One of the hardest things about home services is knowing whether the company at your door is being honest about what you need. Heat pumps are no different. So here's the simple framework we share with our own friends and family.

There are roughly two kinds of work that gets done on a ductless heat pump: cleaning and repair. They look similar from the outside but they fix very different things.

What cleaning actually fixes

Cleaning fixes problems that come from buildup. That means:

  • Weaker airflow than the unit used to have
  • Musty, stale, or "damp basement" smells
  • Visible dust or grime on filters, louvres, vanes, or the inside of the unit
  • A slight loss in cooling or heating performance over months/years
  • The unit running longer than it used to for the same comfort level

If your heat pump still turns on, still heats, still cools, but feels "off," cleaning is almost always the right first step. It's also the cheapest one.

What cleaning does not fix

Cleaning will not fix anything that's actually broken. If you see any of these, you need a licensed HVAC technician, not us:

  • The unit won't turn on at all
  • It blows ambient-temperature air — no heat, no cold — even at full settings
  • The outdoor unit is making grinding, clunking, or hissing noises
  • There's a refrigerant smell (sweet, slightly chemical) near the unit
  • Visible ice on the indoor unit during normal operation
  • An error code on the remote that doesn't clear after a reset
  • Water dripping onto the floor from the indoor unit

Don't let anyone — including us — sell you cleaning to fix any of those. They're symptoms of something a cleaning won't touch.

The grey areas

A few situations are honestly hard to call without seeing the unit:

  • "It's not as cold as it used to be." This could be a dirty coil (cleaning helps) or low refrigerant (it doesn't). A proper cleaning often reveals which.
  • The defrost cycle runs more than it used to. Usually a clean coil helps. Sometimes it's a sensor.
  • The fan sounds different. A dirty blower wheel makes a heavier, rumbling sound. A failing motor makes a thinner, grinding one. Different problems, different fixes.

If you're in a grey area, ask the company you call whether they're a cleaning company or a repair company. The honest ones will tell you which they are, which they aren't, and what they think you need.

What we do, and what we don't

We clean. We don't upsell repairs. BlueBear is a cleaning company. If we see something during a visit that looks like a repair issue, we'll tell you what we saw, write it down for you, and suggest a couple of licensed HVAC partners we trust. We don't get a referral fee. We just don't want to be the company that pretends a $200 cleaning will fix a $1,500 problem.

Five questions to ask any company at your door

These are the questions we wish more customers asked us:

  1. "Are you licensed for refrigerant work?" If they hesitate, they're not — and that's fine for cleaning, but not for repair.
  2. "What exactly did you find, and can I see it?" Honest companies show you. Photos, the dirty cloth, the inside of the unit. If they don't offer, ask.
  3. "What happens if I do nothing?" A real answer ("the smell stays" or "the unit will keep cycling longer") is more useful than a scary one.
  4. "What's the cheapest version of fixing this?" If they only have an expensive option, that's information.
  5. "Can I get a written quote before you start work?" Always yes from anyone reputable.

You don't have to be rude to ask these. Any company worth hiring will appreciate that you're paying attention.
