When do I know it's time to replace my system?
When the system starts giving you more problems than seem cost effective to fix, particularly when major components such as the compressor start making unusual noises or otherwise indicating need for a service call. When faced with major repairs, consult several contractors for their recommendations. Replacing a compressor is somewhat less expensive than replacing the entire unit, but new units may give you greater efficiency and lower operating costs in the long run.

What is involved in replacing an old system?
Aside from the placement of the new equipment, your dealer will inspect several items and make a determination of whether or not these items need to be supplied or replaced. Some of the items include: ductwork, insulation, refrigerant piping, electrical service, wiring, thermostat, condensate piping, flue piping, flue terminations, chimney liner, slabs, filters, driers, registers, grills, drain pans and evaporator coil.

Why should I replace my existing heating or air conditioning system?
You may wish to consider replacing your air-conditioning or heating system if it is old, inefficient, or in need of repair. Today's systems are as much as 60% more efficient than those systems manufactured as little as ten years ago. In addition, if not properly maintained, wear and tear on a system can reduce the actual or realized efficiency of the system. If you are concerned about utility bills or are faced with an expensive repair, you may want to consider replacing your system rather than enduring another costly season or paying to replace an expensive component. The utility cost savings of a new unit may provide an attractive return on your investment. If you plan on financing the purchase, the monthly savings on your utility bill should be considered when determining the actual monthly cost of replacing a system. The offsetting savings may permit you to purchase a more efficient system.

Why should I replace my working furnace or air conditioner?
Although your present furnace or air conditioner may be working, if it is more than 12 years old you should consider replacing it with a new high efficiency system. A new heating and air conditioning system could save up to 50 percent on energy costs, and save you money in the long run on heating repairs. While these products save you money on your utility bills, they also offer a better degree of comfort within your home.

I want to change my gas unit for a heatpump.
This is not a smart move. Gas produces more heat with less cost than electric heat in most parts of the USA. The purpose of a heatpump is to help reduce the costs of electric heat.

When is it time to replace your central heating and cooling system?
When your equipment needs frequent repairs and your energy bills are increasing. When your heat pump or air conditioner is more than 10 years old. Consider replacing it with a newer, more energy efficient equipment that meets the BGE rebate efficiency levels
When your furnace is more than 15 years old. Consider replacing it with a newer, more energy-efficient furnace that meets the BGE rebate efficiency levels.

Why should I have my equipment serviced?
Annual servicing includes cleaning the system, checking for any problems or potential problems and adjusting for Peak efficiency. The benefits include:
Increased dependability.
Find potential problems and fix them quickly.
Provide maximum efficiency which lowers energy costs.
Prolongs the life-span of the equipment.
Maintains safe and healthy operation.
Can help to protect the environment.
Drastically reduces the chance of a break-down which usually happens at night or on weekends when repair rates are higher.

How long have ductless systems been around?
Ductless heating and cooling systems were developed in Japan in the 1970’s and have since become a preferred heating and cooling system throughout Asia and much of Europe. In the United States ductless systems have been used in commercial applications for over 20 years.

Why is it important to have regular maintenance on my home comfort system?
You wouldn't buy a brand-new car and expect to never have to put air in the tires, change the oil and check out any unusual noises, would you? In the same way that an automobile requires periodic maintenance for optimal performance, a home comfort system should be regularly inspected by a qualified technician.

How often should I have my air ducts cleaned and inspected for repairs?
Yes, this is normal. A heat pump generally produces air tIn the majority of homes, cleaning and inspection once every three years is adequate. The type of air filter you are using and the frequency of maintenance on your heating and air conditioning equipment can have a significant effect on the duration between cleanings. The purchase of a good quality air cleaner will protect your heating and air conditioning equipment, duct system, and your home, while scheduled maintenance will extend the life of the equipment and increase its efficiency.hat is around 80° and provides even comfortable, heating around the house – not a blast of intense heat. However, 80° may feel cool to your hand, which is usually closer to 90°.

What maintenance should I do on my air conditioner?
The most important maintenance you can do is to change your filters regularly. Ground mounted outdoor units need to be kept clear of debris, clutter, weeds or landscaping that can grow too close and reduce the airflow to the unit. Also, keep pets away from the unit because pet urine can cause expensive damage. Use caution with a weed trimmer around the unit to prevent damage to the control wiring or to condenser coil fins. Any additional maintenance should only be performed by a qualified contractor.

Where do I get replacement parts?
Contact your dealer for help obtaining replacement parts.

How to Troubleshoot a Heat Pump?
To troubleshoot a heat pump, start by replacing filters and cleaning and lubricating its components. Make sure the metal cabinet of the pump is level. If a blown fuse has caused a pump to be off for more than an hour, you should operate it for 6-8 hours to keep it running properly.

Should I change my indoor coil?
When replacing your air conditioner or heat pump, the answer is most likely yes. The efficiency ratings that are advertised for an air conditioner or heat pump are based on the performance as part of a matched system. If only the outdoor portion is changed, the efficiency and savings could be less than that of a matched system.

What is General Energy use in Any AC ?
It should be noted that in a thermodynamically closed system, any energy input into the system that is being maintained at a set temperature (which is a standard mode of operation for modern air conditioners) requires that the energy removal rate from the air conditioner increase . This increase has the effect that for each unit of energy input into the system (say to power a light bulb in the closed system) requires the air conditioner to remove that energy. In order to do that the air conditioner must increase its consumption by the inverse of its efficiency times the input unit of energy. As an example presume that inside the closed system a 100 watt light bulb is activated, and the air conditioner has an efficiency of 200%. The air conditioner's energy consumption will increase by 50 watts to compensate for this, thus making the 100 W light bulb utilise a total of 150 W of energy.

What are the potential dangers of operating your HVAC system with a cracked heat exchanger?
If a crack in the heat exchanger allows carbon monoxide to escape into your home you may experience dizziness, light-headedness, flu-like symptoms, or even death by asphyxiation. Carbon monoxide limits the body’s ability to take in oxygen. This is an extremely dangerous situation to have in the home, because the effects of carbon monoxide poisoning may be gradual and undetected.
