"My experience with Green City Heating and Air has been great from start to finish. First, Jeff, the owner, gave me various options for my heating and cooling needs and quickly followed up with a detailed written bid at a competitive price. He was also able to include some rerouting of ductwork and moving the position of my furnace for a more reasonable cost than the quotes I'd been given by the big HVAC companies. The HVAC techs -- Ron, Anthony, and Tyler -- were all professional, respectful of my home, really hard-working, and just nice guys to be around, and Debbie in the office has been so helpful and such a pleasure to deal with. Thank you, guys -- you're all awesome! But what impressed me most about Green City is how they reacted when we ran into a couple of unexpected problems: they were responsive, very fair, and worked on finding a solution I'd be happy with. This company seems to genuinely care about providing great customer service, and that's a rarity these days. I wouldn't hesitate to hire them again in the future and I'll be recommending them to all my friends and family."

"With freezing weather on the way, it was time (past time) for maintenance service on our 10-year-old gas furnace.  After much research on the List, I called Pacific Air Systems because of their positive reviews.  The office staff were cheerful and helpful, and they worked with us to get an appointment time that would disrupt our workday as little as possible.  Technician Nathan was perfectly on time.  He was friendly and professional, everything you would want in a technician (he was even very kind to my pet).  He explained up front what the maintenance service would include.  Fortunately, no problems were encountered.  One component was at the end of its useful life, and he gave me the option of replacing it now or waiting, and he explained the ramifications.  I played it safe and replaced the part while he was here.  When done, he explained the company's optional service contracts with absolutely no pressure to buy anything.  I did decide to purchase a one-year agreement just to avoid the hassle of trying to remember to schedule next year's maintenance appointment.  It's a good idea to have reliable service providers lined up for your plumbing, electrical, and HVAC needs in advance, and I feel very confident in Pacific Air Systems after this.

"Ranger did a great job. The estimators were friendly and thorough, the installers and team we encountered were all respectful and hard working. There was a problem with the electronics in the thermostat from the factory, they worked late and had to bring a new thermostat the next day, but the new one works perfectly. We will hire again for any other HVAC needs. We chose a higher quality AC unit and are glad we went with a quieter model, the unit is so quiet in the backyard."

"Received 4 quotes. Cummings was the least expensive that I used to bargain two others to. They matched but had install dates of 30 days. Cummings had their electricians and HVAC guys here in 8 days. Installation done in 4 hours. All had good customer service & tech skills."

"Post Results was very responsive when we reached out, asking very specific questions to help understand our project. They came out, provided a thorough analysis of both our existing HVAC ducting in our craw space and provided helpful input on the new section of HVAC ducting we needed installed. They provided a quote quickly at a fair price. They installed the system the day we were scheduled, and exceeded our expectations on cleanliness of the work area and quality of install. We would definitely recommend them to others."

Heating and Air Conditioning FAQs, answered by experts

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.

While both have advantages, a split system is generally cheaper than a ducted one. Because they are less invasive to install, the labor costs are lower, and they can be more energy efficient. But, a ducted system might be worth the investment if you run it more frequently. 

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

While all portable AC units will collect moisture as part of their cooling and dehumidifying process, whether and how often you need to drain them depends on what kind of unit you have and the natural humidity levels where you live. For example, if you live in a very dry area and have a self-evaporating unit, you may not need to drain your portable AC very often at all. Some units may automatically drain collected moisture out the window through their exhaust vent.
