How to Prepare Your Home for Extreme Temperatures Before Summer Hits
Most homeowners think about their HVAC system twice a year — when it stops working, and when the bill arrives. That's the wrong order. A little preparation in spring keeps your home comfortable through the heat and avoids the kind of repair bills that ruin a July weekend.
If you're in the Pacific Northwest, quality heating and cooling in Beaverton matters more than people expect. Summers here have been getting hotter, and homes built before 2000 often weren't designed for extended heat events. Whether you're weighing a new AC installation or just trying to squeeze more life out of your existing system, the prep steps are largely the same — and most of them cost nothing.
Change the Filter First
This sounds obvious. It isn't obvious enough — roughly 40% of HVAC service calls involve restricted airflow from a clogged filter, and most are entirely avoidable.
A dirty filter doesn't just reduce air quality. It forces your system to work harder, which raises energy consumption and accelerates wear on the blower motor. A standard 1-inch filter should be swapped every 30–60 days during high-use seasons. Thicker 4-inch media filters can go 6–12 months, but they still need checking.
Pull the filter out and hold it up to light. If you can't see through it, replace it today. That's the whole step.
Insulation Does More Work Than You Think
Insulation is the part of home comfort nobody wants to think about because it lives in the attic. But a poorly insulated attic can add 20–30% to your cooling load on a hot day — meaning your system runs longer, consumes more energy, and reaches the end of its service life faster.
In most Pacific Northwest climates, attic insulation should sit at R-38 to R-60. If yours is thin, compressed, or patchy, that's your first fix before touching the thermostat or the equipment. Sealing air leaks around recessed lights, attic hatches, and duct penetrations matters just as much as the insulation depth itself.
Cold air escapes through gaps. Hot air always finds them.
Thermostat Settings That Actually Save Money
A programmable thermostat doesn't save money automatically — it saves money when set up correctly. Most households benefit from a few specific habits:
Set the daytime cooling point to 78°F when home, 85°F when away
Use fan-only mode in the evening to pull in cooler outside air before temperatures peak
Avoid dramatic setpoint swings — dropping from 85°F to 68°F doesn't cool the house faster, it just runs the system longer than necessary
Smart thermostats like the Ecobee or Nest learn your schedule over time and adjust automatically. At $150–$250, they're worth it if you plan to stay in the home for more than a couple of years. The payback period on energy savings alone is usually under 24 months.
Signs Your System Needs More Than a Tune-Up
Some systems need more than seasonal maintenance. Watch for these before summer arrives:
Uneven temperatures between rooms — one floor noticeably hotter than another
Frequent short cycling: the unit kicks on and off every few minutes
Unusual sounds at startup — grinding, squealing, or banging
Visible ice forming on the refrigerant lines or indoor coil
Energy bills climbing without any change in how you use the system
Any one of these is worth investigating. Two or more together, and you're likely looking at a repair — or a replacement conversation. Pushing an aging unit through another summer usually costs more in the long run than addressing the problem in May.
What Conrad Heating and Cooling Handles Differently
Professional assessment changes the calculus entirely. Conrad Heating and Cooling has been serving the Beaverton area for years, and the difference between a contractor worth calling and one that isn't comes down to diagnostics. They measure static pressure, verify refrigerant charge, inspect electrical connections, and confirm airflow against the system's rated specs. No guessing.
A seasonal inspection from Conrad typically takes 60–90 minutes and covers everything the manufacturer recommends for summer readiness. If something's off, you get a clear explanation — not a list of upsells you didn't ask for.
Is It Time to Replace the System?
If your current unit is more than 15 years old, still runs on R-22 refrigerant (phased out since 2020), or has needed two or more major repairs in the past three years — the math usually favors replacement over another patch job.
Conrad Heating and Cooling handles the full process: load calculation using Manual J methodology, proper equipment sizing, duct inspection, and installation. Do it before the heat arrives, and you skip the worst part of summer HVAC work — waiting three weeks for an appointment slot because everyone else's system failed at the same time as yours.
