"Juan is very professional and passionate about what he does. Even though we have an annoying HOA in our community that sets all kinds of rules, he communicated with the HOA ahead of time and showed up at the time we agreed. Despite the fact that the HOA failed to tell us the right way to the roof where AC units are located at the beginning, Juan was very patient and called HOA multiple times to figure things out. The repair was completed quickly and properly. I highly recommend Capella HVAC in San Jose."

As you can see they can?t get a mitre corner completed properly. And then use construction grade plywood material NOT good finished grade. So I?ll do it myself the right way. I wonder if Mr. Pelle?s home is finished in junk material like this. If they can?t do this properly who knows what else is done poorly. Another thing the workman asked where I?d like the thermostat I pointed at a location. Well he just starts drilling away and hit a metal vent.

"We had a wonderful experience with Comfort Energy! The service person, whose name was Chance, did a thorough evaluation of the problem with a focus on saving us as much money as possible, to either repair or replace our 30-year-old heat furnace. He quickly determined that our inlet filter was too dense (it was a Merv 11 and should have been a Merv 8) and that that was probably causing the heater to go off an on every 5-10 minutes. He then tested and confirmed his hypothesis. He also performed a CO test to make sure there wasn't anything more serious going on. Finally, he gave us a good idea of replacement options, which we should probably do before the next Winter, but not necessarily right away. All in all, this is exactly the kind of assessment we needed, and it cost orders of magnitude less than what was estimated by the first service company we had come out. Chance was great, and Comfort Energy is our go-to for heating and cooling service and/or installation from now on."

Heating Oil questions, answered by experts

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.

HVAC systems usually last between 10 and 30 years, with most having a lifespan of around 20 years. Factors that impact a unit’s life expectancy include which brand you choose, how often you use it, and how well you maintain it. To make sure yours lasts as long as possible, make sure to keep it clean and schedule an annual service with an HVAC technician.

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.

A geothermal heat pump system will take about 10 years to pay for itself, and it has a life span of anywhere from about 25 to 50 years. Installing a geothermal heat pump will cost about $14,250 upfront, but it can reduce your energy bills by around 65% when compared to a conventional HVAC system.

Yes, many providers offer organic or eco-friendly treatments. Confirm availability with your contractor.
