We serve Minneapolis & St Paul as well as the surrounding suburbs. We manage Pronto from a local office & we are committed to providing friendly, hassle-free service and employing only the best technicians. You may recognize us from another local air conditioning company. The Sedgwick family sold its business in 1999 to a national manufacturer and Wade and Greg stayed on to run the business from 1999 through March 2008. We opened Pronto because we felt we could provide a personalized experience and exceptional customer service by managing our entire business from a local office. We are committed to providing friendly, hassle-free service and employing only the best technicians. Pronto is proud to have won the Bryant 2009 Dealer of the Year award. The award is given each year to Bryant’s best dealer out of more than 4,000 dealers in North America.

"Customer service: excellent. Technical knowledge: excellent. Explaining complex systems to a senior: couldn't have been better. You really get the sense that this company has it's act together. These guys deserve the five stars I gave them. Gregg, Roseville"

We have been proudly serving the twin cities since 1947, we strive to deliver the best customer experience possible with our fast, friendly and honest service!!! We offer 24/7 service 365 days a year!! We know what it takes to get the job done and to do it well.

You may also see our billboards all over the twin cities, just look for the orange & teal offers!!! Call us today and I guarantee you won't go wrong.

"Hoffman came out to check my furnace after it wasn't keeping up with the cold snap. Unfortunately, the heat exchanger was rusted, but we were able to schedule a replacement for 2 days later. I ended up with a new Lennox furnace/heat pump combo and had heat a few hours later that day. I did have some installation issues that were resolved a couple of days later. I had a lingering issue with a faulty humidistat on the thermostat, so the humidifier wasn't running. This was due to a bad batch of thermostats, but it was finally resolved on the fourth visit several weeks later. Overall, Hoffman was very easy to deal with, and they didn't ghost me after my check cleared. Communication was good. Although I would have rather had everything done correctly on the first visit, these things happen and I am happy with the end result. "

FAQs for window a/c unit service or relocation projects in Castle-rock, MN

If your window air conditioner is relatively new or of high quality, repairing it can restore optimal performance and protect your investment. However, for older units or those with ongoing issues, it might be more cost-effective to replace the unit to ensure long-term efficiency and reliability. Consider the unit's age, the severity of the problem, repair costs versus replacement, and energy efficiency ratings when making your decision. If repairs cost more than half the price of a new unit, replacement is typically the better option.

Window air conditioners last eight to ten years on average. After this time, you may notice decreased efficiency and component wear. Replacing an older unit can improve energy savings and provide updated features like remote controls and better overall performance. With proper maintenance including regular filter cleaning, coil checks, and professional servicing, you can maximize your unit's lifespan.

If your portable AC isn't cooling, it might have a refrigerant leak or a circuit malfunction that's preventing it from working properly. It's best to contact a local air conditioner contractor to inspect and repair the unit. If your AC is older and repairs don't fix the issue, replacing it might be the most effective solution.

Removing a wall-mounted AC costs $55 to $75. Completing the removal yourself at the end of each summer season, being sure to do so according to proper guidelines, keeps you within this cost range. Should you require professional assistance for removal and disposal, if you can't move the unit yourself, expect an added fee of $25 to $50 to the overall cost.
