SEER Rating

HVAC

SEER (Seasonal Energy Efficiency Ratio) is a measure of an air conditioning system's cooling efficiency over a typical cooling season. Higher SEER ratings indicate greater energy efficiency. As of 2023, the minimum SEER rating for new residential AC units is SEER2 14.3 in the northern United States and SEER2 15.2 in the southern United States.

Heat Pump

HVAC

A heat pump is an HVAC system that transfers heat between indoor and outdoor environments. In winter, it extracts heat from outdoor air and moves it inside. In summer, it reverses the process to cool the home. Heat pumps are energy-efficient alternatives to traditional furnace and AC combinations.

Electrical Panel

Electrical

An electrical panel (also called a breaker box or load center) is the main distribution point for electrical circuits in a home. It receives power from the utility company and distributes it to individual circuits. Panel upgrades are common when homes need more electrical capacity for modern appliances, EV chargers, or solar installations.

GFCI Outlet

Electrical

A GFCI (Ground Fault Circuit Interrupter) outlet is a safety device that quickly shuts off power when it detects a ground fault or current leak. GFCI outlets are required by code in wet areas such as kitchens, bathrooms, garages, and outdoor locations. They help prevent electrical shock.

Roofing Square

Roofing

A roofing square is a unit of measurement equal to 100 square feet of roof area. Roofing contractors use squares to estimate materials and labor costs. For example, a 2,000-square-foot roof equals 20 roofing squares.

Asphalt Shingles

Roofing

Asphalt shingles are the most common residential roofing material in the United States. They consist of a fiberglass or organic mat coated with asphalt and topped with mineral granules. Asphalt shingles typically last 20 to 30 years and are available in a wide range of colors and styles.

Solar Panel System

Solar

A solar panel system (also called a photovoltaic or PV system) converts sunlight into electricity for residential use. A typical residential solar installation includes solar panels, an inverter, mounting hardware, and a monitoring system. Solar panels can reduce or eliminate electricity bills and may qualify for federal and state tax credits.

Net Metering

Solar

Net metering is a billing arrangement that allows homeowners with solar panels to send excess electricity back to the grid in exchange for credits on their utility bill. When the solar system produces more power than the home uses, the meter effectively runs backward. Net metering policies vary by state and utility company.

Foundation Repair

Foundation

Foundation repair is the process of fixing structural issues in a building's foundation. Common signs that foundation repair is needed include cracks in walls or floors, doors and windows that stick, uneven floors, and gaps between walls and ceilings. Professional repair methods include piering, slabjacking, and wall anchoring.

Pier and Beam Foundation

Foundation

A pier and beam foundation elevates a home above the ground using concrete piers and wooden beams. This type of foundation provides a crawl space underneath the home, making plumbing and electrical work more accessible. Pier and beam foundations are common in older homes and areas with expansive clay soils.

Integrated Pest Management (IPM)

Pest Control

Integrated Pest Management (IPM) is an environmentally sensitive approach to pest control that combines biological, cultural, physical, and chemical methods to minimize health and environmental risks. IPM focuses on long-term prevention rather than just treating symptoms.

Curb Appeal

Landscaping

Curb appeal refers to the visual attractiveness of a home as seen from the street. Improving curb appeal through landscaping, painting, and exterior maintenance can increase property value and make a home more inviting. Professional landscaping and painting services are key contributors to curb appeal.

R-Value

HVAC

R-value is a measure of a material's resistance to heat flow. Higher R-values indicate better insulating properties. Proper insulation with appropriate R-values helps maintain comfortable indoor temperatures and reduces energy costs. R-value requirements vary by climate zone — Missouri and Illinois typically require R-38 to R-60 in attics.

Warm Referral

General

A warm referral is a recommendation from a trusted source who has personal experience with the service provider. Unlike cold leads from advertising or lead generation platforms, warm referrals carry built-in trust. Little Lantern's entire model is built on warm referrals — homeowners receive recommendations from people who have already worked with and trust the contractor.
