When something breaks down, it’s tempting to go the quick route and pay for repairs to get it up and running again. That quick-fix may seem the least expensive route now, but it may not offer the most value in the long run.
Three main factors to consider are:
- Life Expectancy
- Efficient Operating Cost
- Complete System Capability
Life Expectancy of Current System
Paying for repairs to an old or ineffective system often draw outs the inevitable. An older system that breaks down once is likely to continue breaking down. That means more emergency service calls and charges and the risk of damage to your home or other components of your cooling system.
Efficient Operating Cost
There’s also an ongoing cost factor to consider. Even six-year -old air conditioners are often considered inefficient by today’s energy efficiency standards. With new high-efficiency equipment, you could save up to 60% on your energy bills. In the long-run, installing a new cooling system can actually pay for itself in energy savings within a relatively short time.
Complete System Capability
When one component of your system breaks down unexpectedly, it’s easy to only focus on repairing or replacing that component. However, each part of your system works with the others to increase efficiency and reliability, therefore is it wise to consider the competence of the system as a whole and not individual parts. You can often save on installation costs if you have several components of your system (for example, a furnace and air conditioner) replaced at the same time
The best furnaces are efficient. They keep a home warm and comfortable. They provide steady, dependable performance year after year. And they are quiet, long-lasting and low in service frequency and cost.
When a furnace loses or wastes heat, it requires more energy to keep your home warm. Some furnaces lose heat through the walls of the furnace cabinet. Energy-efficient furnaces like Rheem’s full line of state-of-the-art models significantly reduce this loss with a blanket of insulation that lines the inside of the cabinet walls.
When a gas furnace is not in operation, most send a steady, wasteful draft of warm household air traveling up the venting system and out the roof. The Rheem Classic® Seriesand Classic® Plus Lines – feature an induced-draft blower that works in conjunction with a hot surface ignition system to pull hot gases through the heat exchanger at a constant and controlled rate of flow. As the burner cycles off, the draft blower stops, keeping the heating air in the system.
Pilot lights also can be wasteful. The electric ignition in many of Rheem’s furnaces eliminates the need for a constantly burning pilot. This feature alone gives up to 6% higher efficiency. And in combination with an induced-draft blower, can improve furnace efficiencies by over 20%.
Most gas furnaces vent combustion by-products and gases by allowing the warm air to rise naturally. However, on occasion, proper venting of combustion by-products may be restricted due to blockage, deterioration of venting systems, malfunctions or other causes.
The Rheem induced-draft blower maintains a constant draft through the heat exchanger, which assures proper venting of the furnace combustion chamber. Rheem also features a pressure switch which continuously monitors venting; and in the event it senses a vent flow restriction, it will automatically shut down your heating system for your safety.
The most efficient furnaces tap the energy of the hot vent gases – which can reach temperatures of 500 degrees Fahrenheit, and more. The Rheem Classic Series® 2-Stage 90 Plus gas furnace does this by routing the hot gases through a secondary heat exchanger. This step captures the otherwise wasted heat—using it to preheat the household air—and delivers AFUE ratings up to 95%
A high-efficiency furnace generally wears a higher price tag, but it can make up the difference by reducing operating costs over the long run. And with today’s consumer interest in efficiency, such equipment enhances the bottom line of your home.
Definitely. Features to look for include heat exchangers that resist corrosion, direct-drive blower units, induced draft blowers, pressure switches, and an insulated blower compartment, which helps minimize operating noise.
You also should ask your contractor if the manufacturer of the brand you’re considering quality-checks and tests every unit before it leaves the plant.
And be sure to check out the terms of the Limited Warranty. Quality manufacturers put a convincing warranty behind their work. Rheem furnaces, which include all the features described here, offer one of the very best. Even the primary and secondary heat exchangers in the Rheem 90 Plus® are protected by a Limited Lifetime Heat Exchanger Warranty.
Depending on your personal preference, comfortable and efficient temperature setting can range between 76-78 degrees for cooling and 68-70 degrees for heating.
Not usually, on a cold night a heat pump’s outdoor coil will freeze and it must be defrosted to preserve the unit’s heating efficiency. During this process the system will shift modes and may make loud whooshing noises.
Check the settings on your thermostat. If you want heating, make sure the temperature control selector is set below room temperature and the SYSTEM switch is on the HEAT or AUTO position. The FAN switch should be set to AUTO.
Check the air filter(s) for your air conditioner and replace if necessary.
Check the breakers for your air conditioning system. There will be one for the indoor air handler/furnace unit and one more for the outdoor condensing unit. If one of them has been tripped it can be reset by first moving it to the OFF position and then back to the ON position.
Houses with a gas furnace can check to see that the gas valve on the side of the furnace is turned to the “On” position. If the valve was off reset the breaker to the furnace by turning it off then back on again to reset any fault on the furnace. This will allow it to try and fire again if there is a demand for heating.

Gas Outages and Leaks
Know what to do in case of a gas leak or outage:
Natural gas is reliable and safe when used properly and equipment is properly maintained and inspected by a qualified contractor.
Learn to recognize a natural gas leak
If you suspect a leak, immediately call Xcel Energy at 800-895-2999 or 911 in an emergency.
Use your senses to recognize a potentially dangerous natural gas leak:
Smell: Natural gas is odorless except for the harmless odorant we add to help you detect a leak. The added odorant, called mercaptan, has a sulfur-like smell, similar to a rotten-egg.
Hear: A leak may produce a noise that ranges from next to nothing to a slight hissing or blowing sound to a loud roar – depending on the leak’s size and pressure.
See: A leak may cause dust, dirt or debris to fly, or create blowing or continuous bubbling movement in water. It also can cause a spot of dead or discolored vegetation in an otherwise green area.
Know how to respond to a natural gas leak
When an odor is persistent or seems to be everywhere, or it seems to linger longer than normal for your appliance’s operation, these could be signs of a gas leak inside your home or with an outside line.
Upon detecting such an odor, immediately get everyone out of your home or building, move a safe distance away and then call for help. Because an electric spark can ignite an explosion, remember to follow these tips:
- Do not turn on or turn off electrical switches.
- Avoid using electric appliances such as garage door openers or telephones of any type.
- Do not start up or shut down motor vehicles or any other electrical equipment.
- Do not strike a match. Avoid open flames or other ignition sources.
- Move to a location a safe distance away from your home when the odor is outdoors.
- Call Xcel Energy at 800-895-2999 or 911 in an emergency.
- Stay away until Xcel Energy or the emergency responders have told you it’s safe to return.
