HVAC service guide
Find the right starting point for your system.
Air-Exx repairs, maintains, and replaces heating and cooling systems, then adds focused support for ductless, indoor air quality, geothermal, and light-commercial equipment. Start with what the system is doing now.
Straight answer
What is the difference between HVAC, air conditioning, and ventilation?
Air conditioning describes cooling. HVAC covers heating, cooling, and the equipment that moves conditioned air. Ventilation is the part that brings in, removes, or manages air movement. The right service route depends on the symptom, the equipment involved, and whether the goal is repair, maintenance, or a system change.
Choose by need
Nine services. Three useful starting points.
Something stopped working
Air conditioning repair and diagnosisWhen the air conditioner is running but the house is not cooling, the problem may involve airflow, electrical controls, refrigerant, a motor, a capacitor, or another system component. A diagnosis separates the symptom from the cause before repair options are presented.↗
Heating and furnace repairA heating system that will not start, blows cool air, or heats unevenly needs a diagnosis of the operating condition behind the symptom. Air-Exx checks the relevant system components, explains the finding, and presents firm repair options.↗
Emergency and after-hours HVAC serviceAir-Exx offers 24/7 availability to answer for emergency and after-hours HVAC needs. Call and describe what the system is doing, whether heating or cooling has stopped, and any condition that makes the situation urgent. If a call is not answered, use the separate text line.↗You are deciding what comes next
System replacement and installation optionsReplacement becomes worth considering when a repair is substantial, failures keep returning, comfort remains uneven, or the current equipment no longer fits the home's needs. Air-Exx evaluates the existing system and presents firm options without pushing one automatic answer.↗
Mini splits and ductless systemsA mini split can provide targeted heating and cooling where extending or relying on the existing system is not the best fit. Bedrooms, additions, garages, condos, offices, and other hard-to-serve spaces are common reasons to consider ductless equipment.↗
Geothermal and ground-source systemsA geothermal or ground-source system exchanges heat with the ground as part of heating and cooling the property. Whether it fits depends on the site, the building, existing distribution, installation conditions, and the owner's long-term comfort goals.↗You want to protect or improve the system
Preventative HVAC maintenancePreventative maintenance is a planned check of the heating and cooling system while it is still operating. The goal is to understand current condition, address routine care, and identify developing concerns before the next heavy-use period.↗
Indoor air quality and ventilationIndoor air quality work starts by identifying the concern and how the HVAC system moves air through the home. Filtration, purification, humidity control, ventilation, and airflow each address different conditions, so the right option depends on the system and the goal.↗
Light commercial HVAC and refrigerationAir-Exx provides light commercial HVAC and commercial refrigeration service, including work for restaurants and food service. The useful starting point is the equipment involved, how the problem affects operations, and whether the need is a repair, maintenance, or a broader system decision.↗A clearer first conversation
You do not need to diagnose it before you call.
Tell us what you hear, feel, smell, or see, when it started, and which part of the home or business is affected. Air-Exx can use that information to choose the right next step without asking you to name the failed part.
