Most residential AC installations take one to two days, depending on your home’s setup and the complexity of the job. If we’re replacing an existing system with similar ductwork, it’s usually completed in one day. However, if we need to modify ductwork, upgrade electrical panels, or work around unique features in older Plymouth homes, it might take longer. We’ll give you a realistic timeline upfront so you can plan accordingly. The key is doing the job right, not rushing through it.
The right size depends on several factors specific to your home: square footage, insulation quality, window placement, and ceiling height. Many homeowners assume bigger is better, but an oversized AC actually works less efficiently and costs more to operate. It cycles on and off too frequently, never properly dehumidifying your home. We perform a proper load calculation to determine the exact capacity you need. This ensures optimal efficiency and comfort while avoiding the problems that come with incorrect sizing.
Yes, replacing your AC before it fails completely is usually the smarter move. When systems fail during peak summer heat, you’re often forced to make quick decisions and may end up paying premium rates for emergency service. If your current system is over 10-12 years old, requires frequent repairs, or struggles to keep your home comfortable, it’s time to start planning for replacement. This gives you time to research options, get proper quotes, and schedule installation during less busy periods when you have more flexibility.
Yes, we handle all necessary permits and coordinate with local inspectors as required by Plymouth regulations. AC installation often requires electrical permits, especially if we’re upgrading your electrical panel or running new circuits. We know the local requirements and have established relationships with Plymouth’s building department. This takes the administrative burden off your shoulders and ensures everything is done according to code. You don’t have to worry about navigating permit applications or scheduling inspections – we manage that entire process.
Quality installations rarely have problems, but if issues do arise, we stand behind our work. Most problems with new AC systems stem from installation errors, which is why we test everything thoroughly before considering the job complete. If you experience any issues after installation, we respond quickly to diagnose and resolve them. Additionally, your new equipment comes with manufacturer warranties, and our Dempsey Comfort Club provides ongoing support and maintenance to prevent problems before they start. You’re not left to figure things out on your own.
Absolutely. Many older Plymouth homes were built before central air conditioning became standard, but that doesn’t mean you can’t have efficient cooling. We have several options depending on your home’s layout and your budget. These include ductless mini-split systems, which are highly efficient and don’t require extensive ductwork modifications. We can also design and install new ductwork if that makes more sense for your situation. During our assessment, we’ll explain the best options for your specific home and help you understand the benefits of each approach.
