Frequently Asked Questions

I have gas heat now. Is switching to a heat pump a good idea for Ottawa winters?

Modern cold-climate heat pumps are engineered to operate efficiently in Ottawa's winter lows, making them a viable primary heat source. The decision involves analyzing your gas versus electricity costs during the winter months. Since ComEd's peak hours are 14:00 to 19:00, a well-insulated home with a properly sized heat pump could avoid peak pricing for heating. The switch can significantly reduce your fossil fuel consumption, and when paired with the available federal rebates, the payback period is often attractive for homeowners seeking to decarbonize.

What does the new 13.8 SEER2 minimum efficiency standard mean for my Ottawa home?

The SEER2 rating, mandated in 2023, is a stricter real-world measure of cooling efficiency. For Ottawa homes, a new system meeting this standard will use significantly less electricity than older units. With ComEd rates averaging $0.14 per kWh, the operational savings are tangible. These savings combine with the active Inflation Reduction Act rebates, which can provide up to $8,000, making a high-efficiency upgrade a sound financial decision that lowers your carbon footprint and utility bills.

My Ottawa AC unit is original to my 1957 home. Is it time for a replacement?

Yes, a system from 1957 is approximately 69 years old, far exceeding its design lifespan. In Ottawa's humid continental climate, older galvanized steel ductwork and refrigerant lines are prone to developing leaks and corrosion. This age directly contributes to the common failure point of condensate line freezing or clogging, as the entire system operates inefficiently and struggles to manage latent heat removal. Continuing to repair such an aged system often becomes cost-prohibitive compared to a modern, efficient replacement.

Why does my AC struggle when it hits the mid-90s, even though it's rated for 89°F?

Air conditioners are designed to maintain comfort up to a specific outdoor temperature, known as the design temp. Ottawa's design temp is 89°F. When actual temperatures exceed this, as they often do during summer peaks, the system must run continuously and loses its ability to maintain the desired indoor delta T. Modern systems using R-454B refrigerant maintain better capacity and efficiency at these higher temperatures compared to older R-22 or R-410A units, but some capacity loss is inherent in the physics of the refrigeration cycle during extreme heat.

What are the permit and code requirements for a new AC installation in Ottawa now?

All HVAC replacements in Ottawa require a permit from the City of Ottawa Building and Zoning Department. As of 2026, installations involving new A2L refrigerants like R-454B must adhere to updated safety codes. These standards mandate specific leak detection systems, airflow requirements for equipment rooms, and revised refrigerant charge limits due to A2Ls' mild flammability. Using a licensed contractor ensures compliance with these local ordinances and the latest EPA Section 608 regulations, protecting your home investment and maintaining valid manufacturer warranties.

My Ecobee thermostat is showing an 'E1' alert. What does this mean for my Ottawa HVAC system?

An Ecobee E1 error code signals that the thermostat has lost communication with your HVAC equipment. In Ottawa, this often points to a system shutdown caused by a primary safety limit, such as a clogged condensate line triggering a float switch or a high-pressure cut-out due to a dirty condenser coil. It's a diagnostic alert that prevents the system from restarting automatically, protecting the compressor from damage. A technician should investigate the root cause—frequently related to our humid climate and seasonal debris—before resetting the system.

My AC just quit on a hot day in Downtown Ottawa. How fast can a technician get here?

For a no-cool emergency, our dispatch prioritizes calls from the Downtown area. From our service center near Washington Square Park, we can typically reach any home in your neighborhood within 5 to 10 minutes via I-80. This rapid response is critical to prevent further heat gain and potential secondary issues like ice formation on the evaporator coil. We'll diagnose the immediate cause, whether it's a tripped breaker, a failed capacitor, or a clogged condensate line.

With Ottawa's ozone risk and May pollen peak, can my old ducts handle better air filters?

Upgrading filtration is wise for mitigating ozone precursors and seasonal allergens. However, the static pressure capabilities of your existing galvanized steel ductwork are a primary concern. While durable, these older systems were not designed for high-MERV filters. Installing a MERV-13 filter without a professional static pressure test can severely restrict airflow, reducing cooling capacity and potentially damaging the blower motor. A technician can assess your duct system and may recommend a bypass filter cabinet or a standalone air purifier as a safer alternative.
