If you want to keep your air conditioning unit running efficiently, make sure you replace or clean the air filter once a month. Check the owner’s manual on the a/c for instructions on how to clean the filter. Never run the unit when the filter is removed and let the filter dry before reinstallling it.

Do not be surprised if the HVAC contractor you choose does an evaluation on your home. Any good contractor will spend time looking at the system you currently have and what the needs are for your home. They will also take a look at your duct system and look for air leaks.

Make sure you ask for an estimate in writing before choosing a specific HVAC vendor. There are a lot of moving pieces when it comes to purchasing these big items. You’ll want to compare not only the cost of the equipment, but also the set up and the overall energy costs.

Make sure the equipment you are buying is ENERGY STAR compliant. It may seem a small thing, but it isn’t. Products that are ENERGY STAR compliant can save you a lot of money in energy costs over the year. It can be over $100 easily, sometimes a lot more.

Whenever possible, try to shade the compressor unit outside. The air that’s in a place that is shaded is usually five to six degrees cooler than the surrounding air. Your air conditioning unit will be up to ten percent more efficient if it is properly shaded during the summer months.

Be sure to check your evaporator coil drains frequently when your air conditioner is running. If this tube backs up, you can find water damage to your walls, ceilings and floors. If you end up with mold just use a solution of bleach and water to clean out the tube.

Prior to hiring any HVAC contractor, you should ask how long their business has operated. Companies that are around awhile have a better record than those that haven’t been. Hiring an inexperienced contractor can be risky.

Make sure that the HVAC contractor you plan to hire does not use subcontractors to do their work. Many people use this as an excuse to shirk their responsibility in the event that something goes wrong when your system is being worked on. Only allow this if there is a note in the contract about what will happen if there is an issue.

Get an estimate before agreeing to have any work done on your HVAC unit. This will help keep you from being surprised by a bill at the end. Any reputable technician should be able to look at your unit, determine the problem and give you an estimate as to how much it will cost to fix it.

Turn to online reviews if you’re not sure how you should hire to perform HVAC maintenance. There are many sites that other customers can place their reviews. This is a good way to locate contractors that do good work and ones that are poor.

It’s easy to see that HVAC isn’t hard to get into if you just take your time with it. In the end, you won’t have too much trouble if you put what you’ve learned here to good use. Don’t take our word for it and give it a try yourself before you do anything else!
