Furnace Repair, Installation & Service in Mesa & Gilbert, AZ

Isley’s, your Furnace repair, installation and maintenance CONTRACTOR

Isley’s Home Service’s certified master heat pump technicians look at several factors in a home or business before we recommend a new heating-and-cooling system:

• Duct size
• US EPA’s ENERGY STAR rating
• Energy Efficient Ratio (EER)
• Seasonal Energy Efficiency Ratio (SEER)
• Windows
• Thermostats
• Capacity or size of a new heating and cooling system
• Many other factors, such as how many people live in your home or work in your business and how many heat-generating appliances and equipment you have

If you think your home or business is ready for a new heating and/or cooling system, please call Isley’s Home Service at 480-736-1805 to schedule a consultation. Read more about factors to consider when buying a new HVAC on our A/C Replacement Page.

How Furnace and Heat Pump Efficiency is Measured

• AFUE – Annual fuel utilization efficiency is a widely used measurement of a furnace’s efficiency. It measures the amount of heat delivered to your house, compared to the fuel you used to get it there. So, it your furnace has an 80% AFUE, it converts 80% of the fuel into heat while 20% is lost.
• Btu – The amount of heat energy needed to raise the temperature of one pound of water by one degree F is measured in British thermal units. In HVAC terms, Btu measures how much heat a heating unit produces and how much energy a cooling unit uses to remove heat from the air.
• HSPF – Heat seasonal performance factor is a term that describes a heat pump’s efficiency. The higher the number, the better the heat pump performs. An HSPF of 8 or higher is considered high efficiency.

Types of Furnace Heating Systems Used in Arizona

You have several choices for heating your Arizona home, and the best option depends on:

• The size of your home
• Your budget
• The age of your home
• How well your home is insulated
• The fuel source for your HVAC unit(s) – natural gas, propane, solar, electric, etc.
• The climate – Arizona is a mild climate, so our options are different from those who live in northern states
• Your home’s distribution system – most Arizona homes have forced-air systems and air ducts

The most common types of heating systems in Arizona are heat pumps and natural gas furnaces. If you are from another state, you might be familiar with other heating systems, such as propane furnaces, baseboard heat and steam radiant heat, but those are less common in the Phoenix area.

How Heat Pumps Work

A heat pump works in a similar way that a refrigerator works. It extracts heat from air and moves it elsewhere. So, in the winter, it extracts warmth from the outside air and pushes or transfers it into your home. In the summer, it works in reverse by extracting warm air from inside your home and moving it outside. Because it moves heat, rather than generating it, it’s more energy efficient.

Which Heat Pump Should I Get?

Look for a heat pump that has a high SEER rating. The US Environmental Protection Agency created SEER ratings to help homeowners and businesses choose HVAC systems that are efficient and not expensive to operate.

Another factor to consider is heating season performance factor (HSPF), which is a measurement of the efficiency of the air source for heat pumps. The higher the HSPF, the more efficient the unit is.
