FAQs
What air-conditioning services do your certified technicians provide in Kelso?
Our local team is trained to handle every stage of an air-conditioning systemâs life cycle. We offer precise load calculations and system sizing for new construction, professional installation of central AC, heat pumps, and ductless mini-splits, rapid diagnostics and repair of all major brands, seasonal tune-ups and safety inspections, indoor-air-quality upgrades such as high-efficiency filters and UV lights, and full system replacements when your existing unit reaches the end of its service life.
How fast can you respond to an AC repair call in the Kelso area?
Because our technicians are dispatched from within Cowlitz County, most customers in Kelso, Lexington, and the Rose Valley area receive same-day service. During peak summer months we prioritize calls based on urgency, but 90 % of no-cool situations are addressed within 24 hours. We also have 24/7 emergency coverage for after-hours breakdowns, weekends, and holidays.
Are your technicians licensed, insured, and certified?
Yes. Every field technician holds a Washington 06A Electrical HVAC/R license, is EPA Section 608 certified for refrigerant handling, and receives factory training from the equipment manufacturers we represent. The company carries full liability and workersâ compensation insurance, so youâre completely protected while we are on your property.
Do you offer maintenance plans for air-conditioning systems?
We offer two tiers of Preventive Maintenance Agreements (PMAs). Both include bi-annual visitsâone in spring for cooling and one in fall for heatingâalong with coil cleaning, refrigerant pressure checks, electrical component testing, and thermostat calibration. Members receive priority scheduling, a 15 % discount on repairs, and documentation that satisfies most manufacturer warranty requirements.
Which brands of air conditioners can you service or install?
Our certified technicians routinely work on Carrier, Lennox, Trane, Rheem, Daikin, Mitsubishi, American Standard, Goodman, and more. We are an authorized dealer for Carrier and Mitsubishi Electric, giving us direct access to OEM parts and extended warranty options, but we are fully equipped to diagnose and repair virtually any residential or light-commercial brand on the market.
What can I do to improve the energy efficiency of my AC system?
Start by replacing or cleaning the return-air filter every 30â60 days during heavy use, keeping outdoor condenser coils free of grass and debris, and setting the thermostat two degrees higher when youâre away. Our technicians can help further by performing an airflow balance, sealing duct leaks, and installing a smart thermostat. If your unit is 12â15 years old, a high-SEER heat pump or variable-speed inverter system can cut cooling costs by up to 40 % compared with older single-stage units.
