Why should I purchase a new heating or air conditioning system?

If your system is old, in need of constant repair or simply not getting the job done, purchasing a new system will give you the comfort and reliability that your existing system is not providing. Investing in a new system today will help you save money tomorrow.

How can I find the right system?

Choose a new unit with equal or higher efficiency ratings compared to your previous system. There are many heating and air conditioning systems to choose from. The size and age of your home, number of rooms and climate zone are some of the factors that will help determine the type of HVAC system you need. Don’t forget that A Quality HVAC is just a phone call away! If you can’t decide which HVAC equipment to purchase, we will be happy to consult you.

What are the benefits of a geothermal system?

A geothermal HVAC system can help reduce your energy consumption and cut your electricity bill by as much as 60%-70%, depending on your current usage rates. By harvesting the energy from the depth of the earth, a geothermal system can both heat and cool your home more efficiently and evenly than a traditional furnace/AC combo. Another benefit is quiet operation and minimal carbon footprint.

How long will my system last?

When properly maintained and serviced, a gas furnace should last 20 to 25 years, and an air conditioner should last 12 to 15 years.

Why should I perform preventative maintenance?

By performing preventative maintenance or having your system serviced regularly, you can maximize the life of your heating or cooling unit. Your Maryland HVAC system works hard and almost year round with minimal breaks. Without seasonal servicing, parts may wear down faster and your system will lose its efficiency, which often leads to higher heating/cooling bills.

What is the most efficient way to run my heating or cooling system?

Keep your thermostat at a constant temperature. Change your filters every month. Keep your outside units clear of leaves, shrubs, grass clippings, etc. Have your unit serviced every spring.
