"I've participated in Standard Heating &Air Conditioning for many years. The come out promptly twice a year to check the AC in the spring Furnace in the fall. Scheduling is easy, they arrive on time, they are courteous and efficient. They always explain their recommendations and pricing and provide options. Ben came out this fall and displayed all of the qualities I've come to expect from Standard Heating and Air Conditioning techs."

"Speed, accuracy, vast knowledge of air conditioners that give most value in MN vs southern US. 18 year old AC died on a Sunday, replaced in 4 hours next day. Unbelievably fast response for full AC replacement in mid-summer."

"A great experience from a terrific team. After we were told by our (now past) HVAC company that we needed a new furnace, I called Design by Comfort for a second opinion. When I called their office, the woman I spoke to understood my situation immediately and had their team on my doorstep at 8:00 the next morning, on the dot as scheduled. Their service specialist took apart the furnace inspected it and showed me by video the heat exchanger that our original contractor told me was bad.
Based on his very thorough examination, we knew that the furnace did not need replacement.
Obviously, the first company did not tell us the truth about the condition of our furnace so as to sell us a new one even though it was not needed.
The Design by Comfort team was honest, professional, and highly responsive. They saved me thousands of dollars. When the time comes, and it always does, for us to get a new furnace, they will certainly get our business.

"I hired this company for air duct cleaning and couldn’t be happier with the experience. From scheduling to completion, everything was professional and straightforward. The technicians arrived on time, explained the entire process, and used powerful equipment to thoroughly clean our vents and HVAC system. We immediately noticed improved air quality and less dust in the house. They were respectful of our home, protected the work areas, and cleaned up completely before leaving. What really stood out to me was their professionalism and honesty. They did NOT nickel and dime me, their pricing was extremely competitive, and they didn’t try to push a bunch of additional services I didn’t need. They simply explained what they offered, answered my questions, and gave me exactly what I needed. I truly appreciated that approach. If you’re looking for reliable, high-quality duct cleaning with fair pricing and no pressure, I would absolutely recommend them. Great service and great results!"

Air Conditioning questions, answered by experts

To find a reputable HVAC company, start by researching providers in your area. Look for companies with mostly positive online reviews and check the Better Business Bureau’s website for customer complaints. Next, verify their credentials. Rule out any companies that aren’t licensed, as this is a requirement in some states and municipalities, and confirm they are insured. Once you have a shortlist, contact each professional to ask key questions: How many years of experience do you have? Do you hold any third-party certifications? Do you have experience working on my specific type of HVAC system or brand? Can you provide references? What is your per-hour pricing? Do you offer maintenance contracts for ongoing savings? Do you provide a warranty for your work?

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.

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma. 

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

To diagnose a bad HVAC or AC damper, assess the airflow from your vents. For a manual damper, close it, run your system, and check for airflow. If air is still coming through the vents, the damper is likely faulty and needs repair or replacement. For an automatic damper, turn on your HVAC system and monitor the airflow and room temperature. Signs of a problem include low airflow, a room that won't maintain its set temperature, or a drafty feeling. If you suspect a faulty automatic damper, you may need to hire a professional for repairs.
