"Doug Swartz is a con man. When they drilled holes in our yard they never filled the first hole and we had a sinkhole occur. When we had issues with our system a few years back and the system was not heating our kids bedroom, he told us to go buy a space heater to heat up the room; after spending $31,000 on his system. He is the persona of an irresponsible sales person and I would not use this man for his services."

"Will Stahl from Stahl Mechanical called me the same day that I submitted my request for a pro. He came to my home for an estimate a few days later. He was knowledgeable about AC and electric, educating my husband and I regarding the different systems available, cost and efficiency. He and his 2 guys arrived the following week on time and finished the job in less time than estimated. Will was skillful, clean, respectful and friendly. He was genuinely concerned with the quality of his work and assisted us in setting the smart thermostat and returned upon request at no extra charge to adjust the vents to balance the air flow in all the upstairs bedrooms.

Heating Oil questions, answered by experts

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts—an indoor air handler unit and an outdoor heat pump unit. A ductless heat pump system functions similarly to an air-source heat pump system but doesn’t need ductwork to distribute the air. A geothermal heat pump system pulls heat from the ground to help heat your home.

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.

It’s a better use of energy (and your money) NOT to run an ERV system all the time. Most experts recommend that you cycle your ERV system on and off throughout the year. However, the recommended advice could change based on your climate, the number of people in your home, the size and style of your home, and your heating and cooling system. Contact a local pro for more specific advice.

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.
