FAQs
How can I tell whether I should replace my HVAC unit instead of repairing it?
Several signs indicate it may be more cost-effective to replace rather than repair: (1) Age—systems over 12–15 years old are nearing the end of their service life in Johnson City’s humid summers and cold winters. (2) Frequent breakdowns—if you have faced two or more major repairs in the last two years, replacement typically saves money long-term. (3) Rising energy bills—older equipment loses efficiency; a new high-SEER/AFUE unit can cut operating costs by 20–40 %. (4) Outdated refrigerant—systems using R-22 refrigerant are expensive to service. (5) Comfort issues—rooms that are always too hot or cold suggest the system is improperly sized or worn out. Our technicians will perform a full evaluation and provide a repair-vs-replace cost comparison so you can make an informed decision.
Which HVAC brands and system types do you install in the Johnson City area?
Lasting Reliability Heating & Air Conditioning is an authorized dealer for industry-leading brands such as Trane, Rheem, Goodman, Mitsubishi Electric, and American Standard. We offer: high-efficiency split heat pumps, gas furnaces with matching air conditioners, dual-fuel hybrid systems, variable-speed inverter units, and ductless mini-splits for room-by-room zoning. All equipment we recommend is certified by ENERGY STAR and engineered to handle Northeast Tennessee’s temperature swings and humidity levels.
What happens during a typical HVAC unit replacement, and how long will it take?
Most residential replacements are completed in one day. Here is the usual timeline: 1) Pre-job load calculation and system selection. 2) Arrival between 8–9 a.m.; we lay down floor protection and isolate the work area. 3) Safe removal and environmentally responsible disposal of the old unit and refrigerant. 4) Installation of the new indoor and outdoor sections, line-set, drain, and thermostat. 5) Pressure testing, vacuum, and factory-specified refrigerant charge. 6) Commissioning tests for airflow, static pressure, and temperature split. 7) Customer walk-through for thermostat training and warranty registration. Larger homes or add-on ductwork can extend the project to two days, but we will give you a precise schedule before we start.
What warranties and guarantees come with my new HVAC system?
All new systems we install include a 10-year manufacturer’s limited parts warranty and up to a 10-year compressor warranty when registered within 60 days. Our company adds a 2-year labor warranty at no additional cost, plus a Lifetime Craftsmanship Guarantee on our installation work. Optional extended labor coverage (up to 10 years) and annual maintenance agreements are available for added peace of mind.
Are there energy rebates, tax credits, or financing options for HVAC replacement in Johnson City?
Yes. TVA’s EnergyRight program offers rebates—typically $150–400—on qualifying high-efficiency heat pumps and dual-fuel systems. Federal tax credits under the Inflation Reduction Act provide up to $2,000 for heat pumps meeting CEE Tier 2 efficiency standards. Johnson City Power Board customers may qualify for low-interest utility financing that can be paid on your monthly bill. We partner with Synchrony and Wells Fargo to offer 0 % APR plans for 12–18 months, subject to credit approval. Our office will handle the paperwork and apply all available incentives to lower your out-of-pocket cost.
How do you ensure the new unit is correctly sized for my home?
Proper sizing is crucial for comfort, efficiency, and long-term reliability. We perform an ACCA Manual J heat-load and cooling-load calculation that factors in square footage, insulation levels, window orientation, air leakage, and occupancy. We also evaluate existing ductwork with Manual D to verify it can deliver the required airflow. This engineering approach prevents oversizing (which causes short-cycling and humidity problems) and undersizing (which leaves rooms uncomfortable on extreme weather days). Once the data confirms the correct capacity, we present model options that best match your home’s needs and budget.
