Reno is a heating town
NOAA’s 1991–2020 climate normals for Reno-Tahoe International Airport list 4,669 heating degree days a year against 1,038 cooling degree days. Put simply, the heating load is roughly four and a half times the cooling load. December (892 heating degree days) and January (871) are the peak months, while July tops the cooling side at 379.
That means the furnace and blower carry most of the work here, from fall into spring, and the same blower pushes air through the coil and ducts all summer when the AC runs. A dirty blower wheel or coil affects both seasons.
Reno’s dry, windy climate adds to the load on filters: NOAA normals show just 7.35 inches of precipitation a year, with April through June the windiest months.
What EPA says about furnaces, coils and blowers
EPA’s duct cleaning guidance draws a clear line between ducts and equipment. It does not recommend routine duct cleaning, but it does recommend that fuel-burning furnaces, stoves and fireplaces “be inspected for proper functioning and serviced before each heating season to protect against carbon monoxide poisoning.”
On efficiency, EPA says: “Some research also suggests that cleaning dirty cooling coils, fans and heat exchangers can improve the efficiency” of a system, while “little evidence exists to indicate that simply cleaning the duct system will increase your system’s efficiency.” So if the goal is performance, the equipment is often where to look first.
EPA’s definition of a full cleaning also reaches beyond the ducts to “heat exchangers heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing, and the air handling unit housing,” and warns that “failure to clean a component of a contaminated system can result in re-contamination of the entire system.”
What furnace and coil cleaning usually covers
Inspection
The technician opens the furnace or air handler, checks the filter, blower and burners, and looks at the evaporator coil if it is reachable. Ask to see photos or the components themselves.
Blower cleaning
The blower wheel and housing collect dust that reduces airflow. Cleaning may involve removing the blower assembly, which is repair-type HVAC work.
Coil and drain pan
Dust on the indoor coil and debris in the condensate drain pan are cleaned with methods suited to the coil. EPA lists drain pans among the components a proper cleaning covers.
Heating safety check
For gas furnaces, EPA’s point about pre-season inspection for carbon monoxide safety applies. Ask what the visit includes.
Filter and report
A fresh filter goes in, and you get a written summary of what was cleaned and anything that needs repair.
Pairing equipment cleaning with air duct cleaning follows EPA’s whole-system point. After a smoke season, see wildfire smoke HVAC cleaning.
This is licensed HVAC work in Nevada
Here is how Nevada’s rules describe it, based on the state’s administrative code and statutes:
- NAC 624.380(3)(b) defines the C-21b Air-Conditioning subclassification as “the installation, repair, service and maintenance of equipment, devices, machinery, units and related ductwork which use evaporation, refrigeration, boilers or combustion for the control of air temperatures in structures.”
- C-21d Maintenance covers “the repair and replacement of any parts of existing units or systems of air-conditioning and refrigeration, including the compressors, motors, relays, coils, heat exchangers and other appurtenances.”
- The under-$1,000 handyman exemption in NRS 624.031 does not apply when “the work is of a type performed by a plumbing, electrical, refrigeration, heating or air-conditioning contractor.”
- Nevada has no separate duct cleaning license class. HVAC service work generally falls under C-21. Whether pure duct cleaning needs a license is not settled, but furnace, blower and coil work is HVAC service.
Nevada requires contractors to show their license number in their ads; check any company on the NSCB license search before you hire. Confirm the license is active and the classification fits the work. More in how to check a Nevada contractor license. This is general information, not legal advice.
Typical cost
| Item | Typical range |
|---|---|
| Furnace cleaning | $60–$150 (up to $500 with AC) |
| Whole-system duct cleaning (EPA and NADCA) | $450–$1,000 per system |
Coil cleaning has no reliable national price, so it isn’t listed. Be cautious of very low “whole house” specials: NADCA warns that cheap offers often leave out the air handler, blower fans and coils. See the cost guide for more.

Frequently asked questions
How often should a furnace be serviced?
EPA recommends that fuel-burning furnaces, stoves and fireplaces be inspected for proper functioning and serviced before each heating season to protect against carbon monoxide poisoning. In Reno, where heating demand is roughly four and a half times cooling demand by degree days, early fall is a natural time to schedule it before the December and January peak.
Does coil cleaning improve efficiency?
EPA says some research suggests that cleaning dirty cooling coils, fans and heat exchangers can improve a system’s efficiency. It also says little evidence shows that simply cleaning the duct system will increase efficiency. Results depend on how dirty the components are, so ask the company to show you the coil and blower before and after.
Do I need a licensed contractor for furnace or coil work?
Nevada’s C-21b air-conditioning subclassification covers installation, repair, service and maintenance of heating and cooling equipment and related ductwork, and the under-$1,000 handyman exemption does not cover heating or air-conditioning work (NRS 624.031). Check the company’s license and classification on the NSCB license search. This is general information, not legal advice.
What does furnace cleaning cost?
Cost guides put furnace cleaning at about $60 to $150 per furnace, and up to about $500 when an air conditioner is included. There is no reliable national price for coil cleaning on its own, so we don’t publish one. These are estimates, not quotes; local companies will price your system after seeing it.
Is furnace cleaning part of air duct cleaning?
It can be. EPA’s definition of duct cleaning includes heat exchangers, heating and cooling coils, drain pans, the fan motor and housing, and the air handler, and it warns that skipping a contaminated component can re-contaminate the whole system. Many quotes treat these separately, so ask each company exactly which parts are included.
