Mike and his crew were fabulous to work with — patiently answered my hundreds of questions about a new furnace and its installation in my house. They worked very hard to make sure we were happy with everything. Installation was tricky in our house and Mike went above and beyond to make sure I was happy with how the venting system looked on the outside of my house. He is always quickly available by phone or email and happy to answer any questions…No reservations in recommending DeZiel Heating & Air Conditioning at all! . AAAAAA+++++

How often should I service my HVAC system?

Your heating and air conditioning system should be professionally inspected, cleaned, and serviced at least once a year. At DeZiel Heating & A/C, Inc., we recommend that you have your heating system – whether it’s a furnace, boiler, or heat pump – checked in the summer or fall, and your air conditioner checked in the spring. Throughout the year, make sure you change your air filter every 30 to 90 days and keep all HVAC units clear of debris.

What happens when I need a repair on a holiday or weekend?

Not to worry! The HVAC experts at DeZiel Heating & A/C, Inc. are available 24/7/365 to help with any and all of your heating or cooling emergencies. Did your water furnace break down on Thanksgiving?

They will arrive promptly, assess the situation, provide an upfront estimate, and get to work as soon as you approve. Our goal is to keep your family or business comfortable all year round, so call us the moment you need us and we’ll be there!

Which HVAC system is right for my home?

Deciding which HVAC system is right for your home can seem overwhelming.  But here are a few things to keep in mind that could make choosing a heating and cooling system a little easier.

  • Consider the size of your home – If your air conditioner and heater are too small for your house, they’ll have to work extra hard to cool and heat your space. But an HVAC system that is to large will heat or cool your home too quickly and keep cycling over and over again. Both situations cause problems for the units – and your utility bills. That’s why we will do what’s call a “load calculation,” which helps us determine the perfect system size of your home.
  • Think about the energy efficiency level you desire – The best thing about high-efficiency air conditioners and heaters is that since they use less energy, not only are they environmentally friendly, they help you save money.
  • Keep your budget in mind – Remember that you need to consider the cost of operating your HVAC system as well as the initial cost of the unit. Just because an air conditioner, for example, is inexpensive, doesn’t mean it will cost you less in the long run.

The heating and cooling pros at DeZiel Heating & A/C, Inc. are always available to help if you have any questions about choosing an air conditioner, furnace, boiler, or heat pump. We love helping our customers make the best decision for their needs.
