# Condo HVAC Repair Markham | Diagnostic from $185 URL: https://condohvacrepairtoronto.ca/locations/markham/ ![Technicians arriving at a Downtown Markham mid-rise condo](/images/misc/two-technicians-arriving-at-a-downtown-markham-mid.webp) Serving Markham & Nearby Neighbourhoods # Condo HVAC Repair in Markham, ON | Service Contracts, Heat Pump Repair & Unionville Mid-Rises Last updated: October 9, 2026 Condo HVAC Repair Toronto [/ →](/) looks after local condos mainly through annual service contracts, because that is what this building stock needs. Downtown Markham, Markham Centre, Unionville and Cornell are full of 2000s and 2010s mid-rises with a water-source heat pump in every suite, and those heat pumps fail in predictable ways when they are not serviced. Older stock is here too. Thornhill-Markham towers from the 1980s run hydronic fan coils, and Milliken mid-rises from the 1990s still have Magic-Pak units and early heat pumps. Unionville mid-rises from the 2000s are now at the age where contactors, reversing valves and hoses need attention. James Kowalski's team led the Downtown Markham 24-unit heat pump repair, where a quote for chassis replacements turned into a $14,200 valve and contactor job. That experience shapes how we run contracts here: catch the cheap parts before they fail, and only recommend replacement when the numbers support it. - Annual Service Contracts - Trane Axiom Experience - TSSA Certified - $5M CGL + WSIB - 1,500+ Units Serviced Call (647) 294-5454 [tel:+16472945454 →](tel:+16472945454) See Published Pricing [#pricing →](#pricing) Thanks, we have your request.

Fast Help Available ### Reversing valves sticking at changeover in Downtown Markham heat pumps What you notice: In May the suite keeps heating, or in October it keeps cooling, even with the thermostat set correctly. Why it happens here: Downtown Markham construction began in 2005, so its first towers now run water-loop heat pumps 15 to 20 years old, and skipped annual service lets solenoids and valves stick. What we do: Condo heat pump repair tests the solenoid coil and the valve, and a service contract adds spring and fall checks that catch it early. These four problems come up more in buildings here than anywhere else we work, because of the building ages and equipment in the area. ### Reversing valves sticking at changeover Every May and October, some heat pumps stay stuck in one mode. Often it is a solenoid coil, a quick fix. Sometimes the valve body needs replacing with refrigerant recovery and brazing. Fix: Solenoid from $280 ### Contactor failures in mid-season Contactors pit and burn after about 10 years of starts. Compressors stop or chatter in the middle of July. A contactor and capacitor swap usually costs a few hundred dollars, not a new chassis. Fix: Contactor from $320 ### Skipped maintenance shortening heat pump life Dirty filters, clogged strainers and scaled coaxial coils make heat pumps work harder and fail sooner. Annual service catches all three, for $185 to $240 per unit per year. Contract: from $185 per unit ### Magic-Pak end of life in 1990s stock Milliken and older Thornhill-Markham low-rises have Magic-Pak units reaching 25 to 30 years. We plan replacements with bulk pricing at 10 or more units and gas sign-off per suite. Replacement: $4,800-$7,500 Services ## Heat Pump and Service Contract Options Markham is mostly 2000s and 2010s heat pump mid-rises, where annual service contracts prevent seasonal failures. Our team runs those contracts and handles repairs. ![Two technicians with refrigerant gauges on a water-source heat pump in a North York condo closet](/images/misc/two-technicians-with-refrigerant-gauges-on-a-water.webp) ### Condo Heat Pump Repair $240 Diag Water-source heat pump service starts at a $240 diagnostic for suites in North York, Markham and Mississauga. We isolate loop-side faults from unit-side faults first, then test reversing valves, contactors, coaxial coils and pressure switches on ClimateMaster, Trane and Whalen chassis. Owners and facilities directors avoid condemning a unit that only needed a $650 repair. Locally: Our core service here: Trane Axiom and ClimateMaster repairs and contracts.

