Everything Your System Needs

We handle emergency repairs when your heating system won’t turn on or your AC stops cooling. Regular maintenance keeps your equipment running efficiently and catches problems before they become expensive failures.

For older systems that are costing more to fix than they’re worth, we install new energy-efficient equipment that actually lowers your utility bills. Our Dempsey Comfort Club membership gives you priority scheduling and exclusive benefits.

Whether it’s a quick repair, annual maintenance, or complete system replacement, you’re working with the same local team that knows your equipment and your home. No surprises, no runaround, just reliable service when you need it.

We prioritize emergency calls, especially during extreme weather when your heating or cooling system failure affects your family’s safety and comfort. Most emergency calls get same-day service, and we work evenings and weekends when needed. Our goal is to get your system running again as quickly as possible, not leave you waiting until it’s convenient for us. When you call with an emergency, we treat it like one.
First, check your thermostat settings and make sure it’s set to heat mode with the temperature higher than the current room temperature. Check your circuit breaker to ensure power is getting to the unit. Look at your air filter – a completely clogged filter can shut down some systems. If these basics don’t solve it, call us. Don’t try to force the system to work or attempt repairs yourself, as this can create bigger problems and safety hazards.
Your heating and cooling systems should be serviced annually – heating system in fall before winter, cooling system in spring before summer. Regular maintenance catches small problems before they become expensive failures, keeps your energy bills lower, and extends your equipment’s lifespan. During maintenance, we clean components, check refrigerant levels, test safety controls, and identify any parts that need attention. It’s much cheaper than emergency repairs.
Several things can cause this problem. Your outdoor unit might have lost power or tripped a breaker. Low refrigerant from a leak prevents proper cooling. A dirty air filter restricts airflow and can cause the system to overheat and shut down. The thermostat might be set incorrectly or malfunctioning. Some of these are simple fixes, others require professional repair. We can diagnose the exact cause and get your AC cooling properly again.
If your system is over 15 years old and needs frequent repairs, replacement usually makes more sense financially. Rising energy bills, uneven temperatures throughout your home, and constant breakdowns are signs your equipment is failing. We’ll give you honest advice about whether repair or replacement is the better investment. Sometimes a simple repair gets you several more years, other times you’re throwing money at a system that’s reached the end of its useful life.
Comfort Club members get priority scheduling for both routine maintenance and emergency calls. You receive annual tune-ups for your heating and cooling systems, plus discounts on repairs and replacement equipment. Members also get extended warranties on our work and preferred pricing on additional services. It’s designed for homeowners who want to maintain their systems properly and have priority access to our services when problems arise.
