Questions and Answers

What should I consider when thinking about an oil-to-gas conversion for my Portland home?

Converting from oil to gas is a significant upgrade that can increase efficiency and reduce long-term fuel costs, which is particularly valuable with our Northwest winters. At Morrison Contracting, we start by evaluating your current system, home layout, and local gas line availability. We'll provide a clear assessment of the upfront investment versus the projected savings on your utility bills. Our honest approach means we'll only recommend it if it truly suits your home and budget, and we handle the entire process—from securing permits to installing your new high-efficiency gas furnace—with precision.

My new HVAC system isn't performing as expected. Could my old ductwork be the issue?

Absolutely. Even the most efficient new furnace or air conditioner can be hampered by outdated, leaky, or improperly sized ductwork. This is a common issue we address in older Portland homes. We specialize in evaluating and upgrading existing duct systems to maximize airflow and efficiency. By sealing leaks, resizing sections, or adding new returns, we ensure your new equipment operates as intended, improving comfort and reducing energy waste. It's a crucial step that protects your investment.

My smart thermostat keeps losing connection, and my outdoor AC unit looks dirty. What's going on?

These are two very common issues for Portland homeowners. Our wet springs and dusty summers lead to debris and moss quickly clogging condenser coils, reducing efficiency and causing strain. We include a thorough coil cleaning in our seasonal maintenance to prevent this. Smart thermostat connectivity problems often stem from Wi-Fi signal issues, outdated firmware, or compatibility glitches with your HVAC system. During a service call, we'll diagnose both the thermostat setup and your equipment to restore reliable, automated control of your home's climate.
