Handyman doing light plumbing, electrical, moving, assembly, and general home repair. No remodeling or construction. I've been doing many types of repairs for over 30 years. Prompt response and on time to job sites.

"Mike has been an excellent friend and worker for me. I'm so thankful to have found him to take charge of returning a rental house into a prospective home to list on the market. He does great work, responds and communicates well. He's surprised me on a couple of occasions by taking care of some items I thought would require many more dollars to hire a contractor. I didn't mention I live 2,000 miles away from the rental, so it's been a godsend to have Mike onboard. Great guy, does great work."

Heating Oil questions, answered by experts

The most obvious downside is the high upfront cost of buying and installing one of these systems. Additionally, sometimes the system can take a longer time to heat than alternatives like a boiler. Also, if something goes wrong with the geothermal pump, repairs are often significantly more expensive than repairing traditional, above-ground heat pumps.

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.

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.

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

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.
