We at Allred Heating, Cooling and Electrical hope to become your trusted friends and partners in keeping your homes safe, comfortable, and a pleasant environment for you and your families. How Allred Got Started Our company was founded by Dan and Matt who discovered they had complimentary areas of expertise. Matt began as an electrician about a decade ago and besides doing electrical work began working with HVAC as well. Dan had been doing contractor work in Alaska and when they met they realized they were a perfect match to begin a business, hence Allred Heating, and Cooling and Electrical. Between the two of them all of the right bases were covered to offer complete electrical and HVAC systems, both installation and repair. Allred Heating Family Hopes to Help Your Family We are a family owned company and we know how important it is to keep our homes working economically and safely. We hold ourselves and our work to the highest standards and that is why we offer a one year parts and labor guarantee. We are bonded, licensed and insured to and we’d like to show you why you can have the utmost confidence in us. We will give you upfront estimates so you’ll know what your bottom line will be.

"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"

"I requested an HVAC service call quote from G&S Heating through Angi, and received a "deal" via Angi for $129. I chose them partly due to that price. G&S Heating ended up billing me $280, and said that was an old outdated deal and would not honor it. Irresponsible and incredibly poor customer relations. Also, the technician they sent did not seem very knowledgeable or experienced. He said the thermostat reading issue I was having would require another service call and the possible replacement of an expensive circuit board. I ended up fixing the problem myself. I will not be using G&S Heating again."

For 45 years we’ve been making Puget Sound homes the most healthy, energy efficient and comfortable homes in the country. Our experienced team brings decades of expertise installing and maintaining the most innovative and efficient technology. As a Mitsibushi Cooling and Heating Diamond Contractor, Evergreen Home Heating and Energy has some of the world's most efficient and innovative products available.

"We had Evergreen Home Heating and Energy install a new water heater and furnace, and unfortunately, the quality of their work has been disappointing. Recently, I noticed several issues with the intake and exhaust pipes. Several hanger straps attached to the wall are broken, and one of the joints on the water heater exhaust pipe is leaking water. I suspect this leak is caused by the imbalance due to the broken hanger straps. I expected a professional and reliable installation from Evergreen Home Heating and Energy, but these problems indicate a lack of attention to detail and quality. Based on my experience, I cannot recommend Evergreen Home Heating and Energy. If you’re considering them for your home needs, be cautious and perhaps look elsewhere."

"We went with Greenwood because we heard that they would take care of us, even though they were more expensive. We had a great experience with the first walkthrough with a knowledgable expert, but every interaction since has been poor. We had several issues with the installation; they had to come back several times. Five years later, the water pump with the furnace broke and they take care of it, but it costs $900. They take care of us, but continue to be expensive. I highly recommend avoiding this company and finding a business that knows what their doing and where all technicians care about the customer."

FAQs for central humidifier installation and replacement projects in Magnolia, 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.
