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. Look at your air filter – a completely clogged filter can cause some systems to shut down as a safety measure. If these basic checks don’t solve the problem, don’t attempt any other troubleshooting yourself. Modern heating systems have safety features that shut them down when something’s wrong, and trying to override these can create dangerous situations or expensive damage.

Why is my HVAC system blowing hot air when I need cooling?

This usually indicates a problem with your air conditioning system while the fan continues running. Common causes include refrigerant leaks, failed compressor components, or electrical issues preventing the cooling cycle from operating properly. Sometimes it’s a simple thermostat problem, but often it requires professional diagnosis to identify whether you’re looking at a repair or if the system has reached the end of its useful life. Don’t keep running the system if it’s only blowing hot air – this wastes energy and can sometimes cause additional damage to components that are still working properly.

How often should I schedule HVAC maintenance in Massachusetts?

Massachusetts climate puts extra demands on HVAC systems with cold winters and humid summers, so annual maintenance is essential for most homes. Ideally, schedule heating system maintenance in early fall before you need it regularly, and cooling system maintenance in spring before the hot weather hits. If you have a heat pump that runs year-round, consider maintenance twice per year. Regular maintenance catches small problems early, keeps your system running efficiently, and helps prevent those middle-of-the-night emergency calls when your system fails during extreme weather.

What's included in your HVAC system diagnostic process?

A proper diagnostic starts with understanding what symptoms you’ve noticed and when they occur. Our technician checks electrical connections, measures system pressures and temperatures, tests safety controls, and examines all major components for signs of wear or damage. We’ll also check your air filter, ductwork connections, and thermostat operation. The goal is identifying the root cause of the problem, not just the obvious symptoms. You’ll get a clear explanation of what’s wrong, why it happened, and what options you have for fixing it, including honest advice about whether repair makes sense or if replacement would be more cost-effective long-term.

Do you service all brands of HVAC equipment?

Dempsey Energy works on most major HVAC brands and system types commonly found in Massachusetts homes. Our technicians carry diagnostic tools and common parts for the most popular brands, which means faster repairs in many cases. For older or less common equipment, we can usually still provide service, though some specialized parts might require ordering. During the diagnostic process, we’ll let you know if your particular system presents any service limitations. Our focus on residential HVAC means we understand the equipment most homeowners actually have, rather than trying to be everything to everyone.
