Frequently Asked Questions

How often should my system be check or tuned up?

A system tune up and cleaning every six months is a good idea and every three months is even better. A common time to do preventative maintenance is at the beginning of each heating and cooling season but maintenance may be scheduled at any time.

How often should my heating and cooling air filters be changed?

Like service checks, every six months is a good idea and every three months is even better.

Is a yearly maintenance plan worth it?

Especially with heating systems like furnaces, preventative maintenance can potentially save lives. Vent failures can send carbon monoxide into your home while you sleep. Gas and oil leaks are no worth risking. Damage to ductless systems can lead to heating failures and emergency situations if they are not maintained.

So yes, in our opinion, it is well worth spending a reasonable amount to keep things running safely and smoothly. Improved efficiency is not just doing right by the environment but can save you money over the long term as well.

Manufacturer's warranties may be considered invalid if a customer doesn’t have their unit serviced twice a year.

How much do HVAC maintenance contracts cost?

$299 per system (2 visits 1 spring and 1 fall)

Basic HVAC maintenance costs are as follows but depend on what we find.

  • Condenser fan motor blade repair: $750
  • Compressor replacement: $1,400
  • Complete condenser replacement: $3,500

Is a tune up included in my warranty?

Extended warranties and service agreements do not cover the cost of regular heating and air conditioning preventive maintenance.

N.E.T.R. installed a 5-zone Mitsubishi minisplit system in our house. These guys are hard working and know their stuff. The project was also reasonably priced and was done in 3 days (plus 1 day for electrical upgrades to 200 amps). Highly recommended!

After the last few weeks of hot and humid weather, I'm REALLY appreciating our ductless unit. I don't know why we didn't get one installed years ago. We got it late last summer and didn't use it all that much until the last few months. What a difference!
