We are a full service Air Conditioning and Heating Company. As we prove, "If we can't fix it, it can't be fixed!". We also offer regular rates all day long, this means NO OVERTIME (EVER)! However, we can only work on your air conditioner during the daylight hours. Now your furnace is different though. We can work on your furnace in the middle of the night in case of an emergency or frigid temperatures. Although we can fix just about everything, we also install both cooling and heating equipment. With over 20 years experience, no overtime, the best warranty in town, and the least expensive prices in town, why call anyone else? We also do hot water tank repair and replacement. Angie's List Members receive a $49 diagnostic and 10% off the repair with paid invoice onsite on repairs only. (Cannot combine with Senior Discount 10% on repairs only) http://www.cool225.com

"Perfect. On time on budget."

"I've been with Posigen for about 7 years now and have always paid my bills on time!!!! As of Feb. 2022, I haven't been able to monitor my Solar Production because Posigen haven't updated their system to 5g Capability!!! I told them my payments are to be deferred until they update the system on their end!!! I spoke with a couple Reps that said your panels are producing what they should based on your production on your Electric Bill!!! I asked how can I know if I cant see the daily production to ensure the panels are producing what they should!!! They said take my word for it!!! I'm like that's very bogus to tell a faithful customer to take your word!!! Especially when the issue is not on their end!!! Now because of Non-Payments for 2 months of me not knowing what I'm producing since Feb, they're now threatening to shut my system off!!! Who treats a customer like this when the issue is on their end!!! Especially when that customer has been making faithful payments up into them not upgrading the system on their end!!! Can someone please recommend A good lawyer to stop them from interfering with system!!! Again, the issue is not on my end!!! I need help!!!!"

Energy Efficiency Auditing questions, answered by experts

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

Depending on property size and audit scope, costs range from $200 to $600.

Provide utility bills and clear access to all areas of the home, including the attic and basement.
