Our HVAC services cover everything your heating and cooling system needs. We handle emergency repairs when your system fails unexpectedly, routine maintenance to prevent problems, and full system installations when it’s time for an upgrade.

For Rochester homeowners, we understand that your HVAC system faces unique challenges. Winter temperatures that can drop below zero put serious demands on heating systems.

Whether you’re dealing with an immediate problem or planning ahead with preventive maintenance, our team has the experience to handle residential HVAC systems properly. We work on furnaces, heat pumps, central air systems, and ductwork, always focusing on solutions that make sense for your specific situation and budget.

Emergency response times depend on current demand and weather conditions, but we prioritize urgent situations like complete heating failures during winter or AC breakdowns during heat waves. Dempsey Comfort Club members receive priority scheduling for emergency calls. We understand that some HVAC problems can’t wait, especially when extreme weather threatens your family’s comfort and safety. When you call with an emergency, we’ll give you a realistic timeframe and keep you updated if conditions change. Our goal is always to restore your comfort as quickly as possible while ensuring the repair is done correctly.
First, check your thermostat settings and make sure it’s set to heat mode with the temperature set higher than the current room temperature. Verify that your circuit breaker hasn’t tripped and that your furnace switch is in the on position. Check if your air filter is extremely dirty, as this can cause safety shutoffs. If these basic steps don’t solve the problem, don’t attempt further troubleshooting yourself. Modern heating systems have multiple safety features that can shut down operation, and determining the cause requires proper diagnostic equipment. Contact us for a professional assessment rather than risking damage to your system or your safety.
Several issues can cause this problem, ranging from simple thermostat settings to more complex mechanical failures. Check that your thermostat is set to cool mode and the temperature is set below the current room temperature. A dirty air filter can also restrict airflow and cause cooling problems. However, the issue could also be low refrigerant levels, a malfunctioning compressor, or problems with your ductwork. Refrigerant issues require professional handling due to environmental regulations and safety concerns. Rather than guessing at the cause, having a technician diagnose the problem ensures you get the right solution and avoid potentially costly mistakes.
Most HVAC systems benefit from professional maintenance twice per year – once before the heating season and once before the cooling season. Rochester’s climate puts significant demands on both heating and cooling systems, making regular maintenance especially important. Spring maintenance prepares your AC for summer heat and humidity, while fall maintenance ensures your heating system is ready for New England winters. Regular maintenance catches small problems before they become expensive repairs, improves energy efficiency, and extends your system’s lifespan. Our Dempsey Comfort Club makes it easy to stay on schedule with automatic maintenance reminders and priority service.
The Dempsey Comfort Club is designed to help Rochester homeowners maintain their HVAC systems proactively rather than reactively. Members receive scheduled maintenance visits to keep their systems running efficiently, priority scheduling for service calls, and benefits that help reduce long-term costs. The program focuses on preventing problems before they disrupt your comfort or require expensive emergency repairs. Membership also includes follow-up communication to ensure your satisfaction and address any questions that arise after service visits. This approach helps you avoid the stress and expense of unexpected system failures while maintaining optimal comfort in your home year-round.

Our estimates include all necessary components, labor, and any additional work needed to ensure proper installation.
