Assessment & Estimate

The Haertel Heating and Cooling Guarantee

No high-pressure sales pitch for an HVAC system you don’t want or need. We won’t reinvent the wheel in your home; instead, whenever possible we’ll retrofit to make it work for you. If you like being hands on, visit our showroom, we’ll provide a demonstration of heating and cooling systems to choose from.

Dan Lijewski, Co-Owner

Who Should Consider An Assessment?

  • Is your current gas bill really high?
  • Has your electric bill gone crazy?
  • Have you noticed an especially cold area of your house?
  • Are allergies impacting your quality of life at home?
  • Do you still have outdated furnace, air conditioner, humidifier, or air quality equipment?
  • Is your thermostat from the last century?
  • Are you tired of returning to a cold house after a long day at work?

Note: New project assessments are free! Free assessments are not provided for servicing equipment.

Who Should Be Home?

First Visit. For the initial assessment, it’s helpful to have someone from the household available to let us in, show us around, and provide a list of detailed concerns.

Second Visit. When a financial decision is required, we encourage the homeowner(s) to be available. We’ll present our analysis, answer your questions, and finally recommend steps for achieving optimal comfort in your home. We’ll also suggest a timeline for accomplishing your goals. Though we’re happy to spend as much time as you find helpful, we recommend scheduling 30 minutes for this consultation.

Time-frame

When you contact us for an assessment, we’ll promptly provide you with further information. Generally we are able to schedule an assessment within two weeks of your contact. Once we begin, we’re committed to completing your project in a timely manner.

Financing

If financing is helpful for you, we’re always quick to share how you can save money. We’ll help create a plan for completing your project in stages to alleviate financial pressure.
