Reliable, Fast HVAC System Repairs
Our HVAC company provides fast services that restore indoor comfort. If your cooling system emits an odor similar to acetone or nail polish remover, it’s important to call us right away. These smells might mean your AC has a refrigerant leak. You might also notice a hissing noise coming from the unit. In this scenario, we’ll need to check the refrigerant lines and compressor. If we find any leaks, we’ll repair them promptly to prevent further damage. Other common AC repairs that we help with include dirty evaporator coils and clogged condensate drains.
If the heater ever makes a crackling noise, this could mean there’s a cracked heat exchanger. Banging and rattling sounds are additional clues. A cracked heat exchanger greatly impacts the performance of the heater by preventing proper heat transfer. It can also result in carbon monoxide leaks, which can cause catastrophic air poisoning. We’ll inspect the heat exchanger and venting system to determine whether to repair or replace the affected components. We also offer repairs for faulty ignition systems, broken blower motors, and damaged gas valves. Whatever the issue, we can diagnose and fix it fast.

Heating and Cooling Company: Expert Installations
Using our vast knowledge as an industry-leading heating and cooling company, we can help you determine whether a ducted or ductless HVAC configuration will work best in your house. Homes that don’t have any existing ductwork often choose ductless versions because of the easy setup. Going ductless can also help save money because you won’t have to install or maintain ductwork.
Your home’s insulation, square footage, and layout greatly impact choosing the best setup. To achieve optimal heating and cooling efficiency, we might recommend choosing a system with a variable-speed blower motor. A system like this one adapts its output to match the specific temperature settings you want for your home. Using this type reduces energy costs while also extending the life of the equipment. However, we won’t use pushy sales tactics and will work with you to find the best options in your budget range.

Maple Valley’s HVAC Contractor for Maintenance
For most homes, a yearly tune-up will keep the HVAC equipment performing efficiently and reliably year-round. However, for homes with high humidity levels, more frequent tune-ups might be necessary. Excess moisture affects heating and cooling systems by corroding metal components and promoting mold growth. We will clean and disinfect the coils and inspect the drain line for clogs during maintenance to prevent moisture-related problems. Other key parts of a maintenance visit include lubricating moving parts and checking refrigerant levels for proper charge.
