Vacuum Done Right

By | February 21st, 2013|Categories: Uncategorized|Comments Off on Vacuum Done Right

As spring approaches quickly and summer isn’t too far off, tens of thousands of Dallas residents are contemplating A/C replacement.  The prospect of getting rid of that old, inefficient HVAC system and replacing it with a technologically advanced, high-efficiency new system is an idea that gets homeowners both excited and anxious.  And in fact this time of year is a great time to be proactive in replacing furnaces, coils, condensers and heat pump.  Truly “tis the season” to invest in your home’s comfort and to also start saving serious money.  In this month’s blog we wanted to dedicate a few minutes to what we at Classic Heating and Air think is the MOST important part of the air conditioning installation (sometimes repair) process, pulling proper vacuum.

Pulling vacuum is the process of evacuating a refrigeration or air conditioning system (including refrigerant lines, coils, etc) of all unwanted contaminants and particulate primarily dirt, water and air.  This is done by lowering pressure within the system to reduce the boiling point of water, at which point (generally 27.75 inches Hg) vaporization occurs.  The process of pulling vacuum is performed to rid the system of these potentially harmful substances to ensure that the refrigerant in the system has a clean, pure environment in which it can operate best.  Not pulling proper vacuum can lead to:

  1. Premature corrosion
  2. Line restrictions
  3. Mechanical breakdown (compressor, expansion valves)
  4. Lower efficiency
  5. Ultimate system failure

From industry manufacturers and popular HVAC resources there are several guidelines and requirements of pulling a good, proper vacuum.  This list includes:

  1. Using a high-accuracy digital micron gauge
  2. Removing valve cores
  3. Larger, high-rated hoses and manifolds
  4. Changing the vacuum pump oil after every installation
  5. Pulling system down to at least 300 microns
  6. Allowing system to stand for 20-30 minutes following pull-down


At Classic Heating and Air we are proud to follow these steps and others during EVERY air conditioner installation.  We believe that a job done right the first time is both expected and appreciated by our customers and actually is more profitable to our company by avoiding callbacks, repairs, and warranties. The common problem throughout our industry however is that many companies and/or technicians are either not properly trained or do not dedicate the proper amount of time to correctly pull vacuum and properly repair or install air conditioners.

So as one can see an installation is not just an installation. Pulling proper vacuum is essential for your air conditioning investment to operate properly, efficiently and ensure a long trouble-free service life. This spring and summer whomever you choose to install your air conditioning system make sure they are doing it right…ask questions, get involved. If that company cannot answer your questions or show you exactly what,when, or how they are installing your new air conditioner then give Classic a call!  When we say our service “goes Two”, that means our installation process does as well!

Carbon Monoxide Part Deux

By | December 9th, 2012|Categories: Uncategorized|Comments Off on Carbon Monoxide Part Deux

We had so many inquiries and response to our October blog about carbon monoxide we decided to write a follow-up to help customers further understand the infamous gas, where it comes from and how it can become a  potential in-home threat.

Most metroplex homes utilize gas furnaces as their source for heat and put in simple terms a furnace is a controlled fire that when installed and operating properly is a very safe, efficient way to heat your Dallas, Plano or McKinney home.  In fact an author of HVAC operation manuals recently put it quite bluntly stating, “they do not make these things to catch fire, blow up or kill people.”  However, if problems do develop you and your home’s heating system system could be the victims of a carbon monoxide leak.  Here are the 5 most common problems we encounter here at Classic Heating and Air that can lead to CO leaks and what you can do to prevent them.

1.  Compromised heat exchanger – A heat exchanger (HEX) is arguably the most important (and expensive) part of your furnace.  A cracked or rusty HEX not only reduces heat transfer but allows CO to leak outside the furnace cabinet.

2.  Insufficient combustion airInternational Fuel Gas Code has very strict requirements when it comes to gas furnaces in enclosed spaces.  Many numbers, calculations and     considerations must be accounted for to ensure the proper air flow for the proper fuel burn off.  If not done perfectly your furnace will not doubt produce sulfuric acid, black soot and carbon monoxide.

3.  Broken or disconnected flue pipe – Serving as your furnaces exhaust pipe, the flue pipe is responsible for getting all the gas and fumes up and out of your home.  If that pipe is restricted or broken somewhere along the line, the exhaust has nowhere to go but out into your home.

4.  Incorrect gas pressure – Too much or too little and your furnace operates outside it’s intended range.  Just like a car running too rich or too lean, not all the fuel is burnt off which leads to waste and excess fumes and byproducts.  Not to mention an inefficient furnace and your paying higher energy bills!

5.  Worn out draft inducer motor – This mechanical component is installed in the direct stream of flue gas, if seals and bearings aren’t in great condition CO gas is allowed to slip through and escape.

These are just a few of elements and details that go into safe, proper, efficient gas furnace operation.  Our best recommendation is to have a reliable, trusted HVAC contractor out at least once a year to inspect the above mentioned items as well as many other things on your home’s system.  Doing so will not only save you money, but ensure your family’s safety.  Here at Classic we have several ways to tackle that task, either with our one-time famous CLEAN/CHECK/TUNE or by signing up for our yearly heating and air conditioning maintenance you can sleep well at night knowing your system is in tip-top shape.

Give us a call today and

Happy Holidays

Don’t Be Spooked By Carbon Monoxide

By | October 17th, 2012|Categories: Uncategorized|Comments Off on Don’t Be Spooked By Carbon Monoxide

Remember the winter of 2010?  The Superbowl?  The ice? Rolling blackouts?  Well, El Niño is moving into North Texas again this year and some of those same staples of the famed weather pattern we saw in 2010 are predicted to invade us here in Dallas in 2012.  Accompanying the brief periods of frigid cold and winter precipitation is the increased use of your home’s heating system; whether that be a Dallas furnace, a Frisco heat pump, or an Allen air handler.  In this month’s Classic Blog we want to take a quick minute to look at the use of gas furnaces and the subsequent issue of Carbon Monoxide.

In 2011 alone there were 208 recorded CO cases in Dallas and nearly all of those had working Carbon Monoxide Detectors!  The key to safe, efficient operation is ensuring proper exhaust ventilation, sufficient combustion air, and exact gas pressure to name a few.  If you haven’t had your system inspected or tested recently call Classic Heating and Air today for our famous CLEAN/CHECK/TUNE.  The most common problem with Carbon Monoxide arises when technicians are ill informed and/or poorly equipped to detect problems.  Or even worse, use the threat of Carbon Monoxide as a scare tactic toward you and your family.  This fall and winter, as it becomes time to turn on your gas furnace protect yourself and your family by following these great Classic Heating and Air tips:


  1. If you have CO detectors in your home, test them annually and change the batteries often (included with our famous Classic CLEAN/CHECK/TUNE).
  2. FACTS are FACTS.  If something a company or technician tells you seems unclear or hard to follow…ask them to show you what that means.
  3. Not all tools are created equal.  Just because they beep or make noise does not   mean they are fit or authorized for CO detection…ask to see the label.
  4. Heat exchangers rarely crack these days.  If your current furnace is 15 years or   newer odds are the HEX isn’t cracked.  The technology and material used today in furnace manufacturing makes heat exchanger problems a thing of the past.
  5. Manufacturers DO NOT make furnaces that catch fire, blow up, or kill people!     There are exceptions and limitations to this statement every qualified technician should know…if they don’t, call Classic Heating and Air immediately!
