Questions and Answers

Can a new HVAC installation fix my heating system that keeps turning on and off (short-cycling) in my Plainview home?

Absolutely. Short-cycling is often caused by an improperly sized or installed system. Our expert HVAC installation or replacement service includes a precise load calculation for your Plainview home to ensure the new unit is the correct size. A properly matched system runs in longer, more efficient cycles, eliminating the short-cycling issue, improving comfort, and reducing wear and tear.

My gas furnace is short-cycling. Could it be a gas line or plumbing issue, not just the HVAC unit?

Yes, it's possible. While often an HVAC issue, problems like a restricted gas line or even venting issues related to your home's plumbing infrastructure can cause improper combustion and short-cycling. As a full-service HVAC and plumbing company, Clark & Son can perform a comprehensive inspection. We'll check your gas line, vents, and the furnace itself to diagnose the root cause accurately and fix it safely.

How does regular HVAC maintenance help prevent the common issue of improper system operation in Long Island homes?

Regular maintenance is key to preventing problems. Our HVAC system maintenance includes cleaning components, checking refrigerant levels, inspecting electrical connections, and verifying system controls. This proactive service catches small issues—like a dirty sensor causing short-cycling or loose wiring from a past improper installation—before they become major breakdowns. It keeps your system running as designed for efficiency and reliability through every Plainview season.
