How quickly can you respond to HVAC emergencies in Weymouth?

Our technicians carry common parts and tools to handle most emergency repairs on the first visit. For Dempsey Comfort Club members, we offer priority scheduling which means you get bumped to the front of the line when your system fails. We understand that HVAC emergencies don’t wait for convenient times, so we work hard to restore your comfort as quickly as possible.

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 dirty or clogged. If these basic steps don’t solve the problem, don’t attempt further troubleshooting yourself. Modern heating 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’ll identify whether it’s a simple fix or something more complex.

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

This usually indicates a problem with your refrigerant levels, a faulty compressor, or issues with your system’s electrical components. Low refrigerant often means there’s a leak somewhere in the system that needs to be found and repaired before adding more refrigerant. Sometimes it’s a simpler fix like a dirty condenser coil or a malfunctioning thermostat. The key is getting an accurate diagnosis because the wrong repair can waste money and leave you still uncomfortable. Our technicians use proper testing equipment to pinpoint the exact cause and recommend the most cost-effective solution.

How often should I schedule HVAC maintenance in Massachusetts?

We recommend annual maintenance for most systems, ideally in the spring for cooling equipment and fall for heating equipment. Massachusetts weather puts extra stress on HVAC systems with our cold winters and humid summers, so regular maintenance is crucial for preventing breakdowns and maintaining efficiency. During maintenance visits, we clean components, check refrigerant levels, test safety controls, and identify potential problems before they cause system failures. Dempsey Comfort Club members get comprehensive maintenance that includes priority service and discounts on any needed repairs. Regular maintenance typically extends equipment life by several years and keeps energy costs lower.

What's the difference between repair and replacement for older HVAC systems?

Generally, if your system is over 10-12 years old and facing major component failures, replacement often makes more financial sense than expensive repairs. We look at factors like the cost of repair versus remaining system life, energy efficiency of your current equipment, and frequency of recent repairs. A good rule of thumb is if repair costs exceed 50% of replacement cost and your system is over 10 years old, replacement is usually the smarter investment. We’ll give you honest recommendations based on your specific situation and budget, not push you toward the most expensive option.

Do you service all HVAC brands and system types?

Yes, our technicians are trained to work on all major HVAC brands including Carrier, Trane, Lennox, Rheem, Goodman, and others. We service central air systems, heat pumps, ductless mini-splits, boilers, and furnaces. We keep common parts in stock for popular brands and can source parts quickly for less common equipment. Whether you have a basic single-stage system or a high-efficiency variable-speed unit, we have the expertise and tools to diagnose problems accurately and perform repairs correctly. We also stay current with new technology and can recommend upgrades that improve comfort and efficiency.
