Frequently Asked Questions About D & D Heating & Air Conditioning Inc
What should I do to prepare for my service appointment?
To ensure your appointment goes smoothly, please clear the area around your heating or cooling equipment to provide our technicians with easy access. Make sure pets are secured in a separate room, and let us know about any specific concerns or issues you've noticed with your system. If you have maintenance records or warranty information available, having those on hand can be helpful.
Do you offer any guarantees or warranties for your work?
Yes, we stand behind the quality of our work with warranties on labor and parts. The specific terms depend on the type of service performed and the equipment installed. Our team will provide you with detailed warranty information for your particular service or installation, and we're always available to answer questions about coverage.
What products and services does D & D Heating & Air Conditioning Inc offer?
We provide comprehensive heating and cooling solutions for residential and commercial properties throughout Central Massachusetts. Our services include installation, repair, and maintenance of furnaces, air conditioners, heat pumps, and ductless systems. We also offer indoor air quality solutions, emergency repairs, seasonal tune-ups, and energy efficiency consultations to keep your home or business comfortable year-round.
How often should I schedule maintenance for my heating and/or cooling system?
Our experts recommend scheduling preventative maintenance at least once a year, especially before summer or winter as the fluctuations in temperature arrive. HVAC systems require consistent tune-ups and maintenance to make sure they last and continue to run optimally. According to Today's Homeowner, an HVAC system should be inspected twice per year.
What signs show that my HVAC system might need repairing?
Residential HVAC systems that may need servicing will often include unusual noises, inconsistent temperatures throughout your home, increased energy bills, and strange odors. If any of these are happening, it’s important to find a licensed HVAC technician and get it checked out.
Should I replace my existing HVAC system or try to repair it?
There are many factors that can influence this decision, such as the age of the unit, how often it is used, if regular maintenance has been performed, and more. Finding a reputable, licensed HVAC company to walk you through the options after inspecting your system is key. Generally speaking, our experts agree that HVAC systems over 15 years old that need to be fixed often should probably be replaced.
How can I improve the efficiency of my HVAC system?
Here at D & D Heating & Air Conditioning Inc, we suggest regular HVAC maintenance, changing air filters regularly, and keeping furniture away from vents to allow full air flow can all be factors in improving the efficiency of your heating or cooling.
Why is my furnace blowing cold air?
Your furnace, when set at a warm temperature, should never blow cold air and may be a sign of an issue. Possible issues could be a thermostat malfunction, being low on fuel, the pilot light not being on, or a clogged filter. It’s best to call someone for HVAC repair if you’ve addressed these issues and the problem continues.
What causes my furnace to make loud noises?
Your furnace should not be very loud, and if it is, we suggest contacting an HVAC company for a cleaning and/or maintenance check. Dirty burners, loose blower components, or failing bearings can all create loud noises in your furnace.
How can I improve the heating performance of my system?
Sealing air leaks in your existing HVAC ductwork is a solution. Make sure all vents are not obstructed, windows are locked, and a programmable thermostat is used.
Why isn't my air conditioner cooling my home to the temperature it’s set at?
This may be a sign of low refrigerant levels, dirty unit coils, a clogged condensate drain, or thermostat issues. If these issues have been addressed and the problem continues, it’s best to call a licensed HVAC company to investigate.
How often should I change my air conditioner filter?
In our experience, most air conditioning filters need changing every 1 to 3 months. This can depend on whether there are pets in the home and how often the unit is used.
