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 see if it’s tripped, and make sure your air filter isn’t completely clogged. If these basic steps don’t solve the problem, you likely have a more serious issue that needs professional diagnosis. Common causes include faulty ignition systems, gas supply problems, or failed components that require replacement. Don’t attempt to repair gas heating systems yourself – call a qualified HVAC contractor to diagnose and fix the problem safely.

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

When your AC blows hot air, it’s usually caused by one of several issues. A dirty air filter can restrict airflow and cause the system to overheat. Low refrigerant levels due to leaks prevent proper cooling. A malfunctioning compressor or faulty thermostat can also cause this problem. Sometimes it’s as simple as the thermostat being set to heat instead of cool, or the outdoor unit being blocked by debris. However, refrigerant issues and compressor problems require professional repair. If changing the filter and checking thermostat settings doesn’t fix it, you need an HVAC technician to properly diagnose and repair the system.

How often should I have my HVAC system serviced?

Most HVAC systems should be serviced twice a year – once in spring before cooling season and once in fall before heating season. Regular maintenance includes cleaning or replacing filters, checking refrigerant levels, inspecting electrical connections, lubricating moving parts, and testing system performance. This preventive approach catches small problems before they become expensive repairs and keeps your system running efficiently. In Bristol County’s climate, where systems work hard during both winter and summer, regular maintenance is especially important. Well-maintained systems last longer, use less energy, and are less likely to break down when you need them most.

How do I know if I need to replace my HVAC system?

Several factors indicate it might be time for replacement. If your system is over 15 years old and requiring frequent repairs, replacement often makes more financial sense than continued repairs. Rising energy bills despite normal usage suggest declining efficiency. Uneven heating or cooling, excessive noise, or difficulty maintaining comfortable temperatures are also warning signs. When repair costs exceed 50% of a new system’s cost, replacement is usually the better investment. An experienced HVAC contractor can evaluate your system’s condition, efficiency, and repair history to help you make an informed decision about repair versus replacement.

What size HVAC system do I need for my home?

HVAC system sizing depends on multiple factors beyond just square footage. Your home’s insulation quality, window types and placement, ceiling height, local climate, and even which direction your house faces all affect the calculation. An oversized system cycles on and off too frequently, wasting energy and failing to properly dehumidify. An undersized system runs constantly but never reaches comfortable temperatures. Professional contractors use Manual J load calculations to determine the correct size, considering all these factors. This ensures you get a system that efficiently maintains comfort while minimizing energy costs and maximizing equipment lifespan.

Do you provide emergency HVAC repair services?

Yes, we understand that HVAC emergencies don’t wait for convenient times. When your heating fails during a winter storm or your AC stops working during a heat wave, you need fast, reliable service. We prioritize emergency calls and work to restore your comfort as quickly as possible. Our technicians carry common replacement parts and have the experience to diagnose problems efficiently. For Dempsey Comfort Club members, emergency service includes priority scheduling. We recommend joining our maintenance program to reduce the likelihood of emergency breakdowns, but when they do happen, we’re here to help get your system running again.
