FAQs
How do I know when itâs time to replace my HVAC unit in Deer Lodge?
Common signs include rising energy bills, uneven temperatures from room to room, frequent breakdowns or costly repairs, noises or odors coming from the equipment, and a system that is 12â15+ years old. A professional load calculation and inspection will confirm whether repair or replacement is more cost-effective.
What is the average cost of an HVAC replacement in Deer Lodge, and what factors affect the price?
Most full system replacements in Deer Lodge range from $6,500 to $12,000, depending on unit size (measured in tons or BTUs), efficiency ratings (SEER2 or AFUE), ductwork condition, desired indoor air-quality add-ons, and any electrical or code upgrades required. We provide a no-obligation on-site estimate so you know the exact price before any work begins.
How long does an HVAC replacement take from start to finish?
Once equipment is available, the typical residential change-out takes 1â2 business days. Day one is removal of the old system, setting the new unit, and connecting refrigerant lines, electrical, and condensate. Day two (if needed) covers duct adjustments, smart thermostat setup, and start-up testing. Larger homes or extensive duct modifications can add another day.
Will a new HVAC system really lower my utility bills?
Yes. Modern high-efficiency heat pumps, air conditioners, and furnaces can cut cooling and heating costs by 20â40% compared to units installed just 10â15 years ago. Features like variable-speed compressors, ECM blower motors, and smart thermostats reduce energy waste and keep indoor temperatures steadier, delivering noticeable monthly savings.
What types of warranties and guarantees do you provide on replacements?
We register every new system for a 10-year manufacturer parts warranty and include a 1-year labor warranty at no extra charge. Optional extended labor coverage up to 10 years is available. In addition, our Deer Lodge Comfort Guarantee states that if the new system does not perform as promised within the first two years, we will correct the issue at no cost or refund your investment.
Do you offer financing for HVAC replacements, and how does it work?
Yes. We partner with local and national lenders to offer multiple financing plans, including 0% APR options for up to 18 months and low fixed-rate terms up to 120 months. Applications take less than five minutes, require only soft credit checks, and most customers receive instant approval, allowing you to replace your HVAC system without delaying comfort.
