"Ruben and the team did such a great job on the first project (2-3yrs ago) that I asked them to come back and finish my condo's water heater closet, which showed wear and tear from past water damage. They did a fantastic job in repairing the closet and adjacent living room's dry walls that it looked seamless to the rest of the unit. The team was always conscious of keeping the work area clean as they closed the area off with tarp and placed drop cloths down. I greatly appreciate the amount of high-quality work done in a short time span, especially when asked within two weeks of the project starting. I've recommended the team to my family and friends if they ever need a job done right by a team who is professional, courteous, and knowledgeable."

"Courteous, Professional, and Knowledgeable HVAC Installer - Needed to replace a 25+ year old HVAC system in the coldest months of the year and SwiftPro was the right choice. I live in a condo with a tricky indoor/outdoor HVAC set-up. Tyler worked with me to ensure I had the right system that 'fit' in the area left after removing the old system. Workers were completely professional and knowledgeable during installation and dare I say - courteous. Installation was supposed to be same-day, but one part was unavailable at the time. Tyler and his staff hunted across the local area for the part and even sent an employee out to buy a space heater to spare me from the below-20 degree night. Part came in next day and installation was complete. Very satisfied with the outcome of the project."

"I have been a customer for a very long time and this scheduled maintenance and dryer vent cleaning was done by Cesar. I have to say he is one very thorough technician and I was very pleased with his inspection and vent cleaning. His service was so different than some of the ones I've had before. I even had one inspector tell me he didn't need to check in my attic which houses one of our two units. Let me tell you about Cesar, he even cleaned up behind my dryer for me. This is something that is rare in customer service. I have my HVAC seasonally maintenanced and never had a inspector be as thorough as him. The pictures he took and explained to me and the one problem he found that no other inspector had found in all this time. I tried to spare him from the attic heat for the repair and have him return on another day in the morning but he didn't mind going back in there to fix the problem for us although it was in the dead heat of the day. I just hope the company sees this review and knows what a good technician they have in Cesar."

"Snell installed our new HVAC and we were initially pleased. However, the unit failed a county inspection. When Snell reached out to set up a repair, our window was 10am-2pm. The technician showed up at 4pm without the materials he needed. He promptly left having done nothing, said he would get what he needed and return. We heard nothing."

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.
