FAQs
We're replacing an old unit. What's the minimum efficiency we should consider, and are there rebates?
The federal minimum standard is now 14.3 SEER2. Given Pepco's residential rate of $0.16/kWh, upgrading to a 16+ SEER2 unit yields meaningful savings. The Inflation Reduction Act's HEEHRA rebates are active, providing up to $8,000 for qualified high-efficiency heat pump installations, which often makes a superior system cost-competitive with a baseline model after the Pepco rebate of $300-$600 is also applied.
We have gas heat but are considering a heat pump. Is that a good idea for our Maryland winters?
Modern cold-climate heat pumps are effective for Prince George's County winters, especially when paired with your existing gas furnace as a dual-fuel hybrid system. This setup uses the efficient heat pump for most heating, automatically switching to gas during Pepco's peak rate hours from 2 PM to 7 PM or on the handful of deepest freeze nights. This maximizes comfort and cost savings while leveraging your current infrastructure.
Why does our AC struggle when it hits 95°F, even though it was working fine?
HVAC systems in Cheverly are designed to maintain temperature up to a 92°F outdoor design temp. When actual temperatures exceed this, the system runs continuously to minimize the temperature gap, which is normal operation. The newer R-454B refrigerant in modern units maintains better pressure and cooling capacity in this extreme heat compared to older R-410A, but no system can overcome the laws of thermal load beyond its engineered capacity.
Our AC seems fine, but we have water pooling by the indoor unit. Is this a common issue for Cheverly?
Water pooling is a classic sign of condensate drain clogging, which is extremely common for systems installed in Cheverly's 1954-era homes. A unit of that age often has a galvanized steel drain pan that rusts, and the PVC drain line can accumulate sludge from our humid air. Regular maintenance clears the algae and debris, but if the pan itself is corroded, the entire air handler may need replacement to prevent water damage and mold growth.
Our AC just stopped blowing cold air on a hot afternoon. How fast can a technician get to Cheverly Gardens?
A dispatch from our shop near the Cheverly Community Center uses US-50 for direct access. For a no-cool emergency in Cheverly Gardens, we typically confirm a technician on-site within 15-20 minutes. The first actions are to check the circuit breaker and the condensate safety switch, which often trips due to our local humidity, as these are quick fixes you can verify before we arrive.
What should we know about permits and safety for a new AC installation in 2026?
All installations in Prince George's County require a permit from the Department of Permitting, Inspections and Enforcement. Since 2025, new systems predominantly use A2L refrigerants like R-454B, which are mildly flammable. This mandates compliance with updated safety codes: specific leak detectors, revised electrical clearances, and specialized technician certification. A proper permit ensures the installation meets these 2026 standards for safety and insurability.
Our Ecobee thermostat is showing an 'E1' alert. What does that mean for our system?
An Ecobee E1 error indicates the thermostat is not detecting voltage from the equipment, commonly due to a safety lockout. In Cheverly, the primary culprit is often a clogged condensate drain triggering the float switch, which cuts power to prevent overflow. Other local causes include a tripped high-pressure switch from a dirty condenser coil during pollen season or a failed capacitor in the outdoor unit. This alert allows for targeted troubleshooting before a complete failure occurs.
With May pollen and summer ozone, what can we do to improve our home's air quality?
High-MERV filtration is key for pollen, but your existing galvanized steel ductwork requires assessment. While robust, these older ducts often have higher static pressure. Installing a MERV-13 filter without evaluating the system can restrict airflow, causing the furnace to overheat in winter or the AC coil to freeze. A technician can perform a static pressure test to determine if duct modifications or a media cabinet are needed for safe, effective filtration.
