Heating, Air Conditioning, Fridge, HVAC/crankcase heater


We live in San Antonio, Texas and have a 14 year old Trane TWX036C100A2 unit.  It has been good to us over the years.  The crankcase heater shorted out this week.  The service tech recommended we not spend the $235 to replace it due to the age of the unit and the not-so-cold winter temperatures here.  I understand what the heater does and how it works.

Can you offer an opinion on his recommendation?  Do you think we might be nearing the end of this unit's lifespan?  Life is tough for an ac unit in Texas!


Like you, I live in The Lone Star State (life long Texan!)...and, yes...the severe summers here
wreak havoc on an HVAC system. If your system is, indeed, 14 years old, I also would recommend
replacing the entire system. Your furnace is the air-handler for your a/c unit in the summer (it all works together).
In my opinion, you are better served upgrading the entire system, and going to either a 14 SEER complete
system or, my favorite, a 16 SEER 2 stage system for maximum comfort & efficiency.

I recommend either a Lennox 16 SEER 2 stage, or an Amana 16 SEER 2 stage. Be sure and take advantage of  the
10 year parts & labor warranty that is offered, and on the Amana the warranty includes LIFETIME compressor/condenser

Good Luck!

I can answer most fundamental questions about Air Conditioning and how it works. I can give advice on different services in the DFW area, as well as lend some advice as to pricing systems along with solid opinions as to quality equipment versus sub-standard equipment. I can help educate consumers with regards as to what to look for in a service company, as well as steps they can & should take when considering repairing vs replacing their A/C equipment.


I was the Sr. Sales Technician for one of the most well-established HVAC (residential) companies in DFW for over 5 years. I then became the Dallas Team Leader for another well-established DFW company based out of Ft. Worth. Became the Sales Manager for an area A/C business most recently.

I have written content for several area HVAC (residential) businesses with respect to their Sales Policy manuals. I personally wrote the Sales Training Manual for a well-established DFW area HVAC company.
