FAQs
What does it mean that your HVAC technicians are “certified,” and why is it important for Crab Orchard homeowners?
Our technicians carry West Virginia HVAC Contractor licensure, EPA 608 refrigerant handling certification, and NATE (North American Technician Excellence) credentials. These third-party certifications verify that each technician has passed rigorous written and hands-on exams covering system sizing, airflow, ventilation codes, and refrigerant safety. For you, certification means two things: (1) code-compliant installations that protect your warranty and satisfy local inspection requirements in Crab Orchard and Raleigh County, and (2) accurate diagnostics that prevent repeat service calls and premature equipment failure.
How often should my home’s ventilation and indoor air quality be evaluated?
We recommend a complete air-quality and ventilation assessment at least once every two years, or sooner if you notice lingering odors, rising allergy symptoms, or recent remodeling work. Crab Orchard’s four-season climate causes homes to be tightly closed in winter and humid in summer, so filters, ERV cores, and ductwork are under constant stress. Annual HVAC maintenance includes a quick visual check, but a full IAQ evaluation uses particulate sensors, CO₂ meters, and humidity loggers to confirm the system is balancing fresh-air intake with energy efficiency.
What warning signs suggest my ventilation system needs professional attention?
Common red flags include uneven temperatures between rooms, musty or stale smells shortly after the blower stops, condensation on windows, visible dust buildup around supply registers, and higher-than-normal electric bills. Excess humidity (above 60%) or CO₂ readings above 1,000 ppm also point to inadequate air exchange. If anyone in the home experiences worsening asthma or allergy flare-ups, schedule an inspection; poor ventilation can allow pollen, pet dander, and microbial growth to circulate unchecked.
Do you offer energy-efficient air purification or ventilation upgrades, and will they reduce utility costs?
Yes. We install Energy Recovery Ventilators (ERVs), High-MERV media filters, UV-C germicidal lamps, and electronic air cleaners. ERVs transfer heat and moisture between incoming and outgoing airstreams, capturing up to 80% of the energy that would otherwise be lost, which can lower heating and cooling loads by 10–15%. Advanced filtration and UV systems improve air cleanliness without a major pressure drop, preserving blower efficiency. During an in-home estimate we perform a cost-benefit analysis so you can see projected payback before you commit.
How does professional duct cleaning improve indoor air quality and HVAC performance?
Over time, supply and return ducts collect dust, pet hair, construction debris, and microbial films that impede airflow. Using negative-pressure vacuums and rotary brush tools, our NADCA-compliant cleaning removes up to 40 lb of contaminants from an average Crab Orchard home. Cleaner ducts reduce blower strain, restore designed CFM airflow, and allow filters to last longer. Homeowners typically report a 15–20% reduction in airborne dust and may see utility savings because the system no longer has to overcome extra static pressure.
What happens during a routine HVAC maintenance visit, and how much downtime should I expect?
A standard tune-up lasts 60–90 minutes. We check refrigerant charge, static pressure, blower amperage, venting, and safety controls; clean or replace filters; sanitize condensate drains; and calibrate thermostats. For gas furnaces we perform a combustion analysis; for heat pumps we test defrost and reversing-valve operation. The system is only powered down for roughly 15 minutes while electrical and refrigerant inspections are performed. You can stay in the home during service, and we supply a written report with any recommended repairs or air-quality upgrades.
