"I bought a new (old) house in Brookfield and the air conditioner unit promptly failed. I got bids from three contractors I found via Angie's List. Not only did Jim at Vent give me the most competitive bid, he was hands down the most responsive to questions and phone calls, gave the most thorough inspection, and ended almost every conversation with a very sincere, "let me know if there's anything more I can do to win your business." On install day, his guys were early and ready to work. Jim showed up shortly after to supervise. My wife was there that day and he explained everything they were doing and why. He had budgeted 2-4 hours to do the job, but the previous install had been done so poorly that there was a lot of stuff they needed to fix so the new air conditioner was installed to their satisfaction, so they were there for more than 6 hours and didn't ask for a dime more than their quote. I couldn't recommend these guys more highly."

Air Conditioning questions, answered by experts

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

After a while, dust, dirt, and other debris accumulates on an AC unit's coils and filters, making it less efficient and spreading allergens and other air pollutants throughout your home. Cleaning your AC unit will keep it running efficiently, minimizing future breakdowns and improving your indoor air quality.

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

Florida rooms can have heat or air conditioning, although not all do. These rooms can be added to the existing HVAC system or use a mini-split system, or they may just use a ceiling fan or the breeze from the windows for cooling. Florida rooms with air conditioning often have glass windows to keep the cool inside instead of just mesh screens.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.
