Louisville 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 installation in metro Louisville, Kentucky. This information includes selected 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, local HVAC schools, and 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. 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.

Most air conditioning and heating contractors stock 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 A/C units.

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 these perform energy efficiency improvements to your structure. If the service company you select does not perform conservation improvements on homes or buildings, they should be able to recommend another Louisville company who can if it is needed.

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 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 button 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 most 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 Louisville climate and resources affect your HVAC needs and decisions

On the heating and cooling map of the U.S. with 5 zones, Louisville lies in cooling zone 3 and heating zone 2. These require approximately 1402 cooling hours and 3784 heating degree-days per year. As a general guide, the average Louisville home would need 2.7 times more heating than air conditioning over a calendar year. Keep in mind that Louisville is located near the intersection of two zones on the map. Differences in elevation, large bodies of water, or other topographical elements can cause microclimates, so be sure to rely on actual measurements from your heating and air conditioning contractor.

The humid subtropical climate has its northern border near Louisville. This area of convergence of fronts brings volatile temperatures and occasionally storms. In spite of the extremes, there are numerous days in the year when neither heating nor cooling are necessary. On these days, a dehumidifier, whole house air filter or fresh air ventilation could make a big difference in your indoor comfort.

Pollen, allergies and air filters in Louisville

In Louisville air filters for pollen are a necessity to some residents. Certain northern Kentucky trees and plants can influence what type of air filter your A/C system and occupants need. Examples include birch, cedar, and elm trees, ragweed (usually fall), and other types of allergy producing molds and pollen. The daily pollen count and allergy forecast for the city and the surrounding metropolitan areas in Clark and Jefferson Counties can be found here.

Local utility and conservation providers

Louisville Gas & Electric has energy conservation programs including a free programmable thermostat in certain zip codes. Also, the regularly updated DSIRE database lists local to statewide energy efficiency rebates and incentives. In many cases, your A/C and heating contractor can coordinate all available energy conservation and rebate programs–from local utility provider rebates to manufacturer incentives and even federal tax credits.

The availability of primary fuels such as natural gas or heating oil can determine which kind of central heater will give you the best combination of comfort and lower utility bills. Since natural gas is generally available in Louisville, many owners have gas central furnaces. This is typical for areas with extended periods of cold weather. If natural gas prices climb faster than electricity rates, this trend might 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. Local conditions such as rock or stone located close to the surface can limit the use of ground source heat pumps in some areas.

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

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