 Trustindex verifies that the original source of the review is Google. We highly recommend Altitude Heating & Cooling for HVAC systems.
Justuce and Dylan replaced our 26 year old, 2 HVAC systems in March, 2026 .
It was a wonderful experience that we had with them. They were dedicated, attention to details and especially, they care for their customers.

Here’s an example.
We had a clothes dryer vent that directly blew out to heat pumps and had to clean up occasionally for years. They bought a vent and flex hose for the new location and its perfect location. They didn’t charge for the materials and labor, and it was a surprise gift for us.

It was an example of how they care about their customers and take pride in their work.
The HVAC systems are expensive. They gave us 3 options to work within our budget to find the right fit for us.
I hope this review helps you decide to hire this company to install your house systems. We’re lucky to have Justuce and Dylan.
Nice work Gentlemen!

Frequently Asked Questions

Why is my heat pump struggling in the Snohomish County climate?

What are signs I need heat pump repair in Lake Stevens or Snohomish?

Signs include poor heating or cooling, ice buildup, strange noises, short cycling, higher energy bills, weak airflow, or a system that will not turn on. Homeowners in Lake Stevens, Snohomish, and nearby areas should schedule heat pump repair when these issues appear.

Can heavy PNW moisture affect my heat pump?

Heat pump repair questions

Why is my heat pump blowing cold air?

A few minutes of cool air with steam from the outdoor unit is normal defrost. If cold air lasts more than about 15 minutes, check that the thermostat is set to Heat and the filter is clean. If it continues, a defrost control, reversing valve, refrigerant or backup heat problem needs repair.

Is steam from my heat pump normal?

Yes. Steam from the outdoor unit during defrost is normal. Smoke or a burning smell is not, so turn the system off and call.

What does a reversing valve do?

It switches the heat pump between heating and cooling. When it sticks, the system can run without ever heating the house.

Can a frozen heat pump be damaged?

Yes. A heat pump that stays iced over can strain the compressor. Turn it to emergency heat and call for repair. Never chip ice off the coil.
