1) Tell us a little bit about your company and the services you offer.
We are a heating and air conditioning company that specializes in service and replacement. We have been in business since 1989. Blinson Service Company has thousands of customers in Wake, Durham, and Johnston county. Our services extend beyond HVAC service and installation. We also perform mold inspections, radon testing, duct air tightness testing, whole house infiltration testing, vapor barriers, radiant barriers, and crawl space encapsulation.
2) What are some of the most signs that your HVAC system needs to be repaired?
Listen to your system. In many cases, you may hear a change in the sound of the system when it is running. If the system is running in the cooling system, you should be able to see water draining from the drain pipe where it exits the foundation wall. If you have a unit in your attic, there should be a safety drain pan under it. It should never have water in it. If you see water, there is a problem and needs to be diagnosed before you have a potential water leak though your ceiling. If you see ice forming anywhere around your unit in the cooling season, there is a problem and needs to be diagnosed.
3) When would you suggest that homeowners consider replacing it instead of repairing?
If your system is out of the manufacturer’s warranty period, and is 10 years or older, if there is a major repair such as a compressor, motor, or heat exchanger, this would be the time to consider a new system. If your system uses R-22 refrigerant and has leaks that cannot be repaired, this would be another reason to consider replacement with a system that uses the new EPA specified R-410a refrigerant.
4) Is there a time frame (or age) when you would usually recommend replacing heating and /or cooling equipment?
10-12 Years is the average life expectancy of major components of HVAC equipment. Most manufacturers do not have a warranty more than 10 years on parts.
5) Can you briefly talk about some of the benefits of getting a new heating, ventilation and air conditioning, or HVAC system?
If you have an HVAC system that is 10 years old or older, chances are the efficiency rating is 10 SEER (Seasonal Energy Efficiency Ratio), or less. The SEER rating of a unit is the cooling output during a typical cooling-season divided by the total electric energy input during the same period. The higher the unit’s SEER rating the more energy efficient it is. In the United States, the SEER is the ratio of cooling in British thermal unit (BTU) to the energy consumed in watt-hours. The minimum SEER rating established by the Environmental Protection Agency is 13, however beginning January 1, 2015 will change to 14 SEER.
6) Do you have tips for people who have a noisy HVAC system?
First of all, we need to find out where the noise is coming from. Is it the equipment or is it the duct system? In many cases, when we assess HVAC problems, we find that the duct work was improperly installed from the beginning. This can cause many different problems with the HVAC system such as insufficient air flow because the duct work is too small. This can lead to a pre-mature failure of a blower motor or compressor, and excessive noise in the duct system. Ductwork is a critical component of the HVAC system. It must be sized correctly so that you reap the benefits of an energy efficient system.
