Haven Heating and Air Conditioning, Inc., is family owned in South Haven, MI. We have over 25 years experience in the residential and commercial industry and strive to give 100% customer satisfaction

"Communication with this company is like pulling teeth. Our installation team was friendly and had exceptional HVAC knowledge. However, i do not feel like we got quality work for the price tag. After our initial installation, the furnace was left functional but incomplete with no follow up appointment arranged. I had to call multiple times a day( as well as my wife) to get a follow up appointment and get the work finished...ish. When i did FINALLY get a hold of someone via email or telephone, there was always some sort of excuse. After 3 times out to our home, the furnace is in and the issues are fixed...for the most part(not including the hole in my linoleum and a soaked garage). Do yourself a favor and find somebody else."

Heating Oil questions, answered by experts

An evaporator or swamp cooler is a common alternative for small spaces. These coolers blow moist air into a space to help cool it down. They are more affordable than misters and use much less water. However, coolers will not have the same cooling effect as misters, cannot help plants survive the heat, and only reach a small area.

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

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.

Regular inspections, loop flushing, and checking heat exchangers help extend system lifespan.

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.
