We prioritize emergency calls, especially during extreme weather when heating or cooling failures can be dangerous. Response time depends on the situation and our current service load, but we understand that some problems can’t wait. When you call for emergency service, we’ll give you a realistic timeframe and keep you updated. Dempsey Comfort Club members get priority scheduling, which means faster response times during peak demand periods like heat waves or cold snaps.
First, check your thermostat settings and make sure it’s set to heat mode with the temperature set higher than the current room temperature. Check that your circuit breaker hasn’t tripped and that your furnace switch is on. Look at your air filter – if it’s completely clogged, replace it. If these steps don’t solve the problem, call us. Don’t attempt to repair gas furnaces yourself, as this can be dangerous. We’ll diagnose the issue safely and get your heat restored quickly.
Several things can cause this problem. Your air filter might be so dirty that it’s restricting airflow, causing the system to freeze up. Low refrigerant levels from a leak will also prevent proper cooling. Sometimes the issue is electrical – a bad capacitor or failed compressor. The outdoor unit might be dirty or blocked by debris. We’ll check all these possibilities during our diagnostic and explain what needs to be fixed to restore proper cooling to your home.
Most systems need professional maintenance twice a year – once before heating season and once before cooling season. This catches small problems before they become expensive repairs and keeps your system running efficiently. During maintenance, we clean components, check refrigerant levels, test safety controls, and replace filters. Regular maintenance typically extends equipment life and reduces energy costs. Our Dempsey Comfort Club includes scheduled maintenance visits so you don’t have to remember to call.
Our diagnostic is a thorough examination of your entire system, not just the obvious problem. We check electrical connections, test safety controls, measure refrigerant levels, inspect ductwork, and evaluate system performance. We also look at your thermostat operation and air filter condition. This comprehensive approach helps us find the root cause of problems and identify potential issues before they cause breakdowns. You’ll get a clear explanation of what we found and your options for repairs or improvements.
Yes, we regularly upgrade older homes to modern, efficient systems. However, older homes sometimes need additional work like electrical upgrades or ductwork modifications to support new equipment properly. We’ll evaluate your home’s specific needs and explain any additional requirements upfront. Modern systems can significantly reduce energy costs compared to older equipment, but proper installation is crucial for getting those benefits. We’ll help you choose the right system size and efficiency level for your home and budget.
