How quickly can you respond to HVAC emergencies in New Bedford?

We understand that HVAC emergencies don’t wait for convenient times, especially during New England’s extreme weather. Our response time depends on the current service load and the nature of your emergency, but we prioritize situations where people are without heat in winter or cooling during heat waves. When you call, we’ll give you a realistic timeframe and keep you updated if anything changes. Dempsey Comfort Club members receive priority scheduling for both emergency and routine service calls.

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

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 your circuit breaker to ensure the HVAC system hasn’t tripped a breaker, and replace your air filter if it’s extremely dirty, as this can cause some systems to shut down. If these basic steps don’t solve the problem, it’s time to call a professional. Heating system issues can involve gas connections, electrical components, or mechanical failures that require proper diagnosis and repair.

Why is my HVAC system blowing hot air instead of cold air?

This usually indicates a problem with your air conditioning system while the fan continues to run. Common causes include refrigerant leaks, a failed compressor, electrical issues, or a malfunctioning thermostat. Sometimes it’s as simple as a tripped breaker or a dirty air filter restricting airflow, but often it requires professional diagnosis. Don’t ignore this problem, as running the system when it’s not cooling properly can cause additional damage and higher energy bills.

How often should I have my HVAC system serviced in Massachusetts?

Most HVAC systems benefit from professional maintenance twice a year – once before the heating season and once before the cooling season. This is especially important in coastal areas like New Bedford where salt air can accelerate corrosion of HVAC components. Regular maintenance catches small problems before they become expensive repairs, keeps your system running efficiently, and extends its lifespan. Our Dempsey Comfort Club provides scheduled maintenance along with priority service and other benefits for customers who want to stay ahead of problems.

What makes HVAC service different for older homes in New Bedford?

Older homes often have unique challenges including outdated ductwork, insufficient insulation, and HVAC systems that weren’t designed for modern efficiency standards. Many older New Bedford homes have radiator heating systems, converted heating systems, or ductwork that’s been modified over the years. These systems require contractors who understand both old and new technology and can work with existing infrastructure while improving efficiency and reliability. We’ve worked with hundreds of older homes in the area and understand how to upgrade systems while respecting the character and limitations of historic properties.

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

Generally, if your system is less than 10-12 years old and the repair cost is less than half the cost of replacement, repair makes sense. However, if you’re facing frequent repairs, dramatically higher energy bills, or your system can’t maintain comfortable temperatures, replacement might be more cost-effective long-term. Age isn’t the only factor – we look at the overall condition, efficiency, and repair history of your system. During our diagnosis, we’ll give you honest information about whether repair or replacement makes more financial sense for your specific situation.
