Between the two of them all of the right bases were covered to offer complete electrical and HVAC systems, both installation and repair.

"Best Customer Experience even if I chose another Contractors Hardware: Dave Rolig that came out to do the estimate was very knowledgeable and took the time to know me and answer any and all of my questions. His experience and genuine caring were unmatched! An employee to make any company very proud. He even offered to meet price of competitors product. In the end it was my engineering analysis of the hardware choices that had me chose the competitor. And that was nothing he could overcome. He gave me every reason to believe Allred was only selling a product they believed in and would fully stand behind for many years to come. I would highly recommend Allred Heating Cooling Electric and Dave Rolig to anyone shopping for these services! Thank you for your prompt and complete support through this experience. Brian Garber"

"They didn't seem interested in repairing my furnace. All they wanted to do was sell me a new furnace. The demeanor of the technician, Nicholas, changed to argumentative and belligerent when I said I was not buying a new furnace. When I tried to complain to the manager, he became argumentative as well. He did return the diagnostic fee after I told him I was getting a 2nd opinion."

FAQs for central humidifier installation and replacement projects in Olympia, WA

Aim for indoor humidity between 30% and 50%, with the sweet spot around 45%. That range keeps mold, dust mites, and musty odors in check while protecting drywall and woodwork. Staying in the zone also helps your HVAC system run more efficiently and supports healthier air for you and your family year-round, during hot summers and cold winter months.

With routine filter changes and coil cleanings, most whole-house units run for eight to 15 years. Heavy use, poor air quality, or bargain-bin equipment can shorten that span, while a well-maintained, high-quality model often makes it to the upper end of the range. Ask your installer about recommended service intervals to get the most mileage from your investment.

It depends on your climate. Homes in cold, dry regions can often shut the dehumidifier off once winter sets in. If you live in a warm, humid area—or your house tends to trap moisture—you may need to keep it running year-round. Use a simple hygrometer: if readings stay below 50%, give the unit a rest. Just remember to restart it when humidity climbs again to avoid mold and condensation.

Dry air feels cooler, so your AC doesn’t have to work as hard. By stripping out excess moisture, the dehumidifier lets you raise the thermostat a few degrees without losing comfort. A shorter AC runtime reduces electricity use and can shave a noticeable amount off your summer power bill. Energy-efficient models further enhance those savings.

If your home is under about 2,000 square feet, a well-placed portable unit can handle the load. Just remember they’re less efficient and need hands-on upkeep—think emptying tanks and cleaning filters. If you prefer set-and-forget convenience or plan to expand your living space, a whole-house model still offers better long-term comfort and lower energy use per square foot.
