Serving homes and small businesses near Ferris.
Why is my AC running but not cooling the house?
Common causes include a dirty filter, thermostat setting, blocked outdoor condenser, frozen coil, low refrigerant, weak capacitor, duct leak, or airflow problem. Share what you have already checked when you submit the request.
What should I check before requesting AC repair?
Confirm the thermostat is set to cool, check the air filter, make sure vents are open, look for ice or water near the indoor unit, and check whether the outdoor unit is running. Stop running the system if you notice burning smells, loud electrical sounds, or ice buildup.
How often should HVAC maintenance be scheduled?
Many HVAC pros recommend maintenance before heavy cooling and heating seasons. Regular filter changes, clean outdoor equipment, clear vents, and professional checkups can help reduce breakdowns and improve comfort.
Should I repair or replace my air conditioner?
Age, repair cost, comfort problems, energy use, refrigerant leaks, and whether the system was properly sized all matter. If the unit is older, needs repeated repairs, or cannot cool evenly, ask for repair and replacement guidance.
What happens after I submit the form?
Your request is sent to Ferris Air & Heat for review. We may follow up if more details are needed before scheduling.

Can small businesses submit HVAC requests?
Yes. Light commercial HVAC requests can be submitted for shops, offices, rental spaces, and small commercial properties.
Why does my AC freeze up?
Frozen coils can happen when airflow is restricted, the filter is dirty, refrigerant is low, or the system runs while already iced over. Turn the system off and let it thaw before requesting help.
Why are some rooms hotter than others?
Uneven comfort can come from duct leaks, blocked vents, poor insulation, sun exposure, dirty filters, or a system that is not balanced for the home.
What does a maintenance visit usually check?
A maintenance visit commonly includes filter condition, thermostat operation, electrical components, refrigerant indicators, drain lines, coils, airflow, and outdoor unit condition.
Can indoor air quality help with dust or humidity?
Yes. Filter changes, airflow improvements, humidity control, duct concerns, and ventilation can all affect how clean and comfortable the air feels indoors.
When should I request heating repair?
Request heating help if the system will not start, blows cool air, cycles quickly, makes new sounds, gives off unusual odors, or cannot keep rooms comfortable.
Do I need to know the HVAC brand before submitting?
No. Brand and model details are helpful if you have them, but the form can be submitted with the symptoms, property type, and urgency.
Can I request HVAC help for a rental property?
Yes. Include whether you are the owner, tenant, or property manager, and describe any access details that may matter for scheduling.
What should I do if I smell burning or gas?
For possible gas, smoke, or electrical safety issues, leave the area if needed and contact the appropriate emergency or utility service before submitting a website request.
