Because of the dry climate and sparse cloud cover throughout Arizona, temperatures can vary dramatically, from day to night, and from season to season. Parts of Arizona located in the Sonoran Desert have warm daytime temperatures year round, while other parts of the state experience seasonal coldness regularly. The average daily temperatures of Yuma, which is located near Arizona’s southwestern corner, range from 43° to 67 °F (6° to 19 °C) in January, and from 81° to 106 °F (27° to 41 °C) in July. With summer maximum average highs of 93° F and relative humidity over 75 percent, air conditioning systems work at capacity. Inspection at the beginning of summer by professional air conditioning repair or installation technicians will ensure that everything is in proper working order. During winter, cold, dry air must be heated and humidified. A professional heating repair or installation service can add features like humidifiers to a furnace to combat dry air.

There are many ways to keep your heating, ventilation and air conditioning (HVAC) system working at optimum capacity, reducing the need for air conditioning and heating repair or installation of new units. Simple measures include cleaning and changing filters regularly, having semi-annual tune-ups and sealing ductwork. A well-insulated house reduces demand on HVAC units. Keeping your system working properly reduces the need for air conditioning repair or installation of a new unit and keeps you more comfortable.

If you want still lower energy costs, adjusting the thermostat can reduce consumption. Programmable thermostats regulate temperature settings for different times of day that correspond to your lifestyle. Temperatures can be reduced during winter or increased during summer when you are away from home. The thermostat automatically changes settings at specified times so that your house is the temperature you want when you return. Some units allow settings to be changed from mobile phones and the Internet. An air conditioning, heating repair or installation company like Cooper Climate Control from the Valley-Metro area can recommend high-performing brands.

Manual thermostats can be set back, and then re-set manually to the desired temperature. Improper installation of thermostats can increase energy bills by up to 7 percent. A professional heating repair or installation service can inspect your thermostat and ensure that it is installed correctly.

If you use window units rather than a whole-house HVAC system, trained technicians from your Heating & Cooling Specialists can suggest adjustments to enhance performance. A qualified professional air conditioning repair or installation service may recommend simple measures like insulating or adding Energy Star products that save both energy and money.
