"They are excellent. I am a truck driver and not home very much. I needed my pipes winterized so they wouldn't freeze. The antifreeze is non-toxic. They drained my hot water heaters, put the antifreeze in. He turned off the water and made sure that it was winterized. I could turn the heat off. I thought it was high until, I realized they used two cases of antifreeze, and it is expensive. They were professional, courteous, and no issues. The price was good. I have no complaints with anything they did. I had to make an appointment, because they are busy. It took a while for them to come out on time and they showed up on time. Everything was good. They provided a good quality service at a reasonable price."

Heating and Air Conditioning questions, answered by experts

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.

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

Signs that your A/C system needs professional service include increased energy bills, uneven or poor cooling, loud or unusual noises, and frequent cycling.

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

You can air condition your Arizona room by extending your home’s existing HVAC system or adding a ductless mini-split system. Arizona rooms that have full windows rather than screens only are a better choice for air conditioning—screens will let the cold air out as fast as the air conditioner can make it.
