Mississippi HVAC leads

How Mississippi homes are heated

Mississippi is an electric-heat state with an unusually large propane share. The Census Bureau’s table B25117 (ACS 2020-2024) has electricity as the main heating fuel in 436,778 of 801,788 owner-occupied homes, or 54.5%, the 7th highest share of the 50 states. Bottled, tank or LP gas heats 11.9%, 11th highest among the states.

For all occupied homes, renters included, table B25040 (2020-2024 ACS) shows 58.9% electric and 29.3% utility gas. Buyers look at this split to see what a typical system swap involves: a heat pump or electric furnace in most owner homes, a gas furnace in about a third, and propane-fired equipment in roughly one owner home in eight. These are housing shares; they do not say where requests come from.

Mississippi HVAC contractor licensing

The Mississippi State Board of Contractors licenses HVAC contractors under two laws, one for homes and one for commercial work, both reprinted in the board’s 2022 booklets.

• Residential work. Miss. Code 73-59-3(1)(d) requires any subcontractor, of any tier, doing heating, ventilation or air conditioning work, or mechanical, electrical or plumbing work, on a residential construction or improvement project to be licensed by the board, no matter the dollar amount. The license is renewed every twelve months, and the statute sets the initial fee at $50.
• Commercial work. Under Miss. Code 31-3-1, contractors need a certificate of responsibility for public or private contracts of $50,000 or more, with exemptions that include residential buildings for 50 or fewer families and up to three stories. Board Rule 1.1(3)(b) lists Mechanical Work as one of the six major classifications for that certificate (checked October 8, 2026).

The dollar threshold that applies to remodelers does not apply to HVAC subcontractors on homes, which is the point a buyer placing residential HVAC requests in Mississippi should note. Technicians who handle refrigerants also need federal certification under EPA Section 608.

Mississippi counties by owner-occupied homes

Below are the ten Mississippi counties with the most owner-occupied homes and the utility gas and electric shares of those homes, from the ACS 5-year 2020-2024 county tables B25003 and B25117. The table is about the housing stock; it says nothing about where leads come from.

Jackson County is the most electric of the ten at 80.4%, followed by Lamar at 78.5% and Harrison at 71.7%. DeSoto and Madison are majority utility gas, at 61.0% and 60.0%, in the same county data (2020-2024 ACS). Propane is above 9% of owner homes in Rankin, Jones and Lauderdale.

What Mississippi HVAC buyers filter on

Mississippi HVAC buyers usually set four filters. Here is how the facts above relate to each:

• Project type: for example install, replace or repair, for heating or cooling. With cooling degree days at the 5th highest level in 2025, many buyers favor cooling work.
• Homeowner status: 801,788 owner-occupied homes, where replacement decisions sit (ACS 2020-2024, B25003).
• Timeframe: a homeowner with no cooling in August needs a visit within days; one comparing heat pumps can wait.
• ZIP code: buyers select ZIP codes their crews can reach, for example Jackson County ZIP codes for heat pump work or DeSoto County for gas furnaces.

When HVAC opens, Mississippi buyers will set these filters per campaign, down to the ZIP code, as on Summit’s other home services leads. Once HVAC opens, HVAC leads will be exclusive by default, with shared delivery on request. Every field is shown on the sample HVAC lead.
