Frequently Asked Questions
Let's talk about Cooling & Air Conditioning
Why is my AC blowing warm air?
This is one of the most common calls we get during a Rockford summer. It usually points to a refrigerant leak, a failed compressor, or simply a clogged air filter. Our technicians can quickly identify the pressure imbalance or electrical fault to get your home cool again.
How much does a new energy-efficient AC unit cost?
The cost depends on the size of your home and the SEER2 rating you choose. For homeowners in Machesney Park, we provide transparent, upfront estimates on high-efficiency systems that can significantly reduce your monthly summer utility bills.
What is the best way to cool a room without ductwork?
If you have a bonus room or a garage conversion in Roscoe that stays too hot, a ductless mini-split is the best solution. These units are whisper-quiet, highly efficient, and don’t require the major construction of adding new vents.
Why is my air conditioner making a loud banging or screeching noise?
Banging usually means a loose part, while screeching often points to a fan motor or belt issue. If you hear these sounds in your Rockton home, turn the system off immediately to avoid an expensive “total system failure” and call for a professional inspection.
How often should I schedule AC maintenance?
We recommend a professional tune-up once a year, ideally in the spring. In the Loves Park area, seasonal maintenance prevents 80% of common breakdowns and ensures your system is clean of cottonwood seeds and debris before the heat hits.
Can a smart thermostat really lower my electric bill?
Absolutely. By optimizing your cooling schedule based on when you are actually home, residents in Winnebago can see a noticeable drop in energy consumption. We can help you select and install a thermostat that syncs perfectly with your current system.
Why does my furnace smell like it’s burning?
When the heat is first turned on in Belvidere, it’s common to smell burning dust. However, if you smell “rotten eggs” (gas) or a metallic burning scent, it could be a cracked heat exchanger or electrical issue. Safety is our priority, so we recommend an immediate inspection if the smell persists.
Is it better to repair an old furnace or replace it?
If your furnace is over 15 years old and the repair cost is more than 50% of the value of a new unit, we typically recommend replacement. For families in Cherry Valley, upgrading to a 95%+ AFUE gas furnace can offer a massive return on investment through energy savings.
What causes a furnace to turn on and off every few minutes?
This “short-cycling” is often a safety feature triggered by a dirty flame sensor or an overheating heat exchanger. Our team serves New Milford and the surrounding areas to recalibrate these sensors and ensure your furnace runs through a full heating cycle.
Do you offer repair services for older boiler systems?
Yes. Many historic homes in the Rockford area rely on radiant heat or boilers. Our technicians are trained in the “old school” mechanics of boilers as well as modern hydronic systems to keep your radiators hot all winter.
What is a dual-fuel heating system?
A dual-fuel system combines an electric heat pump with a gas furnace. In South Beloit, this is a popular choice because the heat pump handles the cool autumn days efficiently, while the gas furnace kicks in during the sub-zero Illinois winter nights.
Why is my furnace blowing cold air?
If your thermostat is set to “Heat” but the air is cold, you may have a failed igniter or a pilot light that has gone out. We provide fast furnace repairs in Pecatonica to ensure you aren’t left in the cold during a winter storm.
How can I fix uneven heating between different floors?
In many multi-story homes in Byron, the top floor stays cold while the basement is warm. We specialize in “zoning” and ductwork balancing to ensure the air is pushed exactly where it needs to go for consistent comfort.
