Salvador and his son came over and replaced TWO (!) water heaters—one in the main house and one in a guest house. I had bought the water heaters in advance. After he saw them, he told me that the new codes call for an “expansion tank” which helps the water heater last longer. He could either get...

I had a problem with the heater I purchased and they were very nice and easy to deal with. It was the product and they took care of it with no hassle, great customer service. They also have certain smaller items that you cant find other places, ex liquid ant bait.

Heating Oil questions, answered by experts

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.

If a geothermal heat pump is installed correctly, then you shouldn’t have to worry about having a backup heat source such as a furnace or oil boiler. However, there are geothermal systems installed that include a backup in case the heat pump fails due to extreme cold. This is simply a backup heat pump you’ll likely never need and not an alternative heat source.

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives).

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

DIY maintenance like filter cleaning is possible, but professional servicing ensures proper pressure, refrigerant levels, and loop performance.

Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.
