We have been using One Hour Heating to maintain our furnace and A/C for years. Gerald was prompt, courteous and only did the work that was required to keep our system in good operating condition. He didn't try to sell us options that we didn't need.

Determined that the water heater element had burned out so instead of replacing the entire unit, he just replaced the defective heating element, thereby saving me another $200.00 or more.

Was concerned something was wrong with our heating unit during a cold spell. They came out quickly, checked the unit and assured us all was well. Suggestions were even given regarding insulation. We have used Air Experts before and will use them in the future

Heating Oil questions, answered by experts

Yes, geothermal heat pumps are worth the money. You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system. Over time, your savings on monthly utilities will pay for the cost of the geothermal heat pump installation. If you have an incredibly small yard, however, you may not have enough space for this type of system.

Costs depend on system age, type, labor, and whether part replacements are necessary.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt.

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.