One visit per unit per year runs $185 to $240, two visits $320 to $420. For the 2000s and 2010s mid-rises, this is the cheapest way to avoid the mid-July contactor failures and changeover valve problems that fill our phones every season. Property managers get a per-suite report after each round. ### Trane Axiom and ClimateMaster repairs Downtown Markham and Markham Centre towers often run Trane Axiom water-loop heat pumps, with ClimateMaster in other buildings. We carry the common contactors, capacitors and solenoid coils for both. On the Downtown Markham 24-unit job, testing every unit's reversing valve and contactor in sequence meant the property manager paid $14,200 for repairs instead of replacing chassis that still had years left in them. ### Unionville mid-rise heat pump care Unionville's mid-rises from the 2000s are at the stage where hoses, strainers and coaxial coils need attention. Many still have rubber hoses. We replace them with braided stainless, clean strainers and descale coaxial coils where pressure readings show scale. Owners in owner-occupied Unionville buildings often book this together with a quieter ECM blower when the closet is close to a bedroom. ### Older fan coil and Magic-Pak stock Not all of the stock here is new. Thornhill-Markham towers from the 1980s have hydronic fan coils with the usual valve, motor and scale issues, and Milliken low-rises have 1990s Magic-Pak units. Our team handles these with the same written scope and price, including TSSA gas sign-off on Magic-Pak replacements. ![Technicians testing a reversing valve solenoid in a Unionville condo](/images/misc/technicians-testing-a-heat-pump-reversing-valve-so.webp) ### Why Mid-Rise Boards in York Region Pick Us - Service contract Ops Manager James Kowalski - Downtown Markham 24-unit heat pump repair experience - Trane Axiom and ClimateMaster parts on the truck - Annual contracts from $185 per unit - Magic-Pak replacement with TSSA gas sign-off - Written scope and price before work Why This Area Is Different ## Why Markham Condos Benefit from Service Contracts Markham's condo stock is mostly 2000s and 2010s heat pump mid-rises. These buildings are past their first years but not yet at replacement age, which is exactly when regular service saves the most money. Most of the expensive failures we see here started as a cheap part nobody checked. Trane Axiom, ClimateMaster and Magic-Pak equipment covers most of what we see. A crew that works these every week diagnoses faster and carries the right parts. Equipment we service most here - Trane Axiom - ClimateMaster - Magic-Pak - McQuay Response: 24-hour emergency, same-day diagnostic Building Stock ## Condo Building Stock by Decade The decade a building went up tells us a lot about its equipment before we arrive. Here is what we typically find locally. 1980s Thornhill-Markham towers with hydronic fan coils, original valves and scaled coils. 1990s Milliken mid-rises with Magic-Pak units and early heat pumps nearing end of life. 2000s Unionville mid-rises with water-source heat pumps due for hoses, strainers and valves. 2010s+ Downtown Markham towers with Trane water-loop heat pumps and newer controls. 24-Hour Dispatch ## After-Hours Condo HVAC Emergencies Emergency dispatch runs 24 hours, 7 days. After-hours diagnostics are $285. Call (647) 294-5454 [tel:+16472945454 →](tel:+16472945454) . ### Heat pump hose leak Close the isolation valves if you can and call (647) 294-5454.

Straight Answers ## Markham Condo HVAC Questions Answered Do service contract buildings get faster response? Emergencies get same-day response, often within a few hours around Unionville and Cornell via Highway 7 and Highway 407. Contract clients get priority booking, and routine diagnostics are normally scheduled within one business day. Which Markham areas do you serve? Downtown Markham, Unionville, Markham Centre, Cornell, Milliken, Cathedraltown and Thornhill east of Yonge. Heat pump towers near Highway 7 and Magic-Pak low-rises in Milliken are our most common calls. How much is an annual service contract? One visit per unit per year runs $185 to $240, and two visits per year $320 to $420, depending on equipment and building size. Each visit includes filter, pan, strainer, electrical and refrigerant checks, with a report per suite. My heat pump is stuck in heating mode in May. What is wrong? Usually the reversing valve is not shifting. It may be the thermostat signal, a failed solenoid coil, which is a quick fix, or a stuck valve that needs replacing. A $240 heat pump diagnostic finds out which. Do you work on Trane Axiom heat pumps? Yes. Trane Axiom water-loop heat pumps are common in Downtown Markham and Markham Centre towers, and we carry their common contactors, capacitors and solenoid coils on the truck. Our tower went up after 2005. Is it too early for heat pump trouble? Not really. Downtown Markham construction began in 2005, so its first towers now have water-loop heat pumps 15 to 20 years old. That is when reversing valves, contactors and coaxial coils start failing, especially where annual maintenance was skipped. A service contract catches most of it at the spring and fall visits.
