A broken HVAC system means more than an uncomfortable home; your system impacts everything from the moisture level and air quality in your home to your overall energy consumption and costs. The HVAC repair company you choose to work for your home or business has an enormous impact on your comfort and costs -- choose wisely, and you'll end up with a cool, comfortable home and the lowest possible energy bills.

Expert Air Conditioner Repair

If your system is suddenly making noises, you smell a musty odor or your air conditioner seems to be constantly running without effectively cooling your home, t is time to have a professional air and heating repair specialist take a look. A service technician can examine your system and let you know what is wrong; he or she can also provide you with an estimate of what it will cost to repair your system and the anticipated amount of time it will take. It is essential to choose a company with skilled technicians -- not salespeople -- to evaluate your system for you. When you need a repair, the last thing you need is a sales pitch; you need an honest and comprehensive idea of what the repair will cost and how it will benefit your home.

HEATING & AIR repair & service


How do I know what size system do I need?


If you are replacing an existing system in your home, most likely you should install the same size as what you currently have.  Despite all the calculations and programs we have at our disposal, we find the most accurate way to determine if this is the best course is your input.  Heating is rarely a problem in our area, so we would ask you, when it was over 100 outside, how did your system perform.  If it was good, then there is no need to change anything.  Only if you have problems keeping your home comfortable on hot days should you consider upsizing.  You should also consider looking at other ways to reduce your heat load as well such as adding some insulation to the attic or making sure your ducts are adequately insulated and sealed so they are not losing a great deal of cooling while the air is traveling thru your 160 degree attic.  

Upsizing involves much more than just buying a larger system.  The infrastructure MUST be able to support the increase in capacity or not only will you not get maximum performance and efficiency, it can lead to serious problem, drastically shorter lifespan and increased parts failures.  The Freon lines must be the correct size for the larger air conditioner.  The electrical wiring must be sized properly for a higher electrical load, and the duct system must be sized large enough to allow for higher air flow.   It is also possibly that you may benefit from a smaller size as well.

If you are installing a system in a new home or a home that has not had central heating and air before, the sizing should be based on a review of the structure taking into account how it is built, and then calculating the size based on the tools we have available.  Sizing off of square footage alone is risky.  You can have two structures next door to each other of identical square footage.  If one had lots of older windows and many are facing south with no shade, and has less insulation in the walls and attic, and the other has less windows that are newer and more efficient, more insulation in the walls and attic, these two buildings would need drastically different size systems to heat and cool them properly.

Talking with a knowledgeable contractor about your home is the best way to determine what is the best size for you.


What is the best brand of heating and air conditioning equipment?


Our answer to this question is probably unlike the answers you will get from most companies.  And that is that there really is no “best” brand.  The founder and most of the employees here have worked for decades in this business and have serviced, sold, and installed every brand and type of equipment made.  The founder alone has 30 years’ experience with all brands.  

Many people do not realize there are only a few manufactures making many brands of equipment.  Multiple brands of equipment literally come off the same assembly lines, just with a different paint job and label.  Others may be made in different locations, but are made of the identical parts and components, again with just a different paint color and label.  And even different manufacturers get the major components such as electric motors, compressors, gas valves, etc from the same couple of sources.  Our answer to this question is the best brand of heating and air conditioning equipment is the company that installs it, and getting the best bang for your buck.  

This is not to say that every manufacturer hasn’t put out a real stinker at some point, they all have.  We have had to deal with specific models that had problems.  A good example is a new modulating ultra-high efficiency furnace that came out about 2006.  This particular model ended up experiencing a lot of issues with a certain part failing a lot.  We stopped selling this model until the bugs were worked out and it is now as reliable as anything on the market.  We stood behind our warranty for those who unfortunately had to call for service and took care of our customers.  We constantly monitor the market for signs of a certain unit that is experiencing higher than normal service rate.

Installation is critical as well. If your duct system is not big enough to allow the right amount of airflow, or your refrigerant lines are not sized right, or any number of factors are not correct, the life of your system or frequency of breakdowns can be impacted. Most people that experience service issues with their system think they bought a bad product when in fact it was the infrastructure connected to it.  And just because your last unit ran 20 years with no problem doesn’t mean you may not have any external issues.  Old equipment is like old cars.  Very simple under the hood.  And just like with cars, new equipment is full of complex components, electronics, sensors and safety’s.  New equipment is affected more by incorrect infrastructure much more than an old unit that just kept on running no matter how restrictive the duct system was or if the flow of refrigerant was not quite right.  Don’t be sold by glitzy marketing or pushy sales people trying to convince you that whatever it is that they sell is the best there is and everything else is junk.  Get it installed right by a great company and likely whatever brand you purchased will be the best brand!


Do tune ups really give me any benefit?


YES!  A tune up is maintenance on your machine.  It is primarily like a physical you get at your doctor.  Checking all the vital signs looking for indicators of possible problems and addressing them before they become more serious.  We experience many calls for service that turn out to be a wire or connector that came loose, carbon build up on an electrical contractor, or a sensor that simply became dirty.  I recommend not putting a lot of stock in claims that a tune up will cut your electric bill. Regular maintenance is intended to KEEP your equipment in good shape.

If your system is in good shape, a tune up will not reduce the amount of energy it uses.  If a dirty blower or coil is found and then cleaned, that will result is reduced power consumption and better performance, but the primary reason and benefit for having regular maintenance is keeping your equipment performing at its best, and heading off breakdowns over minor issues or at the most inopportune times.  You should also know that while rare, it is possible every component of your equipment checks out great and a short time later a part or motor fails. It can and it does happen.  If this occurs, we do offer our no breakdown guarantee.  If you need a repair in the same season after we do a maintenance, we will refund the cost of that maintenance in full, no questions asked.


Should I have my Freon “topped” off?


NO!  A refrigerant system is a sealed, closed loop system.  Unless it develops a leak, it should never need Freon added.  Beware of companies that tell you that you need to do this.  If you are actually low on refrigerant, then your system has developed a leak somewhere.  Refrigerant leaks can range from simple to find and repair to very difficult to find and expensive to repair.  While most all companies will recharge a low system, it is technically against the law for an EPA certified technician to add refrigerant to a system knowing that it will leak out.


How often should I change my air filter?


There is no certain frequency to answer this question.  It is based on your filter type and your home environment.  Typical is about once a month.  You should check it at least that often.  If you find that it is not very dirty, it may need to be changed less frequently.  There are some types of filters that only need changed twice a year.  

The most important thing is to check them regularly.  As a filter becomes dirty, the filter starts to clog up reducing the amount of air getting thru.  While you may not even notice any difference in your home, as the airflow decreases, your furnace can run hotter, the blower motor will start working a little harder, and Freon will absorb less heat from the air reducing cooling and also making your compressor work harder.  This leads to reduced life of the system.  Eventually a filter can become clogged enough that your system will actually stop working.  This is a more common cause for service calls than you might imagine.
