What Temperature Should I Set on My Thermostat?
The ideal temperature to set on your thermostat will vary by season.
In the summer, it’s recommended that you set your thermostat between 70˚ and 75˚ while you’re at home. When you’re away from home, setting the thermostat nearer to 80˚ can save energy, which will save you money on cooling bills.
In the winter, it’s recommended that you set your thermostat between 65˚ and 70˚ while you’re at home. When you aren’t at home, set it about 5˚ lower to save energy and money.
One of the best ways to easily control your thermostat settings and energy use is with our state-of-the-art smart thermostats.
What Size HVAC System Do I Need?
The best size for your new HVAC system will depend on a number of factors, like:
- The size and layout of your home
- The number of windows and doors your home has
- The cooling load required to meet your comfort needs
The best way to ensure you select a perfectly sized HVAC system for your home and needs is to work with an expert at National Heating and Air Conditioning. Our experts will work closely with you to determine the right size system—and we can handle the complete installation process.
How Long Does An Air Conditioner Last?
The lifespan of an AC system will depend on various factors, like:
- The type, brand, and model of the system you have
- Whether the system was installed properly
- How frequently it’s used
- How often it receives maintenance service
On average, air conditioners can last about 10 to 15 years. The best way to prolong the lifespan of any AC system is to make sure it:
- Is properly installed by trained professionals
- Receives regular maintenance at least twice a year
How Often Should I Schedule AC Maintenance?
We recommend air conditioner maintenance service at least twice a year, once before you turn your system on for spring or summer and again before you shut your system down in fall or winter.
If anyone in your family has respiratory issues or a compromised immune system, more frequent AC maintenance service may be better for you.
When you get regular air conditioner maintenance, you’ll keep your system operating in peak condition, which can prolong its life and save you money in the long run. It can also ensure optimal indoor air quality so you and your family can breathe easier season after season
Why Is My AC Making Odd Noises?
When you notice strange noises coming from your cooling system, take that as a red flag that something’s wrong. Some common noises that ACs make when they need repairs include:
These sounds can indicate anything from loose components to electrical problems, refrigerant leaks, and more. So, if you start hearing weird noises from your AC, call for professional AC repair service ASAP.
My house is cold. Do I need a larger furnace?
There are many causes for a house being uncomfortably cold in the winter, and there are at least as many solutions. Typically, a cold house is a drafty house with significant air leakage and insufficient insulation. Sometimes it can be caused by a leaky duct system or a poorly performing furnace. The experts at National Heating and AC can help you determine the exact cause of discomfort in your home, and offer the most cost effective solution to solve it.
Is it possible to manage my home’s energy consumption from a smartphone?
Breakthrough technology over the last few years has made it possible to monitor and manage your home or building’s energy consumption via WiFi, allowing you to view your home’s energy use in real time and even turn devices on and off. It is even possible to manage energy use using your smartphone!
Do I Need my Ducts Cleaned?
Experts do not recommend duct cleaning as an effective way to improve indoor air quality. This is because the bulk of dust and other indoor air contaminants that enter your home through your duct system actually come from the crawlspace, attic and walls. Leaky ducts allow this dust to enter the duct system, where it is delivered into the buiding’s living space. With Aeroseal, these leaks are eliminated, and any existing dust or debris existing within the duct system is eradicated through your HVAC system’s filters. Cleaning your ducts is necessary only in a few extreme cases, such as rodent infestation or if ducts are sufficiently clogged to prevent adequate airflow.
