Frequently Asked Questions

The warranty covers both replacement parts and technician labor for Tempstar heating and cooling systems installed by DLM Enterprises. Most manufacturers cover parts only, requiring you to pay separately for service calls and installation of covered components. This complete coverage protects against both equipment failure costs and repair labor expenses for a full decade.

Schedule furnace maintenance in fall before heating season begins and air conditioning service in spring before cooling demand starts. Florence's humid summers and freezing winters create distinct seasonal loads that stress different system components. Catching refrigerant leaks, worn belts, or failing capacitors before peak usage prevents breakdowns during temperature extremes.

Dust and debris accumulation restricts airflow through supply and return vents, forcing the system to work harder to circulate conditioned air. Cleaning removes obstructions that reduce airflow by up to 30 percent in neglected systems. You'll notice more consistent temperatures between rooms and shorter heating or cooling cycles after duct cleaning.

Central systems use ductwork to distribute cooled air throughout the entire home from one indoor unit, while mini splits provide ductless cooling to individual rooms or zones using separate wall-mounted units. Mini splits work well for additions, older homes without existing ducts, or areas needing independent temperature control. Central air costs less for whole-home cooling when ductwork already exists.

Commercial cooking generates grease-laden vapor, smoke, and combustion byproducts that exhaust hoods capture and vent outside the building. Without proper hood ventilation, grease accumulates on surfaces creating fire hazards while smoke and odors contaminate dining areas. Hood systems include fans, ductwork, and grease filters sized specifically for the cooking equipment's heat and vapor output.

Refrigerant leaks, failed capacitors, broken blower motors, and electrical component failures cause sudden system shutdowns. Skipping seasonal maintenance allows minor issues like dirty coils or loose wiring to escalate into complete failures. Most emergency calls happen during the first hot or cold day when neglected systems can't handle the sudden demand.

Ductwork showing rust holes, separated joints in multiple locations, crushed sections, or asbestos-wrapped insulation typically needs full replacement. Disconnected joints or small holes can be sealed, but widespread deterioration means the entire system is failing. Ducts over 25 years old in unconditioned spaces like attics often have multiple failure points making replacement more cost-effective than patching.

Technicians inspect and clean coils, check refrigerant charge, test capacitors and contactors, measure airflow, examine electrical connections, and replace filters during maintenance visits. Each component affects efficiency and lifespan differently—low refrigerant reduces cooling capacity while dirty coils force longer run times. These checks catch developing problems before they cause complete system failure.

If your furnace is over 15 years old and needs heat exchanger, blower motor, or gas valve replacement, the repair cost often exceeds 50 percent of new equipment pricing. Older furnaces also operate at 60-80 percent efficiency compared to 95-98 percent for new models. Calculate whether repair costs plus continued high energy bills exceed replacement investment within three years.

Airflow improves throughout the workspace, removing heat, odors, fumes, and airborne contaminants that accumulate without adequate ventilation. Employees notice reduced stuffiness and temperature drops in areas with heat-generating equipment. Properly sized exhaust fans create negative pressure that prevents contaminated air from spreading to adjacent spaces.

Returning technicians remember your system's history, previous repairs, and recurring issues without reviewing notes from scratch. They notice gradual changes like declining airflow or increasing noise that indicate developing problems. Familiarity with your specific equipment speeds diagnosis and helps technicians spot patterns that one-time service calls miss completely.
