"Replaced capacitor. Still didn't work, so we were looking at ac replacement. Before we did, technician continued to experiment by cooling of the compressor with the garden hose and it worked! Saved me thousands in replacement costs."

"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."

"We were experiencing problems with our central air conditioning unit. It was running, however, it did not cool the condo fast enough. The Four Seasons Technicians arrived on time, very professional, thorough explanation of what was wrong with the unit, and provided solutions on how to fix the unit. He was very helpful in helping me negotiate for a new coil and A/C unit. He was dressed in protective covering during COIVD-19. I would use Four Seasons Heating & Air Conditioning again. I was very happy with their service."

Air Conditioning questions, answered by experts

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

A dirty air conditioning coil can cause your unit to work overtime, leading to reduced efficiency, higher energy use, more wear and tear, and possible ice buildup. If the coils corrode, refrigerant can leak, causing damage, possible mold growth, and an expensive repair bill. By cleaning your AC coils once a year, you’ll have a more efficient unit that’s likely to last longer.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

Assessing location for airflow, convenience, and minimal noise impact.

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).
