If you've been delaying maintenance of your furnace or air conditioner, your HVAC system is not operating at optimum efficiency. Further, most furnaces and air conditioners breakdowns are directly related to little or no maintenance - often resulting in premature breakdown of your system components.
Littleton Heating, Air Conditioning and Electrical, NATE certified technicians will inspect, clean and tune your furnace and air conditioner, which will insure a safe and comfortable winter or summer season for you and your family. We offer planed Service Agreements and we will call you for your HVAC maintenance, so it is something less to remember. Our Service Maintenance Agreements provide many benefits. Special discounts and additional warranty on parts, and peace of mind.
If your car was used as often as your furnace and air conditioner, it would have traveled over 200,000 miles in a year. Impossible you say? Well, it's not. Your home heating and cooling system operates approximately 3,200 hours in a year. If you traveled 3,200 hours at 65 mph in your car you would have changed your oil 66 times, used 4 sets of tires, performed 4 tune-ups and flushed your cooling system 3 times. No one would drive that many miles without performing any maintenance and expect for things to function properly. Just like your car, your Furnace and AC needs a tune-up, inspection and cleaning. By performing a precision tune-up on your furnace and AC you minimize the chance of breakdowns - saving energy and extending the life of your system. Preventive Maintenance and your Warranty
Every furnace and air conditioner manufacturer recommends routine maintenance. What many homeowners never realize or don't know is that nearly every manufacturers owner's manual and warranty fine print states the homeowner is required to maintain their equipment at least once a year or the warranty may become void. The small investment in a furnace tune-up will return big rewards. Some manufacturers require proof of routine maintenance, so remember to always keep a copy of your receipts for any and all service work performed. Don't wait much longer and call us today.
Service, Repair and Installation
There are air conditioning and heating manufacturers that put quality into their heating and air conditioning equipment. Regardless of that, the air conditioner or furnace is prone to breakdown. Because, it is a mechanical/electrical device and will need repair sometime throughout its wonderful and useful life.
Most of the time diagnosing problem is simple and other times it can be a complicated process where the HVAC technician calls in another HVAC technician or even an HVAC manufacturer representative. Residential and commercial heating and cooling is very important and you want the best possible air conditioning and heating service. It does not matter whether you have a Rheem, Trane, Carrier or other Air Conditioner and Furnace, and need a replacement whatever the manufacturer, it is best to get a qualified, NATE certified technician to inspect your system before a decision is made, if it should be repaired or replaced.
Once a diagnosis is made to your air conditioning and/or heating system, the unit can be repaired, in most situations, with stock HVAC parts off the truck. Sometimes the HVAC part has to be ordered because it is a specialty part that only the HVAC manufacturer of your equipment can provide. It is practically impossible to carry every single HVAC part for every single HVAC breakdown that occurs.
Air conditioning and heating maintenance, provided on a regular schedule, can prevent many air conditioner or heater breakdowns thereby preventing the need for you to call an air conditioning and heating repair person for air conditioner or furnace troubleshooting. Maintenance can save you lots of money in the long run but even so, problems can still occur. The cost of service varies widely. Be aware though that sometimes the cheapest price for HVAC air conditioning and heating service and repair is not always the best way to go.
Your main concern should be getting knowledgeable HVAC service technicians, reliability, punctually, honesty, integrity, and guaranteed work.
Littleton Heating, Air Conditioning and Electrical guarantee the labor and part/s for a full Year.
Per hour service charges are not the only way companies charge their customers. There are also service companies that flat rate their services. Either way you pay, you want the service and troubleshooting done in a quick and efficient manner with a guarantee. New technology and government requirements and regulations are pushing manufacturers to build more energy efficient HVAC equipment.
January 2006 we observed the end of 10 SEER units with 13 SEER air conditioning units mandated by the government.
This only makes sense; however, with the higher efficiency there comes complexity in the technology engineered into the equipment. A problem can be difficult to troubleshoot and diagnose and may require more time than the lower efficiency, less complex units. While it should be rare to have problems occur with new equipment, it does happen. When it does, you want a good troubleshooter who is knowledgeable and can make the diagnosis and repair in a timely and efficient manner. That means you want that HVAC contractor who sends their technicians to HVAC technical seminars and factory sponsored training classes, continuing education. That can make the difference between solving the problem quickly and efficiently in hours or being frustrated waiting days or weeks to have the problem solved.
The myth that most people believe is that if you add more refrigerant to the unit it will cool better. This is only true if the evaporator coil is operating below freezing. The unit must have a balanced charge and usually only an HVAC professional can charge your unit properly. Another misconception about refrigerant is that the unit burns it up and it must be replaced from time to time. This is not true. The refrigerant loop is a closed system and barring any leaks the air conditioning system should never need any refrigerant. (same as your refrigerator).
Refrigerant leaks should be repaired for the following reasons:
Many refrigerants have been deemed hazardous to the atmosphere by the EPA and have either Ozone Depleting Potential (O.D.P.) and/or Global Warming Potential (G.W.P.) Low refrigerant charges hurt the efficiency of the unit. Low refrigerant charges take away from the life of the compressor. The compressor is cooled from the return of refrigerant vapor.
When there is a low charge there is fewer vapors to cool the compressor therefore it runs hotter. Any compressor (or electric motor for that matter) which runs above the recommended temperature range will have a shorter life span and cost more to operate. Typically refrigerant oil leaks out of the system at the leak point. Eventually, the oil level in your HVAC system will drop below safe levels and the compressor will size up from lack of proper lubrication.
The Refrigeration Loop is a closed system and refrigerant should never have to be added to the unit unless there is a leak. Most residential units use R-22 refrigerant. Prices of R-22 are rising every year as we get closer to the date when refrigerant manufacturers will no longer be able make R-22. Phase-out of R-22, an HCFC, begins in 2010 and expected to be complete by 2020.).
If your unit needs more than two pounds or charged more than once a year it is recommended you have a refrigerant leak check done to your system. You most likely have a serious refrigerant leak and it needs to be repaired. Leaking units do not operate efficiently; take their toll on the environment, and can cause serious HVAC mechanical problems in the future. A good HVAC service tech will attempt to find the refrigerant leak within the hour's air conditioning service you are paying for in addition to the refrigerant charge.
Finally, after the air conditioning unit has been properly charged, the unit should have a temperature difference between the return and supply minimum of 15° Fahrenheit (delta T). The range is generally an acceptable practice to determine if your air conditioning system is operating efficiently.
If you do not have this range of temperature differential with your air conditioning system then there are problems which need to be addressed whether it is bad duct or a mechanical or electrical issue causing the problem the unit is simply not providing the cooling it needs to provide to make you comfortable.
