FAQs
Why should I add a whole-home dehumidifier if my air conditioner already removes moisture?
Air conditioners do remove some humidity, but they are designed primarily for temperature control and cycle off once the thermostat is satisfied. In Coalmont’s long, humid summers the AC often shuts off before enough moisture is pulled from the air, leaving indoor relative humidity above the recommended 45-50 %. A dedicated dehumidifier senses humidity directly and continues to run as needed, preventing that sticky feeling, discouraging mold growth, and allowing you to set the thermostat a few degrees higher without sacrificing comfort—often lowering overall cooling costs.
How is a dehumidifier integrated with my existing HVAC system?
We install the dehumidifier in the return-air side of your ductwork or in a parallel bypass configuration. Humid air is drawn through the dehumidifier, moisture condenses on its coil, and the dried air is delivered back into the supply plenum so it’s distributed evenly throughout the home. A dedicated condensate drain line or pump removes the collected water. The unit is wired to its own humidistat or can tie into certain smart thermostats, letting it operate independently from the AC while still using the same ductwork and blower.
What capacity dehumidifier does a typical Coalmont home need?
Sizing depends on square footage, number of occupants, basement or crawl-space conditions, and the home’s air-tightness. As a rule of thumb, a 2,000-3,000 ft² home in our climate usually needs a 70-100 pint-per-day unit; larger or leakier homes may require 120 pints or more. During a free in-home assessment we measure indoor RH, check infiltration points, and run a Manual J moisture load calculation to recommend the right size so the unit is neither undersized (runs constantly) nor oversized (short-cycles and wastes energy).
Will running a whole-home dehumidifier raise my energy bills?
A dehumidifier does consume electricity—typically 3–6¢ per hour of run time—but it can reduce overall energy use by allowing the AC to run less frequently and at a higher temperature setting. Every degree you raise the thermostat saves about 3 % on cooling costs. Many homeowners in Coalmont see little to no net increase, and some notice a small decrease in summer utility bills because the AC isn’t over-cooling the house to control humidity.
How much maintenance is required once it’s installed?
Maintenance is straightforward. 1) Replace or clean the dehumidifier’s air filter every 3–6 months (more often if you have pets or live near dusty worksites). 2) Inspect and flush the condensate drain line annually to prevent clogs and overflow. 3) During your spring or fall HVAC tune-up, we’ll clean the dehumidifier coil and verify refrigerant pressures, electrical connections, and humidistat calibration. With proper care, quality units last 8–12 years.
How long does installation take and will it disrupt my home?
Most whole-home dehumidifier installations in Coalmont are completed in one visit lasting about 4–6 hours. We begin by isolating power to the HVAC system, cutting and fitting duct transitions, mounting the unit (often in the crawl space, utility room, or basement), and running the drain and control wiring. All work is done in mechanical areas, so there is minimal disruption—no wall demolition or painting required. After a full operational test, we explain the controls and maintenance steps before we leave.
