Fast response from certified HVAC professionalsAir Conditioning for the Pacific Northwest
The Puget Sound region's summers have become increasingly warm, with multi-day heat events that push indoor temperatures to uncomfortable and even dangerous levels. Many homes in King, Pierce, Kitsap, and Thurston counties were built without air conditioning, relying on the historically mild Pacific Northwest climate. QC Mechanical helps homeowners add cooling capability — whether through central air, a ductless mini-split, or a heat pump that provides both cooling and heating.
Proper system sizing is critical for effective, efficient cooling. An oversized AC system will cool the air quickly but short-cycle, failing to adequately remove humidity and wearing out components prematurely. QC Mechanical performs Manual J load calculations on every air conditioning installation to determine the exact cooling capacity your home requires.
- Central AC systems that connect to existing ductwork
- Ductless mini-split cooling for homes without ducts
- Heat pump systems that provide both cooling and heating
- Manual J load calculations for proper sizing on every installation
- High-efficiency models that minimize energy costs
- Quiet operation for peaceful indoor comfort
Types of Cooling Systems We Install
QC Mechanical installs the full range of residential cooling equipment to match your home's needs and existing infrastructure. Central air conditioning systems are the best fit for homes that already have ductwork from an existing furnace. We install a condensing unit outside and connect it to an evaporator coil and air handler, distributing cool air through your existing duct runs.
Ductless mini-split systems from Mitsubishi are ideal for homes without ductwork, room additions, bonus rooms, or homeowners who want zone-by-zone cooling control. For homeowners who also need heating, a heat pump provides year-round cooling and heating from one system — the most versatile option for the Pacific Northwest climate.
- American Standard and RunTru by Trane central air conditioners
- Mitsubishi ductless mini-split cooling systems
- Multi-zone ductless systems for whole-home cooling without ducts
- Heat pump systems for combined heating and cooling
- Variable-speed and inverter-driven compressors for maximum efficiency
