How quickly can you respond to HVAC emergencies in Norfolk County?

We offer same-day service for most emergency calls throughout Norfolk County, and we understand that HVAC emergencies don’t wait for convenient times. When your heat goes out in winter or your AC fails during a summer heat wave, we prioritize getting a technician to your home as quickly as possible. Our trucks are stocked with common parts, so we can often complete repairs on the first visit. 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?

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 filter isn’t completely clogged. If these basics don’t solve the problem, don’t try to diagnose further yourself. Modern HVAC systems have safety features that shut them down when something’s wrong, and trying to override these can cause expensive damage. Call us for a proper diagnosis – we can often determine the issue quickly and get your heat restored safely.

Why is my air conditioner blowing hot air instead of cold?

This usually indicates a problem with your refrigerant levels, compressor, or outdoor unit. Low refrigerant often means there’s a leak somewhere in the system that needs to be found and repaired before adding more refrigerant. Sometimes the outdoor unit gets clogged with debris or the compressor isn’t running properly. These aren’t DIY fixes – refrigerant handling requires special licensing and equipment. We can diagnose the exact cause and explain your repair options. Continuing to run the system when it’s blowing hot air can cause additional damage to expensive components.

How often should I schedule HVAC maintenance in Massachusetts?

Massachusetts weather puts extra stress on HVAC systems, so we recommend professional maintenance twice a year – once before heating season and once before cooling season. This timing helps catch small issues before they become expensive problems during peak usage periods. Regular maintenance includes cleaning, safety checks, efficiency testing, and replacing filters. Systems that get regular maintenance last longer, break down less often, and run more efficiently. Our Dempsey Comfort Club makes it easy to stay on schedule with automatic reminders and member benefits.

What's included in your HVAC service calls and estimates?

Every service call starts with a complete diagnostic to identify the root cause of the problem, not just the symptoms. We explain what we found in plain language and provide upfront pricing before starting any work. Our trucks carry most common parts, so we can often complete repairs the same day. The service call includes testing your entire system after repairs to make sure everything’s working properly. We also check for potential issues that could cause future problems and give you honest recommendations about what needs attention now versus what can wait.
