I highly recommend this honest business! Our hallway control panel went completely dark, and the repairman quickly found a loose wire behind the drywall, restoring our heat in minutes.

That $15k–30k replacement might be a $500 fix.
A lot of “bad furnaces” and “dead ACs” are really airflow, a clogged drain, a dirty coil or one failed part. We check the whole system before anyone says “replace.”

How it works
Start step 1 Fix your comfort. Don't guess it.
01We diagnose
A specialist checks the entire system (airflow, ductwork, performance) to find the real problem, not just the symptom.
02You get real options
Repair if it makes sense, replace if it doesn’t. Every option priced in writing. No pressure.
03We fix it right
Repairs are often same-day; installs typically within 1–2 days. Clean, to code, built to last.
What neighbors say
Neighbors, in their words.
My central air completely froze over with ice during a humid weekend, but the tech from Sub Zero came out fast to thaw and fix the refrigerant leak. Everything is running perfectly now, and the house is finally comfortable again!

Our air stopped working completely and we panicked. The repair guy came over quickly and figured out the wall thermostat just needed new batteries. He swapped them out, checked the rest of the system to be safe, and didn't overcharge us. Very honest and simple service. Highly recommend!

Do you offer second opinions?
Yes, free. If someone told you the whole system has to go, we check it and tell you straight whether that is actually true.
Should I repair or replace my system?
It depends on age, condition and the cost of the fix. Newer system and a minor part? Repair it. Older and failing repeatedly? We price both, in writing, so you can choose.
How fast can I get a new system installed?
Most systems are installed within 1–2 days after your estimate, depending on equipment and availability.
Why is one room always hot or cold?
Usually airflow or ductwork, not the equipment. We find the root cause and balance it so the whole house is comfortable.
How often should I service my system?
At least once a year, ideally before heating or cooling season. It prevents breakdowns and keeps efficiency up.
