Mesa Air Conditioning and Heating: Service, Repair, and Equipment Contractors

This local page provides resources and information about A/C and heating service, repair, maintenance, and installers in the Mesa, Arizona area. Included are the surrounding communities of Scottsdale, Tempe, Chandler, and Paradise Valley. Although there is some overlap, due to the population and demand, Phoenix has a separate page. The information here includes featured HVAC contractors plus a link to our handy printable grid to compare price quotes. You will also find sources of energy efficiency and equipment rebates, the ratio of hours of cooling and heating needed each year, and much more.

About HVAC contractors

The contractor you choose will make a big impact on your satisfaction and purchase of a new air conditioning and heating system. Why? They determine the size and type of equipment for your situation and they control the quality of the installation. If you have not yet seen them, in the top navigation menu on this page you will find quick tips and expanded topics on two essential topics: how to select the right HVAC contractor and how to buy a new heating and cooling system.

Due to relationships with their equipment distributors or ownership by a manufacturer, some air conditioning and heating contractors install a limited number of equipment brands. Many independents have a brand they prefer or for which they are dealers, but will order and install any brand of new equipment you prefer to buy. However, most all the contractors mentioned will perform repair and maintenance on any brand of central heater, furnace and air conditioner.

In addition to heating and cooling for indoor comfort and energy savings, an increasing number of HVAC companies perform air quality work such as air filters, dehumidifiers and humidifiers, ventilation and prevention of toxic carbon monoxide gas from your furnace. However, not all of these perform energy efficiency improvements to houses or buildings, such as the addition of solar screens or radiant barriers. If the service company you select does not perform conservation improvements on homes or buildings, they should be able to recommend another Mesa area company that does.

How to compare air conditioning and heating equipment price quotes

Air conditioning and heating systems are made of components or units, and these can be interchanged to yield many possible combinations of performance and efficiency. Additionally, based on the particular situation in your home or building, these components must be chosen and installed to accommodate them. For these reasons, comparing proposals, features, and prices can be more than confusing.

To help you sort through your options, use our free and printer-friendly cost comparison organizer found in the navigation on the top of this page. If you get multiple price quotes, it will save you a lot of time and headaches. This grid allows you to compare the essential features from contractor bids including: main components; equipment efficiency in SEER and AFUE; manufacturer’s and installer’s warranties; and equipment brand.

How the Mesa climate and resources affect your HVAC needs and decisions

On the heating and cooling map of the U.S. with 5 zones, the Mesa area lies in cooling zone 4 and heating zone 4. These require approximately 1986 cooling hours and 2105 heating degree-days per year. As a relative guide, the heating and cooling needs of the average Mesa home are evenly divided–needing about 1.1 times as much heating than air conditioning over a calendar year. Keep in mind that Mesa is located near the border of two zones. Differences in elevation or other topographical or climatic influences can cause microclimates, so be sure to rely on actual measurements or calculations from your heating and air conditioning contractor.

The arid Sonoran desert climate in south central Arizona cooks up some of the hottest summer weather of any major U.S. city. The area records high temperatures of 100 degrees Fahrenheit or hotter on many days from June to early September. In contrast, the area experiences relatively mild winters. There are numerous days (or parts of days) throughout the year when home heating and cooling may not be necessary. However, on these same days, a humidifier, whole house air filter or fresh air ventilator could make a huge difference in your comfort indoors. The fact that homes are now being constructed “tighter” to air infiltration, makes this especially relevant.

Pollen, allergies and air filters in Mesa

In the Mesa area, air filters are a necessity to many residents. Certain south central Arizona trees and smaller plants can strongly influence what type of air filter your occupants and your A/C system need. Some examples include ash, cedar and mulberry trees, ragweed, and other types of allergy producing pollen and molds. The daily pollen count and allergy forecast for the city and the surrounding areas can help you prepare and act accordingly.

Local utility and conservation providers

For the Mesa area, the DSIRE database lists energy efficiency rebates and incentives for APS -Arizona Public Service and the rest of the state in alphabetical order. In many cases, your A/C and heating contractor can coordinate all available energy conservation and rebate programs, from federal tax credits to local rebates and incentives.

The availability of primary fuels such as natural gas helps determine which central heating unit will give you the best combination of comfort and lower utility bills. Since natural gas is available in many Mesa neighborhoods, owners there have more gas furnaces rather than heat pumps. If natural gas prices climb faster than electricity rates, this trend might change. Also, recent advancements in “dual fuel” heat pump design are worth noting. In situations where a heat pump makes the best choice, some of the factors that affect air source heat pumps include the average daily temperature, fluctuations in temperature, and humidity. Other local conditions such as limestone located close to the surface limit the use of ground source heat pumps.

How a whole house approach includes the “envelope” in the load calculation

If you plan to get price quotes to buy a new A/C and heating system, look for contractors who will insert the heating and cooling demands of the Mesa climate along with the size and condition of your home or building “envelope” into a critical load calculation. For many reasons, allowing a rule of thumb load calculation based only on square footage or using the same size system as the old one without verification should be avoided. This calculation requires considerable expertise or software and interpretation.
