"Mario was quick to come out and assess the work needed, was able to schedule me in very soon, and did a thorough job installing the extra outlets. Was very pleasant (and so was Amber, the receptionist!) and I will be hiring Allied again for my electrical work."

"Brian is the owner-operator of the business and was right on time arriving at an easily scheduled time. He not only cleaned the dryer vent but also cleaned and disinfected all the furnace/air conditioning vents in our entire house. He did the work efficiently, kept us apprised of what things he was finding in the vents, was considerate of noise and hose & ladder hazards, and installed new filters in the return vents. I would highly recommend him to everyone who might need these services. As far as price & value, I found that his thoroughness and efficiency accompanied by his personable demeanor left me confident in his work and was well worth the price!"

"After a ghastly quote for repair from another outfit caused me to get a 2nd opinion, I'm so glad to have found ac medic on Home Advisor!!! Bob fixed our problem for less than 1/10 the cost of the other co.(which also turned out to have lied about the problem). I learned a lesson about "coupon" deals! Big markup on the part (although it did include labor), but service fee was waived since there was a repair involved. We'll definitely refer this co. to everyone!!!"

Air Conditioning questions, answered by experts

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.

A power outage can damage your air conditioner, just like a power surge can damage any electrical device or appliance. In most cases, your circuit breaker or built-in surge protection on your AC unit protects your AC and just needs a reset. But in other cases, it might be that your AC compressor or capacitor was blown during the power surge. You’ll need to have an HVAC professional repair or replace any AC parts. 

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.
