Why is My Air Conditioner Blowing Warm Air?

Residents of Spokane know that when July and August rolls around, the only way to find relief from the rising temperatures is in the comfort of air conditioning.

Summer is the time of year when your air conditioning unit works tirelessly to combat the heat. If you find that your air conditioner is running but is not blowing cool air, there are a number of possible options.

Air Filter

A dirty air filter is the most common reason your air conditioner won’t work, or will block air flow. Check your air filter and replace it, if in doubt.

Thermostat

Your air conditioning unit will not work properly if your thermostat is set to the wrong commands or is defective. First, check to make sure your AC unit is set to the “on” position. If that doesn’t change anything, your next step will be troubleshooting the thermostat. Some beginning steps include changing the batteries, dusting the inside of your thermostat, adjusting the anticipator or completely rebooting the system.

Condenser Coils

Condenser coils need regular maintenance to keep your AC unit working properly! Since the condenser coil is responsible for producing cold air, any problems will cause it to malfunction.  We recommend you call a professional to evaluate any problems here, as a safety precaution.

Refrigerant

Refrigerant is the chemical that cools the air within your air conditioning system. A malfunctioning AC unit is a sign that your refrigerant may be low, leaking or blocked. The only way to be sure is with a diagnosis from a professional technician.

Ductwork

Ductwork is responsible for delivering cool air throughout your home. If your air conditioning is not working properly, there’s a chance your ductwork was poorly designed. Poor design often leads to leaking ducts, poorly sealed registers, little to no insulation and an overall loss in cool air being delivered to your home.

With new building codes in place, most homes built after 1979 are better insulated and much more tightly sealed. This helps reduce the amount of energy used to keep the home comfortable, but it also traps humidity and allergens in the home.

Dust and mold are often unseen to the naked eye, but can wreak havoc on the health of allergy sufferers. While you probably take the time to clean areas of your home where you know they will build up, what is lurking behind the walls in your home is quite often another story. Air ducts are a great place for dust and mold and other pollutants to proliferate and thrive. The warm environment allows mold spores to grow, and the forced air does its part to blow dust and other allergens all over your home. Here are five reasons you should consider getting your air ducts cleaned today.

In Spokane, a heat pump ranges in price from $4700 to $7000. The price of your heat pump will depend on a number of factors including size of your home, level of energy efficiency, installation variances and quality. The quality would be determined by a good-better-best offering and the variances would depend on the difficulty of the install. While this may be a hefty price tag, there is good news. Energy.Gov states that a heat pump can operate at about one quarter of the cost of a conventional heating/cooling appliance. That means big savings in the long run!

Additionally, there are often rebates available both from the manufacturers and/or your local utility company. Our experts are happy to help you determine what rebates may be available for you.

  • The furnace is a major part of a split or hybrid system. The furnace creates warm air to heat the home. 

  • The furnace can also work in conjunction with a condenser or heat pump to circulate cool air throughout the home. 

  • The furnace is comprised of a blower to circulate air, a gas valve and heat exchanger to heat the air. 

  • If combined with an air conditioner or heat pump, a coil is attached to the furnace.

  • According to the American Council for an Energy Efficient Economy (ACEEE), "Reducing your heating energy use is the single more effective way to save money and reduce your home's contribution to global environmental problems.

  • Recent technology advances have given us two and three-stage furnaces using variable-speed blowers, which can improve comfort within the home and further reduces energy consumption.

During the hotter times of the year, an Air Conditioner delivers cool, comfortable air to the home. The air conditioner sends refrigerant to the indoor coil, chilling the coil. After the refrigerant chills the coil, it absorbs the heat from the warm air and returns it to the air conditioner where it is released into the outside air. As air is passing through the coil, it also leaves moisture behind, reducing the humidity in the home.

Professor Dennis Buffington from the department of agriculture and biological engineering of Penn State University says "To make an "apples-to-apples" comparison of various forms of energy, the comparisons must be made on the basis of dollars per million BTUs." Below is an energy cost comparison to create 1 million B.T.U.s.
