FAQs
How often should I replace or clean my HVAC air filters in Johnson City?
In our region, pollen levels are high in spring and fall, and summers can be dusty, so most homes should replace or wash their filters every 30–60 days. Homes with pets, smokers, or residents with allergies should check filters monthly. A clean filter keeps airflow strong, lowers energy use by up to 15 %, and helps protect the blower motor from dust buildup.
What size or capacity HVAC system do I need for my Johnson City home?
The correct size depends on your home’s square footage, insulation level, number of windows, ceiling height, and even its orientation to the sun. A Manual J load calculation, performed by a licensed contractor, determines the exact tonnage (cooling) or BTU (heating) you need. Oversizing can cause short cycling and humidity problems, while undersizing will leave you uncomfortable on 90 °F summer days. We offer complimentary load calculations to make sure you get a perfectly matched system.
How can I improve indoor air quality during Johnson City’s allergy season?
Use pleated filters rated MERV 8–13, add a whole-home air purifier or UV light in the ductwork, and keep humidity between 35 % and 50 % with a dehumidifier in summer or humidifier in winter. Running your system in “fan-on” mode for an hour a day circulates air through the filter even when heating or cooling isn’t required. Routine duct cleaning and sealing also prevent pollen and dust infiltration.
What is the benefit of installing a programmable or smart thermostat?
Smart thermostats automatically adjust temperatures when you’re asleep or away, cutting HVAC runtime by up to 10 %. Many models provide remote monitoring, maintenance reminders, and energy-use reports. They pair well with TVA energy-efficiency programs and can be controlled by voice assistants or a phone app, giving you both comfort and lower utility bills.
Why is routine HVAC maintenance important in Johnson City’s climate?
Our hot, humid summers and cool winters put systems through year-round duty. A spring A/C tune-up and a fall furnace or heat-pump checkup keep coils clean, refrigerant at the correct charge, and safety controls calibrated. Regular maintenance can extend unit life by 3–5 years, cut energy costs by up to 20 %, and preserve manufacturer warranties that require documented service.
Do I need a dedicated ventilation system if I already have central air conditioning?
Yes—newer, tighter homes often lack enough natural air leakage to remove indoor pollutants. Energy recovery ventilators (ERVs) or heat recovery ventilators (HRVs) supply fresh outdoor air while exhausting stale indoor air and transferring heat and moisture to maintain comfort. This improves IAQ, reduces odors, and helps control humidity without placing extra load on your HVAC system.
