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

This page provides resources and information about A/C and heating service, repair, maintenance, and installers in metro Detroit, Michigan. This information includes HVAC contractors plus a link to our free and handy printable grid to compare price quotes. Here you will also find sources of energy efficiency and equipment education, the ratio of hours of cooling and heating needed each year and more.

About HVAC contractors

The contractor you choose will make a major impact on your satisfaction with 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, at the top of 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.

Most air conditioning and heating contractors stock and install a limited number of equipment brands. Some independent contractors will order and install any brand of new equipment you prefer to buy. Most of these service companies will perform repair and maintenance on all brands of central heaters, furnaces and air conditioners.

In addition to heating and cooling for indoor comfort and energy savings, many 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 them perform energy efficiency improvements to houses or buildings. If the service company you select does not perform conservation improvements on homes or buildings, they should be able to recommend another Detroit company who 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 mixed/matched to yield many possible combinations of performance and efficiency. Additionally, based on the particular attributes 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 at 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 warranties; and equipment brand.

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

On the heating and cooling map of the U.S. with 5 zones, the Detroit area lies in cooling zone 1 and heating zone 1. These require approximately 584 cooling hours and 4626 heating degree-days per year. As a general and relative guide, the average Detroit home would need 7.9 times more heating than air conditioning over a calendar year. Differences in elevation, proximity to the Great Lakes or other topographical influences can cause microclimates, so be sure to rely on actual measurements and calculations from your heating and air conditioning contractor.

The midwestern climate of Detroit is heavily influenced by the Great Lakes. Typical winters are long with moderate snowfall. Summers reach their average high of 83 degrees Fahrenheit in July with peaks exceeding 90 degrees. Still, there are some days in which home heating and cooling may not be necessary. However, on these same days, humidity control, a whole house air filter or fresh air ventilation could make a major difference in your comfort.

Pollen, allergies and air filters in Detroit

In Detroit air filters are a necessity to some residents. Certain southeast Michigan plants and trees can strongly influence what type of air filter you and your A/C system need. Some seasonal examples include elm, maple and cedar/juniper trees, ragweed in the fall, and other types of allergy producing pollen in the springtime. The daily pollen count and allergy forecast for Detroit and the surrounding metro areas such can be found here.

Local utility and conservation providers

The availability of primary fuels such as natural gas or heating oil can sometimes determine which HVAC equipment will give you the best combination of comfort and lower utility bills. Since natural gas is generally available in Detroit neighborhoods, many consumers have chosen gas central furnaces rather than heat pumps. If natural gas prices climb faster than electricity rates, this trend could change. 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.

In our research we have not yet located any utility companies providing energy conservation incentives the Detroit area. 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.

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 Michigan climate along with the size and condition of your home or building “envelope” into a critical load calculation. For many reasons, a rule of thumb load calculation based only on square footage or using the same size system as the old one should be avoided. This calculation requires considerable expertise or software and interpretation.
