Make permit responsibility part of the quote

Mecklenburg County's residential guidance includes the addition, replacement or redesign of heating and air-conditioning systems among work requiring permits. Ask each company to explain the permit and inspection work for your project and include its responsibility in the proposal.

That keeps an equipment price from being mistaken for the complete installed scope. A proposal should make clear which work is included and what remains to be confirmed. This guidance applies within Mecklenburg County; a Charlotte-area search can also return companies serving other counties with different permitting authorities.

Check the company named on the proposal

North Carolina's State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors provides a public license search. You can search by company name or license number and narrow the search by classification.

Ask for the name and number behind the quote, then compare them with the official record before choosing an installer. If the proposal names a different business, have the company explain that difference. Use the exact company details for this check, and ask the company or board to clarify anything you cannot match.

Confirm current HEAR rules before counting an incentive

If a proposal includes an Energy Saver NC HEAR rebate, ask which current requirements apply to your project. NC DEQ changed this pathway from September 1, 2026 for applications that had not reached rebate reservation status.

The update allows electric-to-electric upgrades and says insulation or air sealing may be required with a heat-pump project. It also excludes replacement of fossil-fuel appliances through HEAR. These are rules for that specific pathway, not every North Carolina incentive. Keep the full installed price visible and ask the program to confirm eligibility before treating any rebate as part of your budget.

Compare the proposed heating arrangement

In the Census Bureau’s 2020–2024 survey estimates for Charlotte, about 44% of occupied housing units used utility gas as their main heating fuel and about 54% used electricity. These citywide estimates include rental homes and have sampling uncertainty. Electricity does not identify a particular type of heating equipment.

Start with the fuel and model on your own system. If one proposal keeps that arrangement and another changes it, ask each company to separate retained equipment, removal, new equipment and any proposed electrical or gas work. That makes the difference in scope easier to compare.

Make the quote fit your property

The 2020–2024 Census survey estimates put about 51% of Charlotte’s housing units in detached one-unit homes and about 38% in buildings with two or more units. These approximate figures include occupied and vacant units. They do not show whether a particular home has shared heating or cooling equipment.

Describe your actual property, the rooms served and access to the equipment. If a system or outdoor space is shared, ask who can authorize the proposed work. Have each company state which equipment and spaces its quote covers, so you can compare the same project.
