Close Enough to Get There Fast

Next door

A Neighbor, Not a Dispatch Zone

Sleepy Hollow sits beside West Dundee and Elgin, so a technician is often already working nearby when you call.

Same day

Quick Turnaround on Repairs

Short travel means more of the day goes to the repair. Common furnace and AC parts ride on the truck, so most fixes finish in one visit.

Being close matters most when the house is cold or the AC has quit in a heat wave. Call (847) 224-2420 and we will tell you when we can be there, and if it can wait until morning we will say so.

No Heat or No Cool in Sleepy Hollow Right Now?

Before you call, check the thermostat mode and batteries, the furnace breaker and door switch, and the filter. In summer, if there is ice on the refrigerant line or indoor coil, switch the system to fan-only so it can thaw before we arrive.

If you smell gas, leave the house right away, call 911 from outside, and call your gas utility’s emergency line from outside before calling us. Otherwise, see emergency furnace repair and emergency AC repair, or call (847) 224-2420 and we will quote the after-hours visit before we dispatch.

Furnace Repair and Replacement in Sleepy Hollow

From November into March a furnace here runs against design temperatures near 0°F, and the first October cold snap is when weak links show. We repair every major brand: igniters, flame sensors, pressure switches, capacitors, inducer motors and control boards typically come in between about $150 and $900. A cracked heat exchanger is where we talk about furnace replacement instead of another repair.

A new 95% or 97% AFUE furnace qualifies for a Nicor Gas instant discount of $150 or $225 off the invoice, or $200 or $275 with a qualifying smart thermostat on the same invoice. Radiator and baseboard homes are covered as well: we repair hot-water and steam boilers of any brand, with $350 off a qualifying 95% AFUE boiler or $500 off a combination boiler. See boilers.

Air Conditioning, Heat Pumps and Ductless

May to September

AC Repair and Replacement

Capacitors, contactors, fan motors and refrigerant leaks on any brand, and R-32 replacements sized to the house, not the old label.

Below zero

Cold-Climate Heat Pumps

Amana S-Series inverter heat pumps keep heating well below zero, and a qualifying ducted system earns $900–$2,000 off from ComEd.

No ductwork

Daikin Ductless Mini-Splits

A finished basement, a sunroom or a bedroom the ducts never reached, with $500 or $1,000 off from ComEd on qualifying systems.

R-410A is being phased down and getting more expensive, so a large repair on an older condenser deserves a second look. See AC repair, AC replacement, heat pump installation, ductless mini-split installation and dual-fuel systems.

What a Service Call Costs in Sleepy Hollow

A repair starts with a flat diagnostic fee to find the fault. During office hours (9 a.m. to 5 p.m., Monday through Friday) the service call is $130; weekday evenings after 5 p.m. it is $180, and nights, weekends and holidays are $260. Each includes 30 minutes of travel and 30 minutes of diagnostics, and parts are extra. Once we know what failed, you get a flat-rate repair price and approve it before the work begins.

After-hours and emergency calls are priced higher than business-hours calls, and we quote that on the phone before we dispatch. Replacement quotes are free, written and include the ComEd or Nicor Gas discount. Financing prequalifies in about 2 minutes with no impact to your credit score.

Sleepy Hollow HVAC FAQs

How fast can you get to Sleepy Hollow?

Sleepy Hollow borders West Dundee and Elgin, so it is minutes from our shop. We schedule no-heat and no-cool calls as early as we can, and we tell you the arrival window on the phone rather than leaving you to guess.

Do I need a permit to replace a furnace or air conditioner in Sleepy Hollow?

We file the permit where the municipality requires one and handle the inspection as part of the installation.

Do ComEd and Nicor Gas discounts apply in Sleepy Hollow?

Yes. Sleepy Hollow is in ComEd and Nicor Gas territory, so both instant discounts come off the invoice at installation.

What does an after-hours call cost in Sleepy Hollow?

After-hours and emergency service calls are priced higher than business-hours calls, and we quote the call on the phone before we dispatch. Repairs are flat-rate and approved by you before any work starts.

Can you add cooling to a room that has no ductwork?

Yes. A Daikin ductless mini-split heats and cools a single room or several zones without ductwork, and qualifying systems get $500 or $1,000 off from ComEd.

Do you service all brands, and how do I book?

Yes. We install Amana and Daikin and repair every major brand of furnace, air conditioner, heat pump, boiler and mini-split. Call (847) 224-2420 any hour, or book online and pick a time that suits you.
