We do furnaces, AC, heat pumps, and the ductwork in between. One call, one invoice, one crew that knows your house.

central air repair

Central air repair in Gresham often traces back to a clogged condensate drain. The PVC condensate line runs to a floor drain or a pump, and when it clogs, the float switch shuts the whole system down. We clear the line and check the pan for cracks.

ac tune up

An AC tune up in Gresham is 60 to 90 minutes of real work: coil cleaning, capacitor testing, amp draw checks, and a refrigerant charge verification. We give you a written report with the actual numbers. If something is trending toward failure, you will know before it strands you in August.

How We Run HVAC Calls in Gresham

Gresham sits in Multnomah County, and every HVAC install or replacement we do here has to meet Oregon residential mechanical code and pull the right permit. We handle that paperwork. On the technical side, Gresham's clim

Older homes with leaky original ductwork
Gresham HVAC Service

Older homes with leaky original ductwork

Homes built before 1970 in Gresham North often have sheet metal ductwork with unsealed joints. That leaks 20 to 30 percent of your conditioned air into the crawlspace, so the furnace runs longer and the far bedrooms never get comfortable.

We pressure-test the duct system and seal accessible joints with mastic and mesh tape. Where fiberglass duct insulation has collapsed, we replace it. Most homes see a measurable airflow improvement at the farthest register after one visit.

Gorge wind and rapid temperature swings
Gresham HVAC Service

Gorge wind and rapid temperature swings

Cold air funnels through the Columbia River Gorge and hits Gresham harder than inner Portland. Furnaces short-cycle, heat pumps ice up, and ignition components wear out faster. We see more no-heat calls here in January than in most of the metro.

We tune combustion on every furnace visit, check heat pump defrost boards, and verify auxiliary heat staging. We also recommend a winter furnace tune-up in October or November so we catch worn igniters before they fail on the coldest night of the year.

Cottonwood seed and pollen clogging condensers
Gresham HVAC Service

Cottonwood seed and pollen clogging condensers

Late spring in Gresham means cottonwood seed drifting through the air and packing into AC condenser coils. A clogged coil drives head pressure up, kills capacitors, and can trip the system on high-pressure lockout during the first hot week of summer.

We pull the condenser fan, wash the coil from the inside out, and straighten bent fins with a fin comb. We also check capacitor microfarads while we are in there, because a weak capacitor is usually the next thing to fail after a hot-running coil.

Navigating Gresham: Landmarks We Use

Gresham is not a grid city, and the street layout changes block by block. Our techs use the major landmarks as orientation points so we can route efficiently and give you an accurate ETA. If you tell us you are near Gresham City Hall or off Burnside by Mount Hood Community College, we know exactly where to go. We also keep an eye on the MAX Blue Line corridor because it affects traffic on the main east-west streets during commute hours.

TGresham

Gresham City Hall

Gresham City Hall sits near the center of downtown and is a useful orientation point for calls in the historic core. If you are nearby, we know which cross streets to use and where to park without circling the block.

TGresham

Main City Park

Main City Park anchors the west side of downtown along the Springwater Corridor. Calls near the park usually mean older homes with crawlspace furnaces, and we route in from Powell or Main Street depending on the time of day.

TGresham

Mount Hood Community College

Mount Hood Community College sits on the north side of Gresham and is a clear landmark for calls in the surrounding residential streets. We use Kane Drive and 257th as our main approaches to that part of town.
