Comfort You Can Count On

You shouldn’t have to worry whether your heat will kick on during a January cold snap or if your AC will quit on the hottest day of summer. When your HVAC system works right, you forget it’s even there.

That’s exactly what you get with properly installed and maintained equipment. No more adjusting the thermostat hoping something changes. No more uneven temperatures between rooms or sky-high energy bills from an inefficient system.

Your home stays comfortable year-round while your system runs efficiently in the background. You save money on monthly utilities, avoid emergency repair calls, and get the peace of mind that comes with knowing your HVAC contractor actually knows what they’re doing.

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

We prioritize emergency calls, especially during extreme weather when your heating or cooling system failure affects your family’s safety and comfort. Response time depends on current demand and your specific location within our Norfolk County service area, but we work to get a technician to your home as quickly as possible. Dempsey Comfort Club members receive priority scheduling for all service calls, including emergencies. We’ll give you a realistic timeframe when you call and keep you updated if anything changes.

What should I do if my heating system won't turn on?

Start with the basics before calling for service. Check that your thermostat is set to heat mode and the temperature is set higher than the current room temperature. Make sure 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 some systems to shut down for safety. If these steps don’t solve the problem, you likely have a component failure that needs professional diagnosis. Don’t attempt to repair electrical or gas components yourself – that’s when you need an experienced HVAC contractor.

Why is my air conditioner blowing warm air instead of cooling?

Several issues can cause this problem, ranging from simple to complex. Your air filter might be completely blocked, restricting airflow and causing the system to malfunction. You could have a refrigerant leak, which requires professional repair and can’t be fixed by adding more refrigerant alone. The outdoor unit might be dirty or blocked, preventing proper heat exchange. Electrical problems can also cause the outdoor unit to stop working while the indoor fan continues running. A qualified technician needs to diagnose the specific cause because the wrong repair approach can make the problem worse or damage other components.

How often should I schedule maintenance for my HVAC system?

Most manufacturers recommend professional maintenance twice per year – once before the heating season and once before the cooling season. This schedule catches small problems before they become expensive repairs and keeps your system running efficiently. During maintenance, we clean components, check electrical connections, test safety controls, and verify that everything operates within normal parameters. Regular maintenance typically extends equipment life and maintains your warranty coverage. Norfolk County’s climate puts significant demands on HVAC systems, so staying on schedule with maintenance is particularly important here.

When should I replace my HVAC system instead of repairing it?

Consider replacement when repair costs approach 50% of a new system’s cost, especially if your equipment is over 15 years old. Frequent breakdowns, rising energy bills, and uneven heating or cooling throughout your home are also signs that replacement makes more financial sense than continued repairs. Newer systems are significantly more energy-efficient and reliable than equipment installed even 10 years ago. We’ll give you honest guidance about whether repair or replacement makes sense for your specific situation and budget. Sometimes a repair buys you time to plan for replacement, while other times replacement is the clear better choice.

Do you service all brands of HVAC equipment?

Yes, our technicians work on all major HVAC brands and most older equipment still in operation throughout Norfolk County. We maintain relationships with parts suppliers for both current and discontinued models, though parts availability can sometimes be an issue with very old systems. Our experience with different manufacturers helps us diagnose problems quickly and recommend the most cost-effective solution. Whether you have a high-end system or basic builder-grade equipment, we have the knowledge and tools to service it properly. We’ll also let you know if your equipment has known reliability issues that might influence your repair versus replacement decision.
