Read the guideFurnace Making Noise? What the Sounds Usually Mean
Every furnace makes some noise when it runs: a click, the small inducer fan spinning up, a soft whoosh when the burners light. New or louder sounds are worth paying attention to, because many of them point to a specific part. Here's what the common ones usually mean, and which ones mean you should turn the heat off.
Read the guideCarbon Monoxide and Your Furnace: What to Know
Carbon monoxide (CO) is a gas you can't see or smell. Gas furnaces, water heaters, stoves and fireplaces can all produce it if something goes wrong with how they burn fuel or send exhaust outside. Working CO alarms and a yearly check of your heating system are the two best protections.
Read the guideWhy Is My Furnace Blowing Cold Air?
Cold air from the vents when the heat is on is one of the most common winter calls we get. Sometimes it's a setting, sometimes it's the furnace protecting itself, and sometimes a part has failed. Here's how to tell, starting with the checks anyone can do safely.
Read the guideFurnace Leaking Water? What It Means and What to Do
Water on the floor around a furnace always has a cause, and most of the time it's a drain problem, not a broken furnace. Here's how to figure out where the water is coming from, what you can safely check, and when to call.
Read the guideShould You Repair or Replace Your Furnace?
Most furnace problems are worth repairing. But when a furnace is getting old, needs repairs more often or has a safety problem, replacing it can be the better choice. Here's how to think it through, and what we'll tell you if we're the ones looking at it.
Read the guideHeat Pump Aux Heat: What It Means and When to Worry
If you have a heat pump, you've probably seen "Aux" or "Aux heat" on the thermostat on a cold morning. Most of the time it's doing its job. Sometimes it's a sign the heat pump isn't carrying its share, and that shows up on your electric bill. Here's how to tell the difference.
Read the guideThermostat Screen Blank? What to Check First
A blank thermostat usually means it isn't getting power, and the heat or AC stops with it. The cause is often simple: batteries, a breaker or a switch. Sometimes the system shut itself off on purpose. Here's what to check, in order.
Read the guideFurnace Smells Like Burning? What's Normal and What's Not
The first time you turn the heat on each fall, a burning smell is common, and it usually fades on its own. Some smells mean it's time to turn the furnace off and call. Here's how to tell them apart.
Read the guideWhy Does My HVAC Keep Turning On and Off?
Short cycling means your heating or cooling system turns on and off more often than it should, running a few minutes at a time instead of completing a full cycle. It wastes energy, wears out parts faster and, in summer, leaves the house clammy because the AC never runs long enough to remove humidity. The cause can be anything from a dirty filter to an oversized system, so here's how to narrow it down safely.
Read the guideHeat Pump Not Heating? Understand the Symptoms
Census data shows that most homes in Georgetown and Nicholasville heat with electricity, and heat pumps are common across Central Kentucky. A heat pump behaves differently from a gas furnace: the air feels warm rather than hot, the outdoor unit makes different sounds, and in winter it periodically defrosts itself. Here's how to tell normal heat pump behavior from a real problem.
Read the guideShould You Repair or Replace Your AC?
There's no single age or dollar amount that makes replacement the right answer. An older system with a small, isolated problem is often worth repairing, and a younger system with a failed compressor sometimes isn't. Here's how to think it through, and what to ask any contractor before you decide.
Read the guideHVAC Maintenance Checklist for Kentucky Homes
Good HVAC maintenance is part homeowner habit and part professional tune-up. The homeowner part takes a few minutes a month. The professional part happens before the cooling and heating seasons. Here's the full checklist, including what a tune-up should actually cover.
Read the guideR-454B Refrigerant: What Kentucky Homeowners Need to Know
New central air conditioners and heat pumps now use a different refrigerant, most often R-454B, instead of the R-410A that was standard for years. If you already have an R-410A system, you don't have to replace it: it can still be repaired and serviced. The change matters most when it's time for a new system.
