HVAC Contractors Altadena, CA: Heating & Air Conditioning Installation, Repair & Tune-up Services

Summers in Southern California can be famously long and hot. During a heat wave, one of the last things you need is a broken air conditioner, leaving you and your family sweltering while you wait for an AC repair.

And when cold winter air comes in from the ocean or down from the mountains, suddenly finding out that your heater isn’t working isn’t going to leave anyone too happy. Anyone who’s ever spent a night shivering under a pile of blankets knows it’s not a chance they want to take again.

So you want your heating and air conditioning system, often called your HVAC system, to work properly. It’s critical to the comfort and sometimes even your family’s safety.

Finding a good HVAC contractor can be challenging, though. For starters, there’s no shortage of them, especially in a heavily populated region like the greater Los Angeles area. There are also a lot of what we call “Cheapie Charlies” out there, contractors that offer enticingly low rates when the reality is that they’re uninsured, insufficiently skilled, or likely to hit you with high additional costs at the end after providing that low quote to start with.

Cheapie Charlies can cost you a lot of money and frustration by the time it’s all over, and you can avoid the risk of dealing with one by going with American AC Heat Plumbing for HVAC services. American is an established, widely recognized regional leader who has been serving L.A.-area homeowners for years and has built a reputation for honesty, reliability, and quality.

Our HVAC services include tune-ups for maintenance, repairs to get things back to normal as soon as possible, and installations when it’s time for a new system. We’d like to explain them in a little more detail.


Mechanized units need routine maintenance in order to keep your system running smoothly. One of the best examples is a car. You know that you must change the oil regularly, bring it in at recommended service intervals, etc. This is also a way to catch minor problems before they become big or dangerous ones and to remain in compliance with warranty requirements. If your car experiences major mechanical failure and you haven’t been bringing it in for its required tune-ups, you may be stuck with the total cost of the repairs.

HVAC systems work this way, too. Servicing them at least once a year helps ensure they’re running properly and efficiently, keeping you and your family more comfortable and saving you money on energy bills. It’s also an opportunity to make minor repairs and adjustments before you end up with extensive, expensive repairs at the worst possible time. As with a car warranty, having the recommending servicing performed helps you comply with warranty requirements.

American offers a $129 Precision Tune-Up Special to help with all this. This 22-point service entails a professional cleaning and a close inspection of your system and all of its components. We’ll also perform any needed adjustments and repairs at the same time.

We guarantee results with our Precision Tune-Up and back them up in writing. You’ll get a full refund if you don’t see your power bills go down by at least $129 over the next five months following service. Yes, our tune-up pays for itself either way! All parts and labor are guaranteed as well over those five months.


You can follow your car’s recommended service plan to a ‘T’, but you’ll still have to make repairs from time to time. Sometimes a part just gets too old and stops working. Other times, parts break. Parts like tires and brakes get worn over time to the point that they aren’t safe anymore and need replacement.

When your HVAC system breaks down and needs repair, time is of the essence. No one wants to be stuck in a hot house on a hot day any longer than they need to be.

At American, we understand that, and we make a point to get out to you and get things back to normal as soon as we possibly can. As with a tune-up, we guarantee the work. In fact, we don’t leave until things are back to normal.

We also know that HVAC systems sometimes seem to have minds of their own and pick the least convenient times to break down. That’s why we have 24/7 emergency service available for those times when it absolutely can’t wait.


Sometimes, the best thing to do is to get a brand-new HVAC system. You might come to that conclusion for a number of reasons:

  • The unit’s old, and you’re worried about how much longer it has and don’t want to find out the hard way.
  • Repairs are becoming more frequent, costs are piling up, and a new unit is making more sense.
  • You want a newer, more efficient system that will save you money on energy bills.

When you decide it’s time for a new HVAC system, American can expertly install a modern, efficient system that will take good care of you and your family for years.
