You can ask any company to supply evidence of general liability professional insurance coverage. Any business that is not happy to provide proof of general liability (GL) insurance coverage should be prevented. A minimum standard for GL insurance is $1 million for domestic work and $2 million for light commercial.
There are other approaches for researching a/c, heating and ventilation companies such as: call your regional Better Business Bereau (BBB), carry out online searches and evaluations and ask the company in question for references. However, all of these techniques disappoint extensive openness. The BBB really works for the business it represents as they are just ranked if the business in question pays them a recurring fee. Online evaluation sites rarely show all of the evaluations got, and post evaluations from sources that are not always trustworthy. This provides a platform for companies to post their own evaluations and individuals to quickly post reviews without the business in question's capability to professionally solve the concern. Furthermore, no company would offer a negative recommendation; only those that are very positive. None of these are perfect dynamics for consumers looking for entirely unbiased evaluations and referrals. It is encouraged to utilize these methods as an informed customer and consider the details source for what it deserves.
Among the very best methods to find a brand-new air conditioning, heating and ventilation professional is through the "word-of-mouth" approach. If the company advised was inexpensive, professional and trusted for a good friend or relative, there is a likelihood that business will do the same for you. Excellent business utilize the word-of-mouth technique to constantly supply a new consumer stream by keeping their customers happy.
Other standard approaches for finding a new air conditioning, heating and ventilation professional include performing online searches, phonebook directory sites or online directory sites and other advertisement mediums. Keep in mind that all of these methods are purchased and paid for by the business in question. None of these approaches ought to serve as a review and ought to be used just as finding sources.
3rd party service providers such as Angie's list, Find Regional and other online companies are the newest platforms for sourcing and ranking cooling, heating and ventilating business. Although these companies do supply a service with some benefit, they are, in truth, including cost to the consumer. Angie's List, along with some other online organisation directory sites, charge the client directly for their scores and companies' contact info. Other third-party websites supply consumers with cooling, heating and ventilation business and include the cost of being a middle-man to the organisation formula. Bear in mind that none of these are "complimentary" and that customers should understand the expense and worth of using entities like these.
Several quotes are suggest when working with an a/c and heating specialist. There are no market requirements for rates HVAC associated product or service. Comparable tasks can vary countless dollars from one company to the next. A minimum of 3 estimates is recommended prior to the repair work or replacement of any major a/c and or heating system element and before the style and setup of new systems.
A second viewpoint can be of worth if the repair work or replacement is costly. Not all technicians or companies are equivalent or reliable. Fixing a/c and heating systems is extremely complicated. It is not uncommon for a repair work specialist to be unable to isolate the problem or for an agent to recommend an unneeded purchases. Calling a completing a/c and heating business can conserve money and time and regret.

Frequently Asked Questions:
What Would An Approximate Cost Be To Add Air Conditioning To A 2000 Square Foot House?
The House Already Has A Forced Air Heating System So No New Vents Would Need To Be Added.
It takes more info than just the square footage of the home. First you need to know the size of the unit. This is found through a process known as load calculation. Then you need to decide what efficiency and the added features you want in the unit because that affects the price. Then you can compare brands to find the best value. You can find all of this info at my source.
Fresh Air In Summer Vs Winter?
In Summer When Windows Are Closed For Air Conditioning, The Air Seems To Get Stale Faster, And After A Few Days, If The Outdoor Temperature Goes Down Enough To Turn Off The A/C And Open The Windows, It Makes A Lot Of Difference To How Fresh The Air Seems. But, In Winter, When The Windows Are Closed For Heating, The Air Doesn'T Seem To Get Stale As Fast, And When It Warms Enough Outside To Open The Windows For A Few Hours, It Doesn'T Make As Much Difference As It Does In Summer.
Why Is That? What'S Different Between Winter And Summer, That Causes The Indoor Air To Get Stale Faster In Summer?
Well, it depends on what you mean by the air being "stale." It is a rather subjective impression. But what may be the cause you feel like it, is this:
The warmer it is, the more moisture the air can contain. If you warm up a parcel of air, its relative humidity sinks. During the summer, for the same relative humidity outside, there is more moisture in the air. As that air enters your A/C, it cools down, thus bringing it to dew point temperature, which means, 100 percent relative humidity. As you know, A/C units produce water that must be drained. That water is the condensation of saturated air.
During the winter, when the house is heated, the air outside can be 100 percent relative humidity but once warmed up, it drops to a quite dry air. Here are some example with temperatures that I remember the absolute humidity by heart.
If a cubic meter of air at 0 C is entirely saturated, it contains 5 grams of water. At 15 C, it can contain 13 grams. If I warm up that air, the relative humidity will drop from 100 percent to 5 / 13 * 100 = 38 percent and that is very dry air!
