The answer to 'should I get emergency HVAC service or' is that it depends on your specific situation. If your HVAC system has completely stopped working or you have a serious issue like a refrigerant leak, then it's best to call for emergency HVAC service. This ensures your home stays comfortable and you avoid further damage to your system. However, if the issue is minor like a thermostat problem or dirty air filter, you may be able to troubleshoot and fix it yourself or wait for regular service.
Emergency HVAC service provides fast response, usually within a few hours, to get your system back up and running quickly. This is important if your home is at risk of extreme temperatures. The downside is that emergency service typically costs more than regular maintenance visits. Regular HVAC service is generally less expensive, but you'll need to wait for an available appointment, which could be days or weeks out depending on demand.
