Dealing with HVAC trouble can be a frightening scenario for anyone who is unfamiliar with the best ways to identify reputable, qualified contractors. The most important thing a homeowner can do is to educate themselves thoroughly on the process before any needs arise. The article below can help everyone do just that.

Before you hire anyone to do any work on your HVAC, be sure to get a written estimate which has itemized costs listed on it. This will ensure that comparing one contractor to another will be simple as you can see what one offers that another doesn’t, or what price they’re charging for the same items.

Clean the coils of your condenser fan each month. Before you clean the surface, be sure to turn off the power. Also, make sure you remove any debris or leaves from the condenser unit outside.

Don’t ever let your home temperature get dangerously high. An air conditioner can only cool your home by 20ºF quickly. If the temperature in your home rises to 100 degrees F or higher, cooling it will only drop the temperature to 80 degrees F. When you factor in humidity, this can still be dangerously hot for the human body at rest.

Clean your filters! If you have a window unit air conditioner, there will be a filter right under the grill you can vacuum. If you have a furnace or outdoor units, they will also have filters to be cleaned or replace. A dirty filter can make your unit inefficient or even let it overheat.

Consider all of your alternatives before installing a central air conditioner. You can only cool certain rooms, use whole-house fans, or even make use of a geothermal system. The more efficient the system you set up, the less you’ll spend on utility bills over time as you use it.

Prior to hiring any HVAC contractor, you should ask how long their business has operated. This gives you some history so that you can be sure the company is reliable. New companies are just too risky.

Use plants to increase your air conditioner’s effectiveness. An AC unit fully shaded by trees and shrubbery can operate up to 10 percent more efficiently. However, do keep spacing in mind. Air flow must not be constricted, and technicians need room to work when they come out to service your unit.

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.

There is no denying the fact that confronting issues with a HVAC system can be scary for those not in the know. Finding a great local contractor to install new equipment or repair the old can be a challenge without great tips and advice. Luckily, the information presented above can serve as an easy reference anyone can use.
