Frequently Asked Questions
My older Boston home has uneven heating, with some rooms freezing and others too warm. What can Crespo Mechanical do?
Uneven heating is a common issue in many Boston homes due to older ductwork or undersized systems. We start with a thorough inspection of your existing HVAC system to diagnose the root cause. Solutions can range from rebalancing your duct system and sealing leaks to recommending a correctly sized heat pump or ductless mini-split system for targeted comfort in problem areas, all while considering the efficiency needs of a New England winter.
My water heater just failed. Do you offer emergency installation or just repair?
Yes, we handle both emergency repairs and full installations for water heaters, including standard tank and efficient tankless models. We'll assess the situation honestly—if a repair is feasible and cost-effective, we'll provide that option. If a replacement is needed, we'll work with you to choose the right unit for your household's needs and schedule the installation promptly to restore your hot water with minimal disruption.
What does your plumbing inspection service cover, especially for preventative maintenance?
Our comprehensive plumbing inspection is designed to catch small issues before they become major problems. We check for leaks, test water pressure, inspect visible pipes for corrosion, assess the condition of fixtures like toilets and water heaters, and look for signs of drainage issues. For Boston homeowners, this is particularly valuable for identifying vulnerable pipes before freezing temperatures hit, helping to prevent costly bursts and water damage.
