How much does it cost to fix a broken AC?

This depends on the type of repair you need to get your unit functioning properly. On average most AC repair’s run about $200, max is around $300. If you own a new home, most parts can be replaced with a warranty and you only pay for the labor. Depending on the company you choose, you might end up paying a trip fee on top of the repair, while others will waive the trip fee if you hire them to do the repair.

When should you repair or replace your HVAC unit?

Most HVAC systems will last 10 to 15 years, depending on the brand, use and geography/climate. If you run your AC unit 24/7 in Texas you can expect more wear and tear. If you properly maintain your unit, you can avoid the headaches of mid-summer repairs. Proper maintenance usually entails cleaning the filters, ducts and checking the mechanism for preemptive repairs. 

Should I replace my AC compressor or replace the entire system?

The compressor is the most misdiagnosed repair when it comes to HVAC technicians. First, you should ensure you have a trustworthy company.  Next, check to see if your compressor is still under warranty. This will save you quite a bit of cash and you will only pay for labor. If you are not under warranty, you should consider replacing the entire unit. Replacing the unit is a bit more expensive than replacing the compressor, but sinking the cost of a compressor into an aging HVAC unit may wind up costing you more in the long run.

Why is my outside AC unit making a loud noise?

If your air conditioner is making a loud noise that sounds like metal on metal, you should first check the bearings on the fan. If this is the case you will need to replace the fan motor entirely. 

Whats wrong if my HVAC unit is making a clanging or banging noise?

The most likely scenario is that your fan is hitting something. It could be something that fell into the unit. We regularly find sticks from trees fall i. The other reason could be that the fan has gotten lose from the mount and hitting the cage.

Service First AC -

AMAZING SERVICE!! I am so happy that I found Service First! Not only did they show up after hours (9pm) w/in 20min of me calling them, they diagnosed & fixed the problem w/in 5min of looking at the unit. It’s cold & I saved a TON of money choosing Service First instead of going with someone who told me another part was broken. Jack gave great service, fast service, and WE ARE ONE HAPPY FAMILY with this Texas HEAT!! I completely recommend Service First and they did a hell of a job. It was HOT in my house. Now we can all relax in the COLD COLD AC! Thank you so much!!

I have an older home and while my inside unit is a bit newer the outside unit is quite old. I returned home to a very HOT & HUMID house last weekend in the early evening. It was miserable! I called Service First and a technician was at my house in no time. He was very courteous, mindful of the time of night and quickly determined what the issue was and set to work fixing the unit. He was able to replace the compressor and get the unit back up and running. This is not the first time I’ve used Service First and it won’t be the last.

Service First AC -

Service first is hands down the best air conditioning and heating company in San Antonio. I called two other places and they could neither accomodate me or give me a fair price. Service first came the very next day and got the job done in half the time and were very affordable. They even sent additional trucks to get the job finished in time with no extra charge. Not only did they keep their word but were very knowledgable and professional. They were very friendly and answered all my questions. Thanks Juan and Esteban for all your hard work, you guys rock.

When my a/c stopped working in this heat I was sunk. I contacted Jack at Service First Mechanical and he came to my aid. After an initial diagnosis the problem was grave, but he came up with an innovative solution to help get me on my way. At a minimal cost and a job well done, an hour later my a/c was working better than it was before. I rate this company as a 5 star and will recommend them to others.

David Villegas did a great and thorough job on our AC. We will definitely use service first again. Great employees great prices. You can’t beat that. Thank you again David!

Service First AC -

Service First was exceptional, and I would definitely recommend to anyone in the San Antonio area. Very prompt service and David was extremely helpful and polite. He explained any problems and questions we may have had.

Service First AC -

I was desperate and Jack from Service First came to my rescue! I had been waiting 5 days for my property management company to fix my AC, they either didn’t show up at all or fiddled with it and said it was fixed when it wasn’t. It was late on a Saturday afternoon, he came quickly at the time he said he would be here and had it up and running in less then a half hour. Thank you, thank you, thank you!

Service First AC -

You call, they answer, they are on time, they repair or replace. Fair pricing, technicians take the time to explain, pleasant and personable, honest. Owner oversees and takes responsibility and ownership of his business. Techs are neat and clean behind themselves. Work until the job is complete and done right! Quality that needs to be shared with other industries……very happy and have saved money by choosing the right system.

Service First AC -

Brandon Jonas, the technician for Service First came to my home and serviced both a/c and heating systems. He arrived on time, which was a surprise based on my experience with other companies. Brandon was courteous and professional in his actions and appearance. He took extra care to protect our flooring. He did an excellent job and offered so suggestions for making our unit last longer. I would recommend Service First to anyone. I will be using their service in the future.
