A bad HVAC is a real nightmare. After all, you probably want to know as much as you can about keeping your HVAC in proper working order, so this article can help. Then you're going to love the article below, which has plenty of helpful tips.
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.
Get any agreement with an HVAC contractor in writing. Some contractors try to skip over this step and charge customers a fortune. If you have a certain price and warranty in writing, they cannot go back and change this information. If they do, they could have a lawsuit on their hands.
When seeking a new contractor, ask loved ones for referrals. They'll often have already had someone in for similar work and will know who to trust and who to avoid. If your family hasn't used anyone, ask co-workers or other people you trust in your community for some references.
Be sure to get every quote or estimate in written form. You have no recourse on a verbal agreement, so a written contract is a must. This will allow you to follow up if something goes wrong or you don't get what you were promised, protecting you from shady contractors.
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.
