AC Drain Line 101

Fix It Yourself AC

The most common service call i get throughout the year is a CLOGGED DRAIN LINE ! It does not matter if your air conditioner is old or new this can happen to you. If overlooked this can cause irreversible damage to your AC system and possibly to your beautiful home.  Last year i had 309 services calls related to the drain line an average of almost 1 per day. This Problem is by far the easiest to fix as well as prevent.

Why Does The Drain Line Clog?

  • Dirty Filters
  • Algae Build Up
  • Lack Of Maintenance
  • Outdoor PVC Blockage

What You Will Need 

For cleaning (1 of the 2 will suffice)


Then for prevention (1 of the 2 will suffice)


Don’t use bleach. Bleach will damage copper, plastic and PVC. It will also caused the joint to leak by eating the glue away. People say use it when the AC is on in the summer because the water is washing it right out. However that’s not the case when it’s clogged or when there is little humidity the bleach can sit in there.Why use something that will eat the pipes and glue. Use Drain line cleaner or vinegar. Both work  just as good and does not damage the pipes.

Want To Add 5 Years To The Life Of Your Compressor?

Does your compressor make a hellacious noise upon start-up?

Do your lights dim every time your unit turns on ?

Adding a Hard Start Assist to your system can erase those problems and add at least 3-5 years to the lifespan of your compressor. That’s not even the best part, the best part is you can install it yourself for under $50.

What is a Hard Start Assist?

A Hard Start Assist stores energy inside it’s capacitor and when the unit turns on it uses that energy to aid the compressor upon start-up. After start-up the Hard Start Assist then uses the power from the unit to recharge itself so it’s ready to help again on the next heating or cooling cycle.

How Much Should I Pay For A New AC Unit?

ac repair tips

Purchasing a new heating and cooling system for you home can drive you crazy. What Brand? What SEER rating? Heat pump or Straight cool? First things first don’t loose sleep over deciding on your new machine. Buy from someone you like and who works for a company with a good reputation.

What you should look for when selecting your company.

  • Google Reviews, Customer Testimonials, BBB rating. In that order just because a company is A+ on BBB doesn’t mean they’re the right company
  • A technician that knows their stuff and loves the company he or she works for
  • Warranties and Guaranties offered that go above and beyond the manufacturers warranty
  • 24 hour service
  • Offers financing and/or rebates

What To Know When Deciding On SEER rating 

SEER rating stands for seasonal energy efficiency rating. So basically the higher the SEER rating the lower your electric bill will be. Right now the minimum SEER rating is 14. In order to Qualify for most government rebates you will need to install 15 SEER. Anything you purchase that is 16 SEER and up i highly recommend changing your ducts as well. The reason i say that is because often times 16 SEER equipment requires much larger ducts to achieve the efficiency.

What Brand

Brand of equipment isn’t nearly as important as you might think. 90% of your unit’s lifespan is going to depend on Installation and maintenance. If you are really interested in which brands i think are the best please refer to my previous post AC Unit Power Rankings.

How Much

There is no right answer to this question. My company charges between 6 and 10k for an installation price all depends on size, SEER rating, and the company. Whatever you do don’t let friends or family dictate your purchase. When purchasing a heating and cooling system you want it to be your decision don’t let anyone force your hand you will know if you got a good deal or not once the whole experience is over with.

The Purchase 

After you have gathered your estimates, hopefully no more than 2 or 3  PULL THE TRIGGER! Just do it your life is way too important to waste time getting 10 estimates or researching model and serial numbers.


When calling the company you choose tell  the Technician or Manager you are willing to proceed with the work if they can do it for $500 cheaper.




Has Your AC guy ever told you that you need to add Freon to your machine? Did you really need it? Today I will be sharing some info on what you need to know about Freon.


R-22: The old stuff. If your heating and cooling system was installed before 2009 there is a good chance this is the refrigerant your machine runs on. This
refrigerant is currently being phased out by the EPA due to the fact that when it leaks the gas depletes the ozone. R-22 is  expected to be gone by 2019.

R-410a: The new stuff also known as PURON. All new AC systems since 2010 are manufactured to run on PURON. R-410a does not contain bromine or chlorine which causes ozone depletion This refrigerant also allows for a higher SEER rating on your air conditioning and heating system.


The answer to this question is simple…..NEVER. Your heating and cooling system is a sealed circuit. The condensing unit outside pumps the Freon as a liquid to Your air handler where the evaporator coils change it from liquid to gas. The gas then proceeds back to the condensing unit where the condensing coils change the FREON back to liquid. If your AC guy tells you that you need to add FREON ask him why. There are two reasons you will be low either someone let it out or most likely you have a LEAK. Don’t let your AC company charge you for FREON every year without finding out if or why you actually need it!

Target PSI

*Pressures may vary up to 5 psi higher or lower due to outside temperature

R-22:           200 over 75

R-410a:     300 over 125
