Furnace not heating?

Step 1. Go to your thermostat and make sure the thermostat is set at least 3 degrees higher than the current room temperature.

Step 2. Go to you’re  main electrical panel and make sure the furnace breaker is all the way in the on position.

Step 3. Go to where your furnace is located and make sure the electrical switch on or near the furnace is in the “ON” position.

Step 4. Do you hear the fan running but do not feel any heat?

Step 5. Go to your furnace and check to make sure your gas valve ( the knob on the black iron pipe next to your furnace) is turned parallel  and running with the length of pipe.

Step 6. Is the filter clean?.

Step 7. Do you smell any unusual odors , gases, or burnt mechanical parts?

Step 8. Call Comfort Control Solutions at (509) 534-2199 (208)  277-4253


This is probably the most common Summer-Time Complaint!

Step 1. Go to your thermostat and make sure the thermostat is set at least 3 degrees lower than the current room temperature.

Advice from the experts

If you are wondering whether you should turn off the air conditioner so you can open a window to enjoy a break in the warm weather, here is some advice: do not continually turn on and off your air conditioner to adjust to the changing warm weather patterns outside. If you want to open a window to get some fresh air, it is better to leave your air conditioner on rather than turning it off. If the inside of the house gets hot and you have to turn the air conditioner back on then your air conditioner has to work harder to cool down your house and everything in it.


Gas furnaces with higher ratings cost more than those with lower ratings but may save you more money down the road. A minimum rating of 78% is established by the government in 1992. Many furnaces have an efficiency rating of about 60% prior to 1992.

The mid-efficiency furnaces are also called ‘induced draft furnaces’ or ‘non-condensing furnaces’. The mid-efficiency furnace offers the bare minimum of 78% efficiency up to about 80%.

The high-efficiency furnaces are also known as ‘condensing furnaces’ or ‘sealed combustion furnaces’. The high-efficiency furnaces has an AFUE rating as high as 96%. Some furnaces use a two-stage valve and an efficient variable-speed motor to raise comfort and effectiveness.

Air conditioning

Before each cooling season, it is recommended that central air conditioners get a professional tune-up. This is the biggest step to preventing major malfunctions in an AC unit.

Every month, especially during the summer months, remove any leaves or debris from outdoor condenser units.

If possible, shade the outdoor compressor unit. Air in shaded space is typically 5 to 6 degrees cooler than the surrounding air. Proper shading can be up to 10 percent more efficient over a cooling season.


When you want to achieve rapid temperature change for comfort, do not set the thermostat higher or lower than the desired temperature. That will not change the temperature any faster— it just makes the system work longer.

Air filters

It's best to have professionals conduct inspections and adjustments on your furnace. There are some things that homeowners can do themselves, however -- such as changing air filters on a regular basis

Changing your air filters on a regular basis can greatly reduce your operating and maintenance costs for both heating and air conditioning. Once a month is recommended. One useful tip to help you remember is to schedule around the time you pay your energy or fuel bill.

A dirty filter will restrict airflow from your gas furnace.

Here’s how to change a replaceable filter:

1) Turn off the power to the unit.

2) Look for the door or panel that conceals the blower; sometimes this is marked “Filter.” Lift this door or panel off its holding hooks, or unscrew its retaining screws to remove it.

3) Standard filters are mounted next to or under the blower motor. Slide the filter out along its tracks. Check to see whether it is a disposable filter or intended to be cleaned and replaced—this information should be marked on the filter’s edge, along with directions for cleaning, if applicable. If it’s a disposable filter, its size will likely be printed on the frame’s edge. Make a note of it.

4) Buy a replacement, and slide it into place, noting that arrows stamped on the side indicate the proper direction of airflow; be sure you face these in the proper direction.

What over 500 surveyed contractors say...

A top leading consumer magazine recently surveyed over 500 contractors and reported the following tips on purchasing a central air-cooling system.

Choose the right-sized air conditioning system. If it is too small, then it won't cool properly; if it is too large, then it won't dehumidify properly.

Beware of replacing only one of the two main components if shopping for a replacement system. Replacing only the indoor or the outdoor unit of a system may result in a mismatch that compromises efficiency. Contractors also said these systems are more repair-prone than systems where the two units have been bought and installed together.

 One-fifth of the contractors surveyed said the primary reason for their service calls was improper application or incorrect installation.

Maintain your system properly. At least 40 percent of surveyed contractors said that service calls were primarily the result of improper maintenance. An experienced contractor like Comfort Control Solutions is specially dedicated to ensure you never have to face these common problem’s.

HVAC Glossary of terms.

CONDENSER FAN - a fan that passes air over the condenser coil to facilitate the removal of heat from the refrigerant.

DECIBEL (dB) - a unit of measure of sound.

DUCT/DUCTWORK - a network of metal, fiberboard or flexible material flowing throughout a space which delivers air from an HVAC unit to the respective zones of a home or office.

EER - "Energy Efficiency Ratio"

EFFICIENCY - rating of HVAC equipment comparing how much energy is used and how much heat is produced. A unit rated ar 50% produces only $.50 of heat for each dollar spent.

EVAPORATOR COIL - a device that is designed to absorb heat in the air in order to change the liquid refrigerant that flows through it into a vapor

FHR - "First Hour Rating", amount of water (in gallons) a conventional storage tank type hot water heater can deliver in the first hour of use when tank is full.

HEAT EXCHANGER - a device through which heat is transferred to a cold area or surface.

HSPF - "Heating Seasonal Performance Factor". This factor rates the efficiency of the heating portion of the heat pump.

KILOWATT - 1,000 Watts, or "kW."

KWH - "Kilowatt Hour", measurement of watts used per hour.


REFRIGERANT - a gas or liquid used in air conditioning systems which condenses under pressure and in the process decreases in temperature. Commonly known refrigerants are "R-22", "R-410A".

R-22 common name for HCFC, (hydro-chlorofluorocarbon), a refrigerant gas used in HVAC equipment for nearly 50 years. Recent studies show that HCFC type refrigerants contain chlorine, an ozone-depleting agent and will be phased out of production by January 1, 2010.

R-410A - common name for "HFC", (hydro-fluorocarbon) a newer refrigerant gas used in HVAC equipment as it is more environmentally friendly than R-22.

REFRIGERANT LINES - tubing through which a refrigerant gas passes.

SEER - "Seasonal Energy Efficiency Rating". The higher the SEER rating, the more efficient the unit.

SPLIT SYSTEM - an HVAC system which uses indoor and outdoor components to perform heating and cooling.

SRN - "Sound Rating Number", the lower the SRN the quieter a unit is rated.

THERMOSTAT - temperature measuring and control device.

TON - 12,000 BTUs, (see BTU definition).

WATT/WATTS - unit of measure of electrical energy.

ZONE - a defined area within a building where heat and cooling are controlled by a thermostat. In building with only one zone, a single thermostat controls temperature throughout the building. HVAC systems with multiple zones can send heat or cooling to a particular room or area.
