Providing quality service for the past 22 years, Aire Serv is your single source for heating and air conditioning. We look forward to helping you!

"Our A/C went out and Aire Serv was quick to schedule and identify the problem that required us to replace the unit. They came back the very next day for the install and did great work! They even re-routed some of our pipes for easier access rather than leaving them where they were. It seemed a bit expensive to me at first, but worth it for the quality and service in the long run."

"These guys are absolutely awesome! We had a cracked heat exchanger and it was dangerous to continue heating because of carbon monoxide leaking. The original duct work was all done incorrectly and caused the furnace (and A/C} to overwork. We had their representative, Danny come to our house one afternoon to give us a bid for heating, duct replacement, and air conditioning. Well, by the next morning we had we had a whole team of guys here and ready to start work on the job. I still don't know how they managed to pull it all together so fast!

Whether it’s an emergency repair, routine maintenance, or a new system installation, you can rely on us to deliver expert service with integrity, every time.

"WARNING - make sure you get a fully price estimate up front before they begin to do work. I brought them in to work on furnace/AC unit/split AC unit servicing garage (based on a promotional price for the first two). It was found my split unit needed a recharge for coolant and I was told that it'd only be 5 lbs of coolant and that this would be priced by the pound (which was reasonable). The bill came and they tacked on a flat charge of $219 for the coolant (this is in addition to the $129 charge to look over the split unit). I felt baited-and-switched. I also contacted them about this, and the answer came down to "This is additional profit for us added onto your bill." Not pleased. At all. Particularly since the coolant in question costs approximately $6 per pound and they only used 5 lbs (one would assume that the $129 charge built in enough profit for labor/licenses/equipment due to the limited time spent working on the split unit. Apparently not). Comfort By Design does excellent work, and they do stand by their work, but just be VERY CAREFUL in finding out what they're going to charge you, particularly if something extra comes up when they're doing a job."

Central humidifier installations and replacements FAQs

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.
