TEMPSTAR FURNACE & AC REPAIR

Newer Tempstar cold-climate models are built to operate efficiently even in freezing temperatures, with backup heat options for extra support. They offer high-efficiency electric cooling and heating and enhanced summer dehumidification. The great thing is that all of their models are quiet!

This can happen during extreme cold or if the unit is undersized. A system inspection can confirm whether recalibration or upgrading is needed.

Most last 12 to 15 years, but regular maintenance and filter changes can extend that life.

Yes! Heat pumps can often replace older AC systems, offering both cooling in summer and heat in spring/fall.

Not always. Ductless Tempstar models are available for homes without existing ducts.

Yes, many models are engineered for low-temperature operation and include built-in defrost controls.

Depending on the model, up to five zones can be connected for customized comfort in different rooms.

Clean filters every few weeks and have a professional inspection once a year to keep airflow strong and energy use low.

Not at all! Most Tempstar ductless units and systems are whisper-quiet which is perfect for bedrooms or offices.

Yes! Tempstar ductless systems can significantly reduce heating costs, especially when used to heat only occupied spaces instead of the entire home. They work on a zoned heating principle, meaning each indoor unit operates independently. This lets you warm specific rooms, like bedrooms or living areas, without wasting energy on unused spaces. Plus, because ductless systems don’t lose heat through ductwork (which can account for up to 30% of energy loss in traditional systems), they deliver more of the heat you’re paying for directly into your living space.

If your Tempstar thermostat keeps rebooting or losing settings, it’s usually due to power supply issues such as weak batteries, a tripped breaker, or a loose connection at the control board.

Some Tempstar smart thermostats, like the Ion™ System Control, draw low-voltage power from your HVAC system; if that line is unstable, the thermostat will restart automatically. A professional can check the C-wire voltage, ensure the transformer is delivering steady power, and rule out firmware or control board faults that aren’t visible to homeowners.

For Tempstar smart thermostats such as the Ion™ System Control or Observer® Communicating Thermostat, start by selecting Menu > Wi-Fi Setup on the screen.

From there, choose your home network and enter your password. Once connected, download the Tempstar Ion System Control app or Observer App to your smartphone to manage settings remotely.

If your thermostat fails to connect, our technicians can help update firmware, boost your router’s range, or troubleshoot interference from metal ductwork, common in Calgary basements.

DIY installation isn’t recommended. Tempstar’s communicating thermostats use a four-wire communication protocol that links directly to compatible Tempstar furnaces, ACs, or heat pumps.

Incorrect wiring can cause short circuits or disable your system’s variable-speed functionality. Our licensed Calgary technicians guarantee proper connections, software pairing, and control calibration.

Tempstar smart thermostats use adaptive algorithms that monitor both indoor conditions and outdoor temperature swings. In Calgary, where mornings can be frosty and afternoons mild, the thermostat automatically adjusts furnace or AC output to maintain comfort while avoiding energy spikes. Paired with a Tempstar variable-speed system, it can ramp heating or cooling gradually, saving up to 10 to 15% on energy during seasonal transitions.

In most cases, yes. Many Tempstar thermostats, especially non-communicating models, are backward-compatible with older single-stage or two-stage HVAC equipment.

However, to take full advantage of features like humidity control, zoning, or Wi-Fi scheduling, a technician can confirm your furnace or AC control board supports these functions. We can also upgrade your thermostat wiring if your system lacks a common wire (C-wire), which is needed for newer smart models.

For the Tempstar DGAPA Air Purifier, the pleated MERV 15 filter should typically be replaced once a year, though Calgary’s dry, dusty conditions or wildfire smoke may require a filter change every 6 to 9 months. The filter plays a key role in the system’s three-step charge, capture, and kill process, attracting and neutralizing dust, pollen, bacteria, and viruses. Replacing it on schedule keeps airflow strong and makes sure the electric field continues inactivating up to 99% of airborne microbes.

If you own the UVCAP Carbon Air Purifier with UV, plan to replace the carbon core every 12 months and the UV bulb every 24 months for consistent odour and microorganism reduction.

A musty or stale smell can appear when the purifier’s carbon core or MERV 15 filter becomes saturated with trapped particles or moisture. In Calgary, fluctuating humidity or poor ventilation can allow condensation to form around the air handler, leading to mild microbial growth on the filter surface.

For DGAPA models, replacing the filter usually removes the odour; for UVCAP systems, verify that the UV bulb is still active, as UV light helps prevent mould or bacteria buildup on the evaporator coil. If the smell persists, a technician can inspect for excess coil moisture or airflow restrictions.

Yes! Both the DGAPA Air Purifier and UVCAP Carbon Air Purifier with UV are designed for in-duct installation. They’re compatible with almost any brand of ducted HVAC system, whether you use a Tempstar furnace, air handler, or another manufacturer. The purifier mounts near the return air duct or evaporator coil, where it treats all circulated air in your home.

When professionally installed, it adds minimal airflow resistance, maintaining system efficiency while purifying your entire indoor environment.

While air purifiers don’t add humidity, they play a vital role in improving indoor comfort and health, especially in Calgary’s dry climate. The DGAPA purifier captures and deactivates airborne dust and allergens that become more irritating in low humidity, while the UVCAP Carbon model reduces odours, gases, and microorganisms on the coil.

For complete comfort, many homeowners pair their purifier with a Tempstar whole-home humidifier, balancing moisture and cleanliness for healthier breathing year-round.

Yes. Proper installation guarantees your purifier is positioned correctly within the return-air duct and wired safely to your HVAC system. For DGAPA units, this setup is essential to make sure the electric charge and airflow work in harmony.

For UVCAP models, the UV lamp and carbon core must be installed at the right distance from the evaporator coil for effective germicidal action.

Our licensed Calgary HVAC technicians handle installation, calibration, and ongoing maintenance to protect your warranty and guarantee long-term performance.

Reset furnace power; if it reoccurs, a technician should inspect ignition and gas systems.

Check for vent blockages or water in tubing.

Clear snow or debris from outdoor vent.

Replace dirty filter and ensure vents are open.

Likely gas valve or flame sensor issue, requires professional service.

System resets after 3 hours; make sure airflow is clear.

Remove obstructions or ice buildup from vent.

Electrical issue: contact technician to correct line/neutral wiring.

Normal operation, no action needed.

Check thermostat settings and breakers.

Check air filters and coil for dirt. If persistent, check refrigerant levels.

Likely due to refrigerant pressure limits. Check for leaks or blocked airflow.
