How To Choose AC Contractors

Choosing the Best AC Contractor in San Diego, CA

HVAC contractors with good customer reviews may not be suitable for your purposes all the time. These professionals always have a busy workload, because companies and individuals regularly need their air conditioner units fixed, replaced or serviced.

Carry out some research and check how trustworthy an HVAC contractor is, prior to hiring them. Simply follow the advice below to select a dependable contractor.

Finding a Good Air Conditioning Contractor

Visit the ACCA (Air Conditioning Contractors of America) website. This non-profit agency consists of over 4000 businesses and 60,000 professionals in the energy services and indoor environment sectors. ACCA assists people who are searching for quality contractors, with its’ membership database of reputable companies. These companies are all highly regarded, with a proven track record of satisfied customers.

Angie’s List is another possibility. This consumer rating website allows anybody to check whether a contractor they intend to hire is reliable and delivers outstanding work. Businesses and services are marked on a spectrum of A to F. The reviews about them are in-depth and cover things like professionalism, price, and fulfilling contract deadlines, etc.

A further approach that frequently works better than online review platforms is asking people for referrals. You can ask your neighbors, buddies and work colleagues, who operate in the same industry as you or even your relatives. Most of the time, people who are in your social circle won’t give you false information.

The BBB (Better Business Bureau)

The BBB is extremely useful if you wish to research the customer ratings of HVAC contractors. The site indicates whether any complaints from customers have been received against the particular business. Get in touch with the BBB office nearest to you with any questions you have.

Key Paperwork for HVAC Service Providers

A license. Based on the location of your company, HVAC contractors might have to acquire a state license or a license issued by the county or municipality. Typically, state requirements will include exam certificates and proof of technical expertise in AC repair.

There’s a couple of websites you can visit to learn the rules in your state or find out if your chosen contractor is licensed. These are National Contractors and the Contractor’s License Reference Website.

Bonds. Surety bonds for contract licenses are required, as a safeguard against improper dealings, and as a type of monetary insurance – in the event that something goes wrong with the contract. This is mandatory to receive a license, so consult your local authority to find out the specific rules in your area. The amount of the bond varies from one state to another.

Compensation insurance for workers. This is required to safeguard against injuries suffered by workers who perform jobs on your premises.

HVAC Contractor Qualifications

The surety bond and license are key requirements; however, you should also ensure that a contractor has the required permits to carry out the work. Ask the contractor whether he has experience of repairing, maintaining or replacing your current system, to avoid technical issues or misunderstandings in the future.

If you intend to fit a new unit, thoroughly research different contractors to discover which ones have worked with that specific model or brand. A reputable contractor is someone who will happily explain the maintenance procedure to you. Over the long term, understanding how to carry out maintenance yourself will save you huge sums of cash.

The Agreement

From the outset, make sure that everything agreed is written down. Often, it is better to email a business rather than telephoning them directly. This way, you will have a record of what was promised or said.

Do not depend on a promise. Ask for all bids or quotations to be given in writing. Then, you can store these away for future reference. After you sign an agreement, check that the document contains:

Information about what dates the job will be carried out

A comprehensive breakdown of equipment and labor costsair-conditioner

The due dates for payment

The project completion deadline


Request a few references from your heating, ventilation, and air conditioning contractor’s previous clients. Contact them and ask for their honest opinion about the contractor. Doing this will give you confidence that your choice of contractor will result in a smooth project for everyone concerned.

Final Thoughts

It is costly to install, maintain, fix or replace an air conditioner or furnace unit. Take heed of the above advice, to make wise choices and save yourself time and money.

Do not shy away from requesting copies of all relevant paperwork—like the insurance bond, license, or other official permits and certificates—even with contractors who come highly recommended.

Understanding Air Conditioner Problems

Understanding Air Conditioner Problems

Let’s look at why an air conditioner might stop emitting cold air. There are a number of things that can cause this problem, so it is important not to jump to conclusions. Make sure you do your due diligence and perform all the necessary checks before trying to fix the problem. The following information will point you in the right direction:


It Does not Have Enough Refrigerant.

To discover whether your external air conditioner has enough gas in it, check the heat exchanger. Switch the air conditioner on and wait for several minutes. If the heat exchanger freezes up, this indicates there is too little gas. The exceptions to this rule are as follows:

-A malfunctioning external fan: Even if there is enough gas in your unit, a malfunctioning external fan will make it freeze up.

-The output of air from the external fan is poor: Your external fan might function, however, it might not emit much cold air (heat pumps work as condensers in some internal units, and as evaporators in external units – this is what causes ‘freezing’ to occur). Inspect the fans closely to ensure that the air output is good.

 -The unit is defrosting itself: External air conditioners have settings designed to prevent freezing. If any freezing is detected, the electronic board performs a cycle inversion temporarily, delivering warm gas to the heat exchanger. This unfreezes the exchanger and removes any ice that has formed. After several minutes, the machine will start operating again. This process will fail to complete if the machine is switched off too soon. In this situation, the process will resume when you next switch on the machine, regardless of how frozen it is – and it will continue until completion. One way to stop this from happening repeatedly is to unplug the machine for five minutes to wipe the electronic board’s memory.

Another method to discover whether your machine is low on gas is to touch its’ copper pipe connections. While the heat pump is operating, these connections become hot. If there is not enough gas, though, they will feel much cooler — although this varies, based on the amount of gas still present.

Dirty Filters on Internal air Conditioners

If you are unfamiliar with filter cleaning, we can explain how it’s done. This is an important task because dirty filters stop air conditioners from heating up the air. In addition, they reduce the output of air from these machines, which prevents them from keeping rooms at a comfortable temperature. This can cause the gas pressure to rise inside the machines, and potentially trigger the pressostat, which shuts them off and increases their energy use while in operation.

If you can not access the filters on your air conditioner, check whether enough air is passing through it, and feel how warm the air is. If you only detect a small amount of hot air, the problem is probably just dirty filters, rather than a lack of gas.

The fan or Heat Exchanger is Dirty.

This is similar to the situation with dirty filters. Your air conditioner will not function correctly if the fan or heat exchanger is dirty. The signs are identical to what occurs with dirty filters. Your machine will produce hot air; however, it will only emit air softly.

The Cold Exchanger is Dirty

The cold exchanger on your air conditioner might have become dirty. If this has happened, you will notice that your unit runs OK initially; however, it will generate smaller and smaller amounts of heat over time. This might occur if some of the cold air doesn’t get released like it should be. In this scenario, the external unit can freeze, which causes similar symptoms to when there is a lack of gas.

A Malfunctioning External fan

Here, the symptoms resemble the ones that occur with a dirty, cold exchanger, however, they will occur quickly and be more pronounced.

A Malfunctioning Compressor

One tip from a local company ( says, “An air conditioner will not be able to generate hot air if the compressor malfunctions. This problem might arise if something goes wrong with the condenser unit or electronic board. In such a situation, the best course of action is to contact the SAT to find out where the fault originated.”

Air conditioners are tricky appliances to work with because they have many moving parts. When something goes wrong, it can be difficult to identify the cause if you are not technically minded. Many people misinterpret the symptoms they see and end up misdiagnosing the faults. The above information should help you to determine the underlying problems with your machine, so you can take the appropriate action to fix them. Suffice to say; if you are in any doubt, it is wise to call a professional.
