Air Conditioning Maintenance - Air Conditioning Questions
1.10Any Air Conditioning experts out there?
Q.Hello. we are installing a Diesel Generator for running our house. We are off grid. We are buying a Cummins 15 KVA/12KW Prime Power Generator. This generator can supply 23 Amps per phase in the standby mode with a PF of .8
With the normal set up, we can run only 3, single phase 18,000 BTU ACs, one on each phase.
I read somewhere that by installing Power factor Capacitors, we can install more than one AC on each phase.
Do you know anything about that? Is it an easy task or do I need to get an engineering degree for this? I'm some what comfortable with doing electrical work and can do minor calculations as well.
Any help would be really appreciated.

A.HVAC Tech.: You need an electrical engineer to solve this problem as it does not fit into Heating, venting, or air-conditioning.
1.00Need air duct cleaning after 5 years without an air filter?
Q.My aunt has not cleaned their air ducts in 5 years(ever since they moved into the house) and they have not been using an air filter since. She lives in northern cali and uses the heater during the winter and the a/c not so much during the summer.
I saw the part where the air goes into the duct and it was covered with so much grey dust that i just HAD to vaccum it for her. There were 2 of these. They were both downstairs up close to the ceiling. Their house is 2 story. one was next to the stairs
I told them they should buy an air filter because her whole family has asthma including her, but they're scared that the filter might catch on fire!
Their youngest son (4) also just recently got asthma after winter.
But they dont really get allergies in the house in the summer because they have windows open but its only in the winter when they have the heater on
Dont you think they need this or is it just me?
Do you suggest air duct cleaning? since its been so long without a filter
A.To give you an idea of how much dirt is in the duct work you can look inside the ducts or supply air runs by removing the diffusers.
What you should be more concerned about is the dust that may be attached to the blower wheel and the evaporator coil and if the furnace is High efficiency it may have a secondary heat exchanger that may also plug up. If any of these actually plug right up with dust It may cause the air conditioning to freeze up. What is required is a full heating and cooling planned service maintenance check and cleaning. Many heating and cooling companies have a program in place and will go as called or will sign you up for an annual maintenance. The annual maintenance might be a good idea for them as they will also change the filter regularly. The usual cost of a maintenance program is what they would charge for 1 1/2 -2 hrs labour and any parts that you would need like a filter.

1.00How much to have the ducts cleaned and mold removed?
Q.I just moved into a new home that had never had the ducts cleaned. The house is a ranch with gas forced air heat on one zone with about 9 vents. I found this company on a coupon for $45 which included unlimited vents and a couple access holes. When the company began their work they found mold and the price skyrocketed from $45 to $1400. Does this sound like a screw job or is that price accurate for mold removal and duct cleaning?
A.Mold removal/remediation is entirely different from air duct cleaning. However, it is not uncommon to find mold in your air ducts. That is why we recommend the Electro Breeze Duct Mount UV kit at http://www.allergy-relief-air-purifier.com/air-conditioning-filters.html. This unit will eliminate mold and bacteria from your indoor air and keep your air conditioning coils clean from mold.
You must consider that to remove the mold from your air ducts, the air duct cleaning company is entering into a potentially dangerous situation for their employees. This requires expensive equipment and a person with the skills to do the remediation properly. Now that they have knocked the mold loose, you will need the high efficiency filtration and ultra-violet light of the Electro Breeze DMUV kit to kill and capture the mold spores in your indoor air. I hope this helps.
1.00How do you clean the air ducts in a car?
Q.My car is getting older and I've noticed the air coming from the air conditioning ducts and air vents smells musty, dusty, and dirty. Is there a way I can clean the ducts and vents? Also, is this something I can get done at an auto detailer?
A.The answer to your 2nd question first. Maybe?! Some detailers will only clean/restore what they can reach, although there are some who might go the extra mile. The problem is, they don't want to be responsible for destroying your dash vents to get at the ducts.
When I worked in a body shop, we simply used compressed air through the vents to blow out the dust and dirt accumulated while the car sat inside being worked on.......some people even put pieces of air freshner directly in the vents to sweeten the smell afterwards.
1.00House in warranty - is the builder responsible for cleaning air ducts if it is causing black stains on carpet?
A.That is considered maintenance, you are responsible for cleaning your own air ducts or having someone come do it for you.

1.00I see a lot of air particles, how can I clean the air vents?
Q.I see a lot of air particles floating in my bedroom, It is more noticeable when my hearter/furnace is running. I get a feeling my ventillation pipes ought to be cleaned somehow. Should I get the Pros to do it ? or Can I do it myself, I am lucky to be a new owner but I am cash strapped. My furnace is feuled by natural gas,. What should I do regarding heating and ventallation maintenance. Thank so much for your advice.
A.Have an HVAC company come out that specializes in duct cleaning. Most have cameras where you can see the dust. Or you can purchase a better filter, either pleated or washable. They trap more particles.

Maintenance
Air conditioning maintenance cannot only increase the efficiency of your unit, but also avoid the need for AC repairs, and increase the life span of your unit. It is estimated that in the absence of air conditioner maintenance, your AC will lose up to 5% of its cooling capacity each year. With regular central air conditioner maintenance however, you can keep your unit functioning at its original efficiency for years on. Lack of maintenance can drag down the efficiency of your system, leading to massive power bills. In fact, maintaining your AC is considered an important part of increasing the life span of your unit. As your filters get clogged and the heat absorbing capacity of your evaporator coil is impacted, you can expect the life span of your unit to reduce each year.
Air conditioning maintenance consists of a few preventive HVAC maintenance tips that can be performed at home. First of all, clean your air filters regularly or get them replaced. Air filters can quickly get blocked with dust particles, especially during the dry season, and this obstructs the air flow. It can also affect the evaporator coil. If your air conditioner has a reusable filter, simple cleaning will do, otherwise, it will need to be replaced. Air conditioning maintenance technicians recommend that you replace the filters at least every month. If your air conditioner is used heavily, or if it is dry and dusty season, the filters may need cleaning more often. Keep the outdoor condenser coil clean by removing leaves and other debris from the area. If there is any foliage at the back, get it trimmed to enable proper air flow. Your evaporator and condenser coil fins can be cleaned using a fin comb. Other central air conditioner maintenance includes making your ducts airtight. Your AC maintenance technician can seal your ducts, and can also insulate the ductwork, especially in areas like attics.
Most air conditioning maintenance contractors will offer annual maintenance contracts that involve a fixed price. You can also find discounted prices at specific times of the year. We can help you find qualified air conditioning maintenance contractors serving home owners in the Tulsa area.
