Common repair situations
Tell us what the system is doing.
No cooling
The system will not start, the air feels warm, airflow is weak, or the home does not reach the thermostat setting.
No heat
The heating system is not starting, is cycling strangely, or cannot maintain comfortable temperature.
Other symptoms
Noise, water near equipment, thermostat problems, uneven rooms, constant running or another issue you want evaluated.
What happens next
Repair first when repair is the right first step.
The goal is to solve the current problem first. If the system's age, repair history or condition makes replacement worth considering, MAC HVAC will explain why and let you compare the options.
- ZIP and service-area confirmation
- System type and symptoms
