Have your air conditioning/heat system inspected

at least once a year to make sure it’s operating efficiently, and to diagnose and make simple repairs before they become costly, major repairs.  Regular maintenance of your air conditioner/furnace is a small investment that will give you a great return by keeping your system operating properly, and cooling or heating your home effectively, for many years.

Having your semi-annual Heat/AC System Check-Up is similar to having your vehicle serviced on a regular basis.   Just like a car, your air conditioning/heating system will last longer and run better if it’s well taken care of.

An Air Conditioning-Heat System check up includes lubricating parts as needed.

Do you take your car in for an oil and lube on a regular basis?  Of course you do!  Your older air conditioner may need lubricating as well.  Our air conditioning check up includes inspecting bearings and lubricating moving parts as needed.  That alone is worth the cost of the check up – keeping all those parts moving as they should!  Newer units are sealed, and don’t need lubricating, but they still need regular check ups and periodic maintenance.

Our AC-Heat System Check-Up Inspection

will be tailored to the particular needs of YOUR home’s hvac system – whether it’s gas or electric, five years old or 20 years old, etc.

Don’t be fooled by those 20-, 30- or even 40-point inspection gimmicks.  Our Air Conditioning inspection will include all points necessary to make sure it’s a thorough inspection of YOUR air conditioner.

Every HVAC Tune Up and inspection includes these very important points:

.  Inspecting and tightening electrical connections.  Loose wiring is a common maintenance item, especially in homes that have aluminum wiring.  Wire expands and contracts with the flow of electrical current.  This expansion and contraction can loosen the connections, causing the wires to heat up, and the connection to fail.  Checking the electrical connections to your air conditioner is a relatively minor maintenance function, but it’s important to have this done on a regular basis.  Loose connections can mean your unit stops working.  You can read our blog about a personal experience with that here;

.  Checking refrigerant pressure.  While in most air conditioners the amount of refrigerant that “leaks” from the system is quite small, it can still result in the pressure dropping enough to impact the functioning of the unit.  Like the lubricant or antifreeze in your car’s engine, the refrigerant in your air conditioner lubricates and helps cool the compressor, which keeps it cooling properly and extends the life of your air conditioner.  It’s important to make sure your ac system maintains the recommended refrigerant level;

Checking contactors.  When the thermostat says “go”, the contactors send a signal that starts your hvac system.  A bit like turning the key in your car’s engine, these two pieces of metal coming together allow a voltage arc that sends the signal.  Just through normal wear and tear (this voltage arcing can cause the metal to burn out or can cause things like pitting of the metal which interferes with normal functioning) these contactors fail.  And, of course, if the contactors fail the unit won’t start.  Periodic replacement of contactors is part of the normal maintenance of your air conditioning unit;

.  Checking the run capacitor.  A weak or non-functioning run capacitor means your motor has to work harder to start, which can cause it to overheat and can result in damage to the motor resulting in a costly repair.  It will also put additional stress on your air conditioner’s compressor.  More compressors fail due to faulty capacitors than for any other reason, and if your compressor goes, you’ll be investing in a new air conditioner!  Yet, a simple capacitor test can let you know of potential problems before major damage has been sustained;

Checking amp draws on the motors.  Testing the motor to make sure it’s not drawing high amps (meaning it’s running hot) is necessary even when the capacitor tests fine.  Sometimes we find that a weak capacitor has been replaced but unfortunately, it was replaced after the motor had sustained damage, putting the compressor at risk.  It might mean your motor has to be replaced, but this is definitely less expensive than replacing a compressor, something we rarely recommend anyway since it’s very costly and comes with very little warranty.

In addition, our thorough HVAC Tune Up and Inspection will also include:

  • Replace filter (customer supplied)
  • Check thermostat
  • Check temperature split (exiting air temp and returning air temp)
  • Inspect service disconnect
  • Check fuses
  • Inspect contactors, relays and capacitors
  • Inspect electrical safety circuits
  • Check indoor motor voltage and amperage
  • Check outdoor motor voltage and amperage
  • Check amp draw of compressor
  • Inspect bearings and lubricate moving parts, as needed
  • Inspect outdoor coil run and test system
  • Inspect Air Handler/Elbow for Air Leaks
  • Inspect Compressor (main line) contactor
  • Load test (check) all applicable run capacitors
  • Inspect evaporator coil
  • Check drain pans
  • Check operation of water overflow prevention switch
  • And anything else necessary for a thorough inspection of your specific air conditioning system!

Proper maintenance of your air conditioner/furnace – including regular hvac inspections – is a relatively small but very worthwhile investment that will keep your system working properly for many years.  But when you need a new air conditioner or furnace installed, remember – we can help with that, too!

Reminder: change the filters in your air conditioner at least once a month.  More often, if you have pets that shed a lot, if you have someone living in your home who’s highly sensitive to allergens, or if some other situation, such as having remodeling done in your home, is creating dirty, dusty conditions.

And, use disposable filters!   The filter in your air conditioner traps dirt, dust, pet hair, spores, pollen, etc. in order to remove these from your home as well as from your ac system.  Washing a reusable filter will NOT thoroughly clean these contaminants from the filter.  Over time, that reusable filter will get a nasty build-up that will make the filter ineffective.  We never recommend reusable filters.  Disposable filters are the sanitary solution!

One more point that’s important, but isn’t common knowledge.  If your ac is a split system and the air handler is in your attic, you should have your condensate lines, in particular the primary drain line, blown out at least once a year.

The primary line drains near the base of your home, on an exterior wall often located where debris (from things like mowing lawns, blowing leaves and dirt from a walkway or patio, and other landscape maintenance activities, as well as spiders webs or even slime build up from the condensate drainage itself) can lead to the condensate line being blocked.

If this happens, the condensation building up from your air conditioner will overflow into the attic, damaging insulation, soaking beams and trusses, and eventually leading to ceiling damage – oftentimes major damage.  A visual inspection of the drain lines is not enough to make sure that the lines aren’t blocked. We always recommend having the lines blown out to clear them at least yearly to protect against the possibility of water damage.
