Looking for advice on a heat pump issue because we’re getting nowhere with the installer.

We have a slab home in Central British Columbia, Canada, with the main living space on the upper floor. The house is around 2700 sqft and built in 2007 with original everything.
In Nov 2025 we replaced our old furnace + AC with a new heat pump/furnace combo system.

Right away it felt like the heat pump struggled to properly heat the house in colder weather, so I adjusted the thermostat settings to have the furnace kick in whenever it’s 5°C (41°F)or below.

Then when we first started trying to cool the house this spring, the heat pump would not cool properly if our Google Nest thermostat was set to the “Heat/Cool” auto mode. We had to manually switch it to either Heat only or Cool only to get it to work at all.

Now that warmer weather has arrived, the main house cannot get below 24°C (75°F)during the day if it’s above about 26°C (79°F)outside. The thermostat is set to 21°C (70°F), but the indoor temperature slowly climbs all afternoon and only starts cooling after the sun goes down.

Our previous AC system did not seem to have this problem.

The HVAC company has been back three times now, and each visit the tech was here for more than 6 hours. They originally blamed the Google Nest thermostat and insisted we replace it with an Ecobee, which we did and it cost over $300, but it has not seemed to made difference other than we can run it in heat/cool mode.

At this point I’m trying to figure out:

• Does this sound like an undersized heat pump?
• Could this be an airflow or installation issue?
• Is there a common setup/configuration issue with heat pump + furnace combo systems that could cause this?
• Is it normal for a newer heat pump system to cool noticeably worse than an older AC unit?

Any ideas on what I should be asking the HVAC company to specifically check?

A few months back, I made a post about applying for a promotion that I didn't get. I had a lot of people reach out in the org and say that they thought I should have been the chosen candidate, I was embarrassed.

It was a direct move up and I felt slighted but also a failure. One poster noted that I likely bombed the interview and on reflecting I didn't disagree.

Fast forward a month and a bit and the person that was hired into the role, my new manager, is let go.

A few weeks pass and the hiring manager reaches out to me and offers me the promotion.

I am trying to look at it that I wasn't the second choice but the correct first choice and now have to demonstrate that. But still feel a way about it that I am trying to get over.

How would you handle the situation?
