    Fast and Fair Price. I contacted them in the evening and they quoted a fair price. The next morning they have my AC moved to a different location and everything went well. I will definitely recommend these guys for any HVAC works.

    Common AC Repair Issues

    We have extensive experience in handling a wide range of AC repairs for various makes and models. If your AC unit experiences any of these issues then call one of our dedicated team to schedule an appointment with one of our technicians.

    AC unit won’t turn on: This could be an issue with the circuit breaker or the capacitor, if one of these is faulty or dead then it might need to be replaced. Another explanation could be that the air filters are clogged causing the unit to shut off to prevent damage.

    Unit is making unusual noises: Over time, the fan belt might have come loose or been malfunctioning, this could cause rattling or banging noises. If your unit is making a hissing sound then this could be caused by a refrigerant leak, dirty evaporator coils, or blocked air ducts.

    Blowing warm air: This could be because your unit is working less efficiently because of clogged air ducts, refrigerant leaks, or dirty condenser coils. It could also be because of faulty parts, such as the compressor or thermostat.

At One Stop HVAC, we provide comprehensive AC servicing in Calgary to help you extend the lifespan of your air conditioner. Our team of expert technicians will thoroughly inspect your unit, clean the filters, adjust coolant levels, and ensure proper lubrication of all moving parts.

    Investing in a new AC unit can provide you with a more reliable system that offers enhanced efficiency. However, it’s essential to determine the right timing for replacement to avoid premature action. While repairs are generally more cost-effective in the short term, continuously paying to sustain an underperforming system could prove less economical in the long run.

    If your AC unit is blowing warm air, there could be several factors contributing to its decreased efficiency. Clogged air ducts, refrigerant leaks, or dirty condenser coils may impede proper cooling. Additionally, faulty components like the compressor or thermostat could be the culprit. If the problem persists, please don’t hesitate to call one of our team members for advice or schedule a home visit.

    If you’re hearing unusual noises from your AC unit, there could be a few potential causes. Over time, the fan belt may become loose or start malfunctioning, resulting in rattling or banging noises. Additionally, a hissing sound could indicate a refrigerant leak, dirty evaporator coils, or blocked air ducts. If you notice any of these issues, it’s best to consult our experts at One Stop HVAC for a thorough inspection and professional assistance.

    For peak performance and to avoid significant breakdowns, it is advisable to have your AC unit professionally serviced at least once per year. This routine maintenance helps maintain optimal functionality and keeps your AC running smoothly throughout the year. Trust One Stop HVAC to provide the necessary servicing to keep your AC unit running effectively.

    The frequency of AC filter replacements can vary depending on the type of filters used in your home. If you utilize standard 1 to 3-inch air filters and don’t have allergies, it is recommended to change the filters every 30 to 60 days. However, if you experience mild to moderate allergies, it is advisable to replace or change the filters more frequently, approximately every three weeks to maintain optimal indoor air quality.
