AC Repair Service In Tucson, AZ

AC Repair in Tucson, AZ and Surrounding Areas

At some point in the life cycle of your AC system it will need repair. Hopefully, your service tech can catch these issues before they arise and properly tend to them during an AC service or maintenance. There are some things that you can try yourself that might be a simple fix, or it might indicate that you need an AC repair.


Many times, your HVAC system will give you clues that you need repairs. However, that is not always the case. Here are some warning signs that you may need an AC repair soon.

Unit Won’t Start and Run

If your AC system doesn’t start when turned on you can try checking the thermostat to make sure it is set where the unit will respond to begin operation. Sometimes all the AC system need is for the thermostat to be lowered to allow the signal to be sent from the thermostat to the compressor to begin its operation cycle. If the unit does not respond to any input from the thermostat, then you might need to schedule an AC repair.

Circuit Breaker Tripped

Another circumstance that would cause the unit not to run would be the tripping of the circuit breaker. Make sure this hasn’t happened, and if the breaker has tripped properly reset the breaker and observe the unit for a few moments to be sure it doesn’t trip again. If the unit is constantly tripping the circuit breaker, then you need to schedule an AC repair.

Unusual Odors or Noises

If your HVAC unit starts to make unusual noises, it could be a sign of a part breaking down. Odd smells can be a sign of leaks or burnt oils that are precursors to breakdowns. You might have a blocked drain line on the condenser coil. This can be detected by the end of the drain line being dry, and the possible sound of a fan hitting water. The drain may be clogged, and the condensation is not flowing away from the unit but is backing up into it and about to cause further damage. In this case, turn the unit off, and schedule an AC repair.

Rising Electric Bills

A rise in your electric bill can signify that your system is running harder and hotter due to a failure somewhere in the system.

The Vents Are Blowing Hot Air

This could be a sign of blocked air flow or a failing compressor. You need a professional that can inspect every component of the system including your ductwork. Not addressing this quickly can lead to bigger problems.

Rapid Cycling

When the weather gets scorching hot in Arizona, you can expect your AC unit to come on more often. However, the intervals between when the unit is operating should be uniform. If you notice your AC turning on and off more frequently than usual, even on days that are not so hot, then you may need AC repair service or a new unit.

Unit Turns on But No Air Blows Out

This can be a sign of a variety of issues, such as a faulty blower or blower motor.

Ice forming in the System

Your air conditioner is supposed to be cold. However, if there’s ice forming then there’s a problem that needs to be addressed quickly! You will probably be able to recognize this problem due to the pool of water forming under your air conditioner. This is not a problem that will correct itself.

Just be always aware about the running condition of your AC system. Taking this proactive approach should keep your AC running at peak performance for years to come!


There are some common air conditioning unit repairs, such as:

Air Filter Replacement

This filter is your AC’s first defense against trash and debris entering the system. When it gets clogged, it causes all sorts of problems.

Failed Thermostat

Your thermostat measures the temperature in your home and determines when to turn your air conditioner on and off. When it isn’t calibrated correctly, it can keep your home from cooling.

Dirty Air Condenser Coils

Warm air from your home travels over these coils becoming supercooled. If they fail, you need to replace them to cool your space again.

Leaks and Freon Replacement

Freon is a gas that helps to super cool the air in your AC before pushing it back into your home. If you have a leak, your freon escapes into the atmosphere. You need stop the leak and then recharge the freon to cool your home again.

Electrical Issues

Electricity by nature can cause heat if connections are not tight. Add to the fact your unit is working hard during the summer just adds more heat. Electrical components such as control boards, motors, run capacitors, contactors, etc. can become so hot that they begin to burn out.

Is it OK to repair vs. replace my AC system?

If your system is under 15 years old, uses R-410a refrigerant, and is overall in good condition (no previous leaks, no rust, is clean, and you have regular six-month maintenance done to it, then repairing makes sense.

However, if your system is over 15 years old then you should seriously consider replacing it. Most of the systems of that age still use R-22 freon which has been discontinued. Because of supply and demand, the remaining R-22 that is available is drastically going up in price. As of now, it is going for $300 per pound. A normal house can have a system that requires 10-19 pounds of refrigerant. So, if you have a leak that caused all the freon to escape, the cost just for R-22 alone I could run you $3,000 – 5.700 plus the replacing the part and labor to fix. Why spend $5,000 to fix an old unit when a new energy efficient one can be purchased for a few thousand more? Here it makes better financial sense to replace the unit.
