Donbass Heating & Air Conditioning - Gresham's Reliable HVAC Services

Mini-split systems are an excellent, energy-efficient choice for our climate, offering targeted heating and cooling without extensive ductwork. Since 1997, we've specialized in installing Fujitsu mini-splits, which provide reliable temperature control during both our damp winters and warm summers. They can be a great solution for room additions, older homes without ducts, or improving comfort in specific areas of your house.

Short cycling is a common issue we see in Gresham, often caused by an oversized unit, a dirty air filter, or refrigerant problems. It strains your system and increases energy bills. Our technicians will diagnose the root cause, whether it's a simple maintenance fix or a more complex repair, to restore proper operation and efficiency to your HVAC system.

We recommend professional maintenance at least once a year, ideally before the peak heating or cooling season. For mini-split systems, which we've specialized in for over ten years, this service is crucial. It includes cleaning coils, checking refrigerant levels, and inspecting electrical components to prevent problems, maintain efficiency, and extend the life of your system serving your Portland-area home.
