A good running HVAC system is a key feature to any home, so it is vital that this piece of equipment is properly maintained. Serviced units tend to run efficiently and smoothly for longer periods of times, saving homeowners money over the life of their HVAC system. The following article discusses what you need to know about HVAC systems.

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.

As the trees around your home lose leaves, it can cause your HVAC unit trouble. Frequently clean the fan grill when trees are shedding leaves. An obstruction, such as a leaf, prevents the maximum amount of cool air from entering the system.

When selecting the spot to put the outdoor compressor for your unit, choose somewhere that gets plenty of shade. The cooler the air which goes in, the less work the unit will have to do.

The correct HVAC system should have sealed air ducts to minimize heating or cooling loss as air travels to different rooms. The heating or cooling requirements of different rooms in the home should be taken into consideration. There is no reason to increase energy usage by controlling the temperature in rooms that are used very little.

If possible, your single pane windows should be replaced with double-paned ones. Having double pane windows allows your air conditioning unit to be run much less during the summer, because the cool air is kept inside the home. It also facilitates heat retention in winter.

An investment in a smart thermostat is truly going to save you money. You can program it to turn on and off at certain temperatures or times, allowing you to ensure that your air conditioner or heater isn’t running when it doesn’t need to be, saving you a ton.

Manage the heat flow into your home with window coverings to help out your HVAC system. In the warmer months, use drapes, curtains and blinds to block out sunward facing windows to keep heat from building up through the greenhouse effect. Alternatively, make sure that sunlit windows are letting light and warmth in during the colder months.

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.

Your HVAC helps you to stay comfortable in your home. Fortunately the tips above can help you avoid expensive repairs. If you don’t follow them, you won’t find any benefit, so keep that in mind.
