​HVAC Replacement:

​Q: What is the average life expectancy of a system?

A: Most systems have a lifetime of 10 to 20 years. As your equipment gets older, its efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. When a unit begins to show its age, you have two choices: You can overhaul the system or replace it. Because heating and cooling technologies improve over time, a new system with more energy efficient equipment makes sense, especially if your system is 7 or more years old. 

Q: How can I reduce my energy costs?

A: Here are some suggestions that can help you reduce your energy costs:

    *Upgrade to a high-efficiency system - Swapping your old, inefficient air conditioning system for a high-efficiency one can cut electricity bills by up to one third. 

    *Adjust the temperature- Typically, adjusting temperatures 5-8 degrees (down in the winter and up in the summer) can help save energy if you're going to be away from the home for several hours.

     *Install ceiling fans - Change the direction of airflow on your ceiling fans. In the summer, the blades should operate in a counter-clockwise direction. In  the winter, the blades should be operating in a clockwise direction helping to push the warm air from the ceiling down in to the room. 

     *Have annual maintenance performed - Tuning up your cooling system each spring and your heating system each fall will help ensure each operates at peak efficiency and can help you identify and resolve any potential issues before a break down occurs. 

     *Don't block vents in well-used rooms - Keep your supply and return vents free of objects like blinds, carpets or furniture so your air conditioner can operate efficiently and there is even, cool air distribution. 

     *Close vents in less-used rooms - By closing vents, you won't be spending money cooling or heating rooms that are used less. 

    *Install a programmable thermostat - A programmable thermostat enables you to control your home's temperature when you're away or asleep. For every 1 degree you lower your thermostat for seven hours per day, you can save approximately one percent on your heating bill. 

Q: Will a bigger system perform better?

A: No, you don't want your air conditioner to be too large. Air conditioners control the comfort level in your home by cooling the air and by removing humidity. An over sized air conditioner can cool your home faster, but it will use more energy and will not remove humidity adequately. In addition, your existing duct work may not be able to support the airflow of a larger system.

​A unit that is too large for your home will have short run cycles. it can take only a short time to cool the air, but the unit shuts off before enough air blows across the indoor coil where moisture condenses into water and drains from your system. Too much moisture left in the air can lead to mold and mildew problems. These short run cycles also mean your system starts and stops more often which uses more energy and cause more wear and tear. An air conditioner runs more efficiently during long run cycles. 

The same holds true with heating systems. An over sized furnace can warm the house quicker, but it uses more fuel and causes greater temperature swings in the home.

Q: How do I know if I need a new heating and cooling unit instead of simply repairing my current one?

A: If your unit is seven years old or older, requires frequent repairs or stops working, fails to heat or cool areas of your home, runs excessively or constantly turns on and off, or produces high utility bills, it can be more economical to replace your existing system. We can send one of our Comfort Specialists to your home to examine your home inside and out to determine the right system for your needs or to see if your old system is just in need of a repair or two. Many homeowners assume that a new HVAC system will solve their problems, and sometimes that is the case, but frequently there are underlying issues that need to be addressed simultaneously to achieve the kinds of efficiencies possible with possible with a new unit.

Q: Can you give me a price without an in-home consultation?

A: No, we cannot provide a quote over the phone, as pricing varies based on your needs and the unique conditions in your home. In order t o properly size your system, a detailed load calculation must be performed by a quality technician. Installing an over-sized or undersized unit may result in higher utility bills and your system may not heat or cool at capacity. 

​Q: How do I know which HVAC system is right for my home?

A: To properly size an HVAC system, you will need to have a detailed load calculation and evaluation of your home performed. This service is included when you call and schedule your in-home consultation with one of our highly trained Comfort Specialist.

Q: What brands do you install?

A: We offer Trane, Goodman, Rheem, Lennox, Ruud, and Carrier.

Q: Can I just replace the outdoor unit on an older air conditioning system to save money?

A: While it may cost less initially to replace the outdoor unit on an older system, over time utility expenses will add up and may even cost you more. Replacing only the outdoor unit will lower the efficiency of the unit. Even worse, your system may fail sooner than normal and most manufacturers' warranties will be voided. You should always replace the indoor cooling coil with the outdoor unit. 

Q: Do I need to have my duct work replaced?

A: Industry experts estimate that as many as 70% of all homes with central air have poorly installed duct work. Ducts that are not properly sealed or insulated fail to get the hot or cool air where you want it efficiently, therfore costing you money. Before you invest in a new system, make sure an HVAC expert checks your ducts and includes specific recommendations in their proposal to you. It is standard procedure for your duct work to be thoroughly examined during your in-home consultation with Central Sun Heating & Air, llc.  Don't spend money on a new, super-efficient system unless you are sure those efficiency gains won't be lost by poor duct work. 

Q: Will I need a permit?

A: Permit requirements vary by location. Some municipalities do require a permit. If a permit is required, Central Sun Heating & Air, llc will obtain the proper permits needed for your home. 

Q: What are the advantages of equipment with variable speed fans?

A: Variable speed fans operate on a simple principle: they are able to spin at different speeds depending on the heating and cooling needs of your home. Usually, they operate at lower speeds, delivering a steady, reliable stream of warm or cool air to your home. When conditions become more extreme, the fan speed increases so that the system can meet increased demand, guaranteeing that on even the hottest days or coldest nights, your comfort needs will be met. Older systems simply switch on or off. Newer, variable speed systems lower your utility bills by only using the energy needed to heat or cool your home at any given time. 

HVAC Maintenance:


Q: When do I need to have my unit serviced?

A: You should have a regular tune-up twice a year -- typically at the beginning of spring and fall -- to ensure that your system is working efficiently before the weather gets too hot or too cold. However, HVAC maintenance may be scheduled at any time. 

Q: Is a tune-up covered by my warranty?

A: No. Extended warranties and extended service agreements ​DO NOT cover the cost of regular maintenance of your system. Tune-ups are considered regular maintenance and are Required By Most manufacturers for your warranty to remain in effect.
