"Very pleased with this contractor and the cost and quality of their work. Upgraded my panel to 200 Amp service, split an overloaded circuit, and ran a line set for an HVAC project. Max and his team are real pros. The cost estimate was fair and accurate. After initial review of the project, we made a few changes on job day, and these were accomplished with zero problems. Their coordination with the electric co-op was also flawless and the job was accomplished on time and within the cost estimate. They even gave me a $100 credit for the removed 100 Amp panel. I plan to hire them again to wire an existing out building on my property. If you need electrical work, call them!"

My mother's air conditioning unit was about 20 years old and for the past 2 - 3 summers, she had had problems with the air going out. She used a warranty company but this time they wouldn't help saying she had had someone outside of the company work on her unit (which she hadn't). After many calls and conversations, she realized they would not help. She called me (my mother lives in St. Louis, but I live out of state) asking for assistance. I went online and called several companies, it was close to the holiday weekend and no one wanted to come out and to give a quote until the following week - after the 4th of July! My last call was to Manson's Heating & Cooling. They answered the call promptly - I didn't have to go through a series of prompts and button pushing to speak with someone, and they agreed to come out that same day. When the technician arrived (Kim), he checked everything out and stated her unit was basically worn out and did need to be replaced (which is what the two companies through the warranty company said also). At this point her air had been out for about two weeks with the temperatures in the 90's and she was desperate. He quoted her a very reasonable price, and she called to have me speak with the technician. He was very straight forward and explained to me what was going on with her unit, and why it needed to be replaced. I explained that I would be paying for the unit to be replaced, but that I lived out of state and could not get the funds to my mother's account until that Thursday or Friday. We were able to work out a deal over the phone that was comfortable for each of us and God Bless him, he put her unit in the next day!

I called her back that Tuesday and she was so happy to have them there putting in her new unit. She stated they were so nice and respectful. They arrived around 8 am that morning and everything was completed by early afternoon. She has had no further problems with her air and hopefully it will remain that way long into the future. But if something does happen, our first call will be to Manson's Heating & Cooling!

Heating and Air Conditioning FAQs, answered by experts

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation. 

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.

Not if you have a standard unit. Because portable AC units actually work to dehumidify the room, you’ll likely need to drain the unit from time to time—but you won’t have to put water into it. There is, however, another type of air conditioner called a swamp cooler that requires water to operate. If you have a swamp cooler, you may need to fill a reservoir with water and potentially ice. But a swamp cooler is different from a standard portable AC unit.
