Question Answers

My furnace in Monmouth keeps turning on and off quickly (short cycling). What should I do?

Short cycling is a common issue in our area, often caused by an oversized unit, a dirty filter, or a faulty thermostat. It strains your system and hikes up energy bills. We recommend scheduling an HVAC system repair service. Our technicians will diagnose the root cause, whether it's a simple fix like cleaning the flame sensor or a more complex component replacement, to restore proper, efficient operation and protect your furnace.

How can a plumbing inspection from Duke's help prevent carbon monoxide risks in my home?

While carbon monoxide (CO) is often linked to heating systems, faulty gas lines or improper venting for water heaters discovered during a plumbing inspection are also major risks. Our comprehensive plumbing inspection checks all gas fittings, connections, and venting systems for leaks, blockages, or corrosion. Identifying and repairing these issues ensures harmful gases are properly vented outside, adding a critical layer of safety to your Monmouth home alongside your CO detectors.

When is it time to consider a full HVAC replacement instead of another repair for my Monmouth home?

If your system is over 15 years old, requires frequent repairs, or struggles to heat/cool evenly, a replacement is often more cost-effective. Modern, high-efficiency HVAC installation not only resolves persistent issues like short cycling but also significantly lowers your energy bills and improves indoor air quality. For Monmouth homeowners, upgrading to a properly sized, modern system means reliable comfort, enhanced safety, and long-term savings, especially during our cold winters.
