Frequently Asked Questions
Donny’s is your knowledgeable source for honest information and assistance. We strive to make temperature control affordable, convenient, and reliable. To get started, we’ve compiled a list of commonly asked questions.
What’s the ideal thermostat setting during the warmer season?
We suggest a temperature of 78° during the day and an adjustment down to 74° overnight.
Are filter changes necessary?
Replacing the filter every month, or 6 months (depending on filter size), especially when equipment is carrying a heavy workload, promotes greater efficiency and reliability.
Why should I replace my condensing unit when my air handler is the problem right now?
If your system is more than 5 years old, technological advances, especially in SEER ratings make it important for your split system to match. Units older than 5 years were not rated. New equipment today must be at least 10 SEER. With mismatched equipment, the benefits of energy efficient units would not be realized.
Should I buy a higher SEER system?
Let your pocketbook and the EERE energy guide on this site be your guide.(go to links, click on EERE site) In many areas, the local electrical utility offers rebates for installation of higher SEER A/C equipment, further reducing your cost.
Should I have an electrostatic or electronic air cleaner installed?
Allergies, dust, pollen, animal hair; if any of these things are a concern to you, definitely upgrade your A/C filtration. You should consult Donny’s HVAC, for the filtration system and other indoor air quality issues that affect your lifestyle needs.
The most common reasons for icing up in the cooling mode are:
Dirty Filters
-Allowing unit to run when outside -temperature is below 70 degrees
-Low Refrigerant charge
**These 3 problems account for at least 90% of all “icing up” situations. Should I have a humidistat put on my A/C system**
Should I repair or replace my HVAC system?
As your HVAC system gets older, efficiency will dramatically decrease. It may start making annoying noises or leak water, needing frequent repairs and parts replacements. When an HVAC unit is acting up and showing its age, you have two options: You can opt for a system overhaul or replace it with a new one.
What’s the best way to prevent HVAC malfunctions?
Regular troubleshooting and maintenance performed by our certified professionals identifies and resolves concerns before they graduate into costly repairs.
What’s the benefit of an Energy Star qualified thermostat?
Energy Star rated programmable, WiFi, and smart thermostats allow set and forget operation, taking on the responsibility of conserving energy without sacrificing comfort. We’d be happy to explain options, features, and the many rewards.
Are there inexpensive ways of reducing demands on the air conditioner?
Keeping blinds and curtains closed to block sunlight prevents the home from heating up during the day and lessens strain on the air conditioner. Ceiling fans are another option, with the rotation of the blades working to push heat upward.
Are there cost-effective methods of lessening the requirements of the heating system?
Insulation prevents heated air from escaping and stops chilly air from coming in. Take the time to seal cracks around windows and doors with caulk or weather stripping and consider adding ceiling fans to push heat downward.
