You can ask any company to provide proof of basic liability professional insurance. Any company that is not going to supply evidence of general liability (GL) insurance ought to be prevented. A minimum basic for GL insurance is $1 million for domestic work and $2 million for light business.
There are other approaches for looking into air conditioning, heating and ventilation business such as: contact your regional Better Business Bereau (BBB), perform online searches and reviews and ask the business in concern for references. However, all of these techniques disappoint detailed openness. The BBB actually works for the companies it represents as they are only ranked if the company in concern pays them a recurring cost. Online evaluation sites seldom display all the evaluations received, and post reviews from sources that are not constantly reputable. This offers a platform for business to post their own reviews and individuals to hastily publish evaluations without the business in concern's ability to expertly fix the concern. Additionally, no company would provide out a negative recommendation; just those that are incredibly favorable. None of these are ideal characteristics for consumers looking for completely unbiased evaluations and referrals. It is encouraged to use these techniques as an informed consumer and consider the details source for what it is worth.
Among the best methods to find a brand-new cooling, heating and ventilation contractor is by means of the "word-of-mouth" method. If the company recommended was inexpensive, professional and trustworthy for a pal or member of the family, there is a great chance that business will do the same for you. Great companies use the word-of-mouth technique to continuously supply a new customer stream by keeping their clients happy.
Other standard approaches for finding a brand-new air conditioning, heating and ventilation contractor include carrying out online searches, telephone directory directories or online directories and other ad mediums. Remember that of these approaches are bought and paid for by the companies in concern. None of these techniques should act as a testimonial and should be used only as locating sources.
3rd party companies such as Angie's list, Find Regional and other online business are the newest platforms for sourcing and ranking cooling, heating and ventilating companies. Although these companies do supply a service with some benefit, they are, in fact, including cost to the customer. Angie's List, as well as some other online organisation directories, charge the client directly for their rankings and business' contact info. Other third-party sites provide consumers with air conditioning, heating and ventilation companies and add the cost of being a middle-man to the company formula. Remember that none of these are "totally free" and that customers ought to understand the cost and value of using entities like these.
Multiple quotes are recommend when employing an air conditioning and heating professional. There are no industry requirements for pricing HEATING AND COOLING associated product or service. Comparable jobs can vary countless dollars from one business to the next. A minimum of three price quotes is advised prior to the repair or replacement of any major a/c and or heater part and prior to the style and setup of brand-new systems.
A 2nd opinion can be of value if the repair or replacement is pricey. Not all professionals or business are equivalent or respectable. Repairing a/c and heater is extremely complex. It is not unusual for a repair work specialist to be not able to isolate the problem or for a representative to recommend an unneeded purchases. Getting in touch with a contending a/c and heating business can save money and time and remorse.

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.