So, your perception of "stale" air is in its relative humidity. High relative humidity helps the growth of fungi and bacteria.It also reduces the evaporation of our sweat that that is why a hot humid climate feels unpleasant. Sweating is our body's way of controlling heat. Evaporation takes latent heat energy.
How Much Does Air Conditioning And Heating Cost To Buy And Install?
Our Home Is 11 Years Old, And Everything Functions Well. I Am Not Thrilled About Our Utility Costs So Was Wondering How Much It Costs To Replace Existing System With New, Energy Efficient Systems. House 2100 Sq.Ft.
Looks like a system of about 5 tons (60 kBtu) in capacity if you go by the rule of thumb of 400 sq. ft. / ton. This will vary depending on weather region, window area, other internal heat loads and amount of insulation your home has. My guess is that you have a system that may be rated as SEER 8 or 10 because of its age. You'll want to look at a new system that has a SEER 13 (Federal minimum standard) or greater. A new unit with a SEER 13 will save about 23% on energy costs when compared to the old unit (SEER 10). The savings could be higher (about 38%) if the old unit has a SEER 8.
Make sure the new compressor is properly matched to the coils to ensure you get the correct SEER ratings. Otherwise mismatched coils may decrease the rating somewhat and the system not operate at its optimum performance. Fan flow (cfm) of the air handler is an important factor when considering SEER ratings along with the system being properly charged with refrigerant. If the new and old system does not have the proper air flow or refrigerant charge, your system won't operate according to specifications.
You need to see if the old system is properly charged and the coils are clean. This could be another huge cause for excessive energy use. It's a cheap fix provided their aren't any leaks in coils.
I first suggest you treat the building envelope for air infiltration (weather stripping, outlet gaskets, seal plumbing penetrations etc.) and seal the ducts before going to the big expense of buying a new AC system. Leaky ducts can account for 30%-40% of conditioned air being lost into attic or other unconditioned spaces. To find the leaks, testing would be done through the use of a blower door and Duct blaster. Your local utility may be able to do this for you for free. You can also contact a HERS Rater to do this. The small investment for testing and sealing up leaks could possibly solve your energy use problems without going to a lot of expense by replacing the existing system that has about 50% of it service life remaining. If the electric bills don't go down, then look at a more efficient system. Work from the cheapest solution to the most expensive.
To figure out how much energy your AC is using, take your three highest monthly bills (summer months) and average the energy (kWh) use, then take the lowest three months of energy use (winter months) and average those months as well. Subtract the winter months average from the Summer months average. The difference between the two figures is a good indication of how much energy your air conditioning is using.
To find AC operational cost, divide the average summer bill (dollars) by the average summer kWh. This will give you an average $/kWh. Multiply the average $/kWh times the difference between the summer average kWh and winter kWh. This will be an approximate of how much your air conditioning costs to operate:
Cost could run as low as $3,700 to $5,500 depending on who does the work, brand and required work to install; provided existing duct and electrical service are in good shape.
Do I Have Air Conditioning Or Just Heat?
I Have A Knob Thermostat In My Room. The Settings Go From Lo (Which Is Off) To 50 And All The Way To 90 Through Increments Of Ten.
It Is Pretty Hot In My Room To Begin With As It Is In The Middle Of Summer But When I Put The Thermostat To 60 Or So, Hot Air Comes Out.
There Is Nothing On The Actual Fan/Vent That I Can Push. Maybe My System Is Just Heat? I'M Not Sure Because 50 Seems Like It Would Be Pretty Cool, But Maybe The Numbers Don'T Signify Temperature?
Not Sure What'S Going On Here.
It's hard to tell just your thermostat. Lot's of times people will install a stat that works for both heat and a/c on a +heat only+ system (just because they're easier to find). Look outside for a condensor (usually round and blows hot air out the top - when it's on). If you have on of those, at some point you had a/c - if it's blowing hot air out the top, you have a/c. Another way to check, is to look for copper lines at your furnace - an indication of an a/c system. Air-conditioning systems are almost always hooked up to furnaces in residential homes (because they use the same blower to make the air circulate). Some homes have a "Package-Uint" on the roof, which has everything inside if it. It will be hard for you to figure out if you have a Package-Unit +without air-conditioning+, but it's unlikely you do, as they don't normally install them in residential applications. The numbers on your thermostat are temp. indicators, but sometimes they're off or just stop working altogether.
A 4 Ton Air Conditioning System That Requires An Input Power Of 5 Kw Would Have An Energy Efficiency Ratio Of ?
Well one ton of air conditioning is equal to 3.504 kilowatts. So 4 tons of ac would be equal to 14 kw. So your efficiency would be 14/5=280 percent.
