Uneven Heating Around the House

Some rooms toasty, others chilly? You might have airflow issues, leaking ducts, or a blower motor that’s wearing out.

Strange Noises or Burning Smells

A dusty smell is fine for the first minute, but grinding, banging, or smoke-like odors mean something’s wrong.
Scheduling a tune-up before the temperatures drop helps prevent major repairs later.

Rising Energy Bills Without a Clear Reason

If your PG&E bill is climbing but your usage hasn’t changed, your system might be losing efficiency. Dirty filters, aging motors, or poor airflow make your heater work harder than it should.

Stay ahead of it by joining our Energy Savings Agreement (ESA), which covers regular maintenance and priority scheduling.

Weak Airflow or Slow Startup

If it takes forever for warm air to start or the airflow feels weak, it’s time for a checkup. Clogged filters or worn blower motors are common, but if you’re calling for repairs often, it may be smarter to plan a replacement.

Your Heater Is Over 12 Years Old

Most heating systems last about 12 to 15 years. Past that point, you start paying more in repairs and energy than it’s worth.

What to Expect When You Call Nalk

We start by sending a technician to your home for a full system assessment. We look at your current equipment, your comfort goals, and your home’s layout to make the best recommendation. Sometimes, that visit reveals something small we can fix right away to make your existing system run better. It’s all part of our fix-it-first philosophy — we’ll never push a replacement unless it makes real sense.

There is a charge for this visit, but we keep it affordable because we don’t want cost to be a barrier to smarter energy use and better comfort.

If a heat pump is the right fit, we’ll walk you through your options and schedule the install at a time that works for you.
