We maintain relationships with over 12,000 customers because we show up when we say we will and fix things right the first time. Our Dempsey Comfort Club members get priority scheduling and regular maintenance to catch problems before they become emergencies.

Everything Your System Needs

We handle emergency repairs when your heating or cooling system stops working. Whether your furnace won’t start on the coldest day of winter or your AC quits during a heat wave, we respond quickly to get you comfortable again.

Our installation services cover new system upgrades and replacements. If your old system is costing too much to run or breaking down constantly, we’ll help you choose an efficient replacement that fits your home and budget.

Regular maintenance through our Dempsey Comfort Club catches small problems before they become expensive emergencies. We clean, inspect, and tune up your system to keep it running efficiently and extend its lifespan. Members get priority scheduling and discounted service calls.

How quickly can you respond to emergency HVAC calls in Milton?

We offer 24/7 emergency service for heating and cooling failures. Response times depend on the severity of the situation and current call volume, but we prioritize emergencies like complete heating system failures in winter or cooling system breakdowns during heat waves. Dempsey Comfort Club members receive priority scheduling for all service calls. When you call for emergency service, we’ll give you a realistic timeframe and keep you updated if anything changes.

What should I do if my heating system stops working completely?

First, check your thermostat settings and make sure it’s set to heat mode at the right temperature. Check your circuit breaker to see if it’s tripped. Look at your furnace filter – if it’s completely clogged, that can cause shutdowns. If these basic checks don’t solve the problem, call us right away. Don’t try to fix heating system problems yourself, especially anything involving gas connections or electrical components. We’ll diagnose the issue safely and get your heat restored as quickly as possible.

How do I know if I need HVAC repair or full system replacement?

Age is the biggest factor – if your system is over 15 years old and needs frequent repairs, replacement usually makes more sense financially. If repair costs are more than half the price of a new system, replacement is typically the better choice. Systems that can’t maintain comfortable temperatures or cause energy bills to keep climbing are often beyond economical repair. We’ll assess your current system honestly and explain your options without pushing unnecessary replacements. Sometimes a good repair will give you several more years of reliable service.

What's included in your HVAC maintenance service?

Our maintenance service includes cleaning and inspecting all system components, checking refrigerant levels, testing electrical connections, lubricating moving parts, and replacing filters. We examine your ductwork for leaks and check thermostat calibration. You’ll get a detailed report of what we found and recommendations for any issues that need attention. Dempsey Comfort Club members receive annual maintenance visits, priority scheduling for service calls, and discounted repair rates. Regular maintenance prevents most emergency breakdowns and keeps your system running efficiently.

Why is my HVAC system blowing hot air when it should be cooling?

This usually means your air conditioning system has stopped working but the fan is still running. Common causes include refrigerant leaks, failed compressors, frozen evaporator coils, or electrical problems. Sometimes it’s as simple as a tripped breaker or blown fuse, but often it requires professional diagnosis and repair. Turn your system off and call us – running it when it’s not cooling properly can cause additional damage. We’ll identify the problem quickly and explain your repair options clearly.

Do you service all brands of HVAC equipment?

Yes, our technicians work on all major HVAC brands and models. We stock common parts for most systems and can source specialized components quickly when needed. Whether you have a newer high-efficiency system or an older unit that’s been reliable for years, we have the experience to diagnose and repair it properly. We’ll also let you know honestly when a system is beyond economical repair and help you choose the best replacement option for your home and budget.
