A homeowner in Clarkson called us in January after their heat pump stopped producing heat overnight. By the time we arrived the next morning, the indoor temperature had dropped significantly. We diagnosed a failed reversing valve, which is one of the more common failure points on heat pumps that have been in service for several years. We had the part on the truck, completed the repair the same morning, and the system was back to full heating capacity before noon. That kind of situation is exactly why we stock common parts and prioritize repair calls. When your heating system fails in winter, speed and accuracy matter.
Heat pumps are reliable systems, but like any mechanical equipment they develop issues over time. Catching problems early usually means a simpler, less expensive repair. Ignoring warning signs often leads to more significant damage.
If you notice any of the following, call us for a diagnostic visit. We identify the root cause and give you a firm quote before any work begins.

Most heat pump failures fall into a small number of categories. Our technicians are trained to diagnose and repair all of them.
Low refrigerant due to a leak reduces both heating and cooling capacity. A failed reversing valve causes the system to get stuck in one mode. Both are common repairs we handle regularly and can often complete in a single visit.
Capacitors, contactors, and control boards are frequent failure points as systems age. These components are often available on our service vehicles, allowing same-day repair in many cases.
A malfunctioning defrost control causes the outdoor unit to ice over in cold weather. Fan motor failures affect both airflow and efficiency. We carry common fan motors and defrost components to minimize wait times.
We arrive within the scheduled window, perform a thorough diagnostic of the system, and identify the root cause of the problem. We do not guess or replace parts speculatively.
Before any repair work begins, we explain what is wrong, what needs to be done, and provide a firm quote. You decide whether to proceed. No pressure, no surprises.
We carry common parts on our service vehicles and complete most repairs in a single visit. If a part needs to be ordered, we give you a clear timeline and follow up promptly.
After the repair, we run the system through a full cycle to confirm it is operating correctly. We walk you through what was done and advise on any preventive measures to avoid future issues.

If your repair turns out to be more significant than expected, or if the diagnostic reveals that replacement is the more practical option, we offer flexible financing so you can move forward without the financial pressure.
We offer flexible financing through trusted lenders, including 0% interest for 12 months with approved credit. Monthly payment plans are available to fit any budget.
We diagnose the problem, explain what needs to be done, and give you a firm quote before any repair work begins. No surprise charges.
We identify the root cause, not just the symptom. A proper diagnosis means the repair holds and you are not calling us back for the same issue two weeks later.
All repair work is backed by our labour warranty. If the repair fails due to our workmanship, we come back and make it right at no additional cost.

Common signs include the system not heating or cooling effectively, unusual noises such as grinding or rattling, the outdoor unit icing up heavily and not defrosting, the system short-cycling on and off, or a significant increase in energy bills without a change in usage.
We aim to respond to repair calls within 24 hours. For urgent situations where the system has failed completely, we prioritize scheduling as quickly as possible. Call us directly at (437) 837-0777 for urgent repair requests.
The most common repairs we handle include refrigerant leaks and recharging, reversing valve failures (which cause the system to get stuck in heating or cooling mode), defrost control issues, capacitor and contactor replacements, fan motor failures, and electrical connection problems.
It depends on the age of the system, the cost of the repair, and the overall condition of the equipment. As a general guideline, if the repair cost exceeds 50% of the cost of a new system and the unit is more than 10 years old, replacement may be the better long-term investment. We give you an honest assessment and let you decide.
