Nashville 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 Nashville, Tennessee and the surrounding metropolitan area. This information includes featured HVAC contractors plus a link to our free, handy printable grid to compare price quotes. Here 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 recommend 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 navigation menu 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.
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 for which they are dealers, but will order and install any brand of new equipment you want. However, most all the contractors will perform repair and maintenance on any brand of central heater, furnace and air conditioner you have.
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 Nashville 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 create many combinations of performance and efficiency. Additionally, based on the particular situation in your home or building, these components must be chosen and installed accordingly. 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 Nashville climate and resources affect your HVAC needs and decisions
On the heating and cooling map of the U.S. with 5 zones, Nashville resides in cooling zone 3 and heating zone 3. This indicates 1402 cooling hours and 2942 heating degree-days per year. As a relative guide, the average Nashville home would need 2.1 times more heating than air conditioning over a calendar year. Differences in elevation, or other topographical influences can cause microclimates, so be sure to rely on actual measurements from a heating and air conditioning contractor.
This part of central Tennessee marks northern border of the humid subtropical climate of the southeast and the southern border of another humid continental zone in the midwest. Along with occasional storms, the area experiences four distinct seasons with long springs and autumns. Along with lots of pollen, the climate here brings many spring and autumn days in which home heating and cooling may not be necessary. On these same days, however, a dehumidifier, whole house air filter or fresh air ventilation could make a huge difference in your comfort.
Pollen, allergies and air filters in Nashville
Having to give extra attention to air filtration has become a necessity to some residents here. Certain central Tennessee plants can strongly influence what type of air filter you and your A/C system need. A few springtime examples of trees include the juniper, maple and oak trees. For the late summer ragweed is a common allergen. The daily pollen count and allergy forecast for the city and the surrounding suburbs and counties can be found here.
Local utility and conservation providers
Our research in the Nashville area yielded a no ongoing offers for energy efficiency rebates and incentives. We did find a Green Power Switch from the TVA worth noting. Generally, energy efficiency rebate programs come and go with the availability of funds anyway. 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, so check with them.
The availability of primary fuels such as natural gas or, to a lesser extent, heating oil can determine which type of heating unit will deliver the best combination of comfort and lower utility bills. Since natural gas is available in most of Nashville, many owners have gas central furnaces rather than heat pumps. If natural gas prices rise faster than electricity rates, this trend might change. In situations where a heat pump makes the best choice, some factors affecting air source heat pumps include the average daily temperature, fluctuations in temperature, and humidity. Other local conditions such as solid rock or stone close to the surface deter the use of ground source heat pumps.
How a whole house approach includes the “envelope” in the load calculation
If you plan to purchase a new A/C and heating system, look for a contractor who will insert the heating and cooling demands of the Nashville area climate along with the size and condition of your home or building “envelope” into a the critical load calculation. For many reasons, a rule of thumb load calculation based only on square footage or the same size system as the old one without verification should be avoided. This calculation requires a lot of expertise or special software.
